Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations. The following discussion should be read in conjunction with the financial statements appearing elsewhere in this Form 10-Q and within our Form 10-K for the year ending December 31, 2000. This report contains forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below under the heading "Risk Factors," and other factors detailed in the Company's filings with the Securities and Exchange Commission, specifically our Form 10-K for the year ending December 31, 2000. Overview We design, manufacture and market power quality products that provide the consistent, reliable electric power required by today's digital economy. We believe that we are the first company to commercialize a flywheel energy storage system that provides a highly reliable, low-cost and non-toxic replacement for lead-acid batteries used in conventional power quality installations. Leveraging our expertise in this technology and in conjunction with Caterpillar, the leading maker of engine generators for the power reliability market, we have developed a battery-free power quality system, which is marketed under the Caterpillar brand name (Cat UPS(TM)). Our products are sold for use in the facilities of companies in many different industries that all share a critical need for reliable, high-quality power, such as Internet service providers, semiconductor manufacturers, telecommunications providers, hospitals, electric utilities and broadcasters. As an extension of these existing product lines, we are developing a fully integrated continuous power system. The initial target market for this product is the telecommunications industry. Since 1996, we have focused our efforts and financial resources primarily on the design and development of our CleanSource(R) line of power quality products and on establishing effective OEM channels to market our products. As of March 31, 2001, we had generated an accumulated deficit of $59.4 million and expect to continue to sustain operating losses for the next several quarters. We initially funded our operations through sales of shares of our preferred stock, which have resulted in gross proceeds of approximately $42.6 million. We believe the proceeds from our August 2000 initial public offering, approximately $138.4 million net of commissions and issuance costs, together with cash balances on hand prior to August 2000 will be sufficient to meet our capital requirements through at least the next 24 months. Our cash and investments position at March 31, 2001 was $137.0 million. Since our inception, a small number of customers have accounted for the majority of our annual sales. During 1999, our four largest customers accounted for 89% of our sales, with our largest customer, Caterpillar and its dealer network, accounting for 39%. In 2000 and the first quarter of 2001, our business level with Caterpillar and its dealer network grew substantially, accounting for 96% and 78% respectively of our revenue due to the commercial introduction of the CleanSource UPS product line. We expect to continue to be dependent on a few OEM customers, primarily Caterpillar, for the majority of our sales for the foreseeable future. 6

With the commercial release of our second generation product line, CleanSource UPS, in May 2000 under the Caterpillar brand name, and a growing market demand for power quality equipment, we believe the demand for our products will increase significantly. To prepare for this anticipated growth in demand and to position us for future growth, we have increased and expect to continue to increase the scale of our operations in the following ways: . expand our manufacturing facilities and add manufacturing personnel to address anticipated increases in product demand; . increase our personnel levels in product development and engineering to accelerate time to market on new products and enhance existing product lines; and . add sales and marketing personnel to support our OEM customers. We believe that although these efforts will increase our operating expenses, they will also enable us to realize significant revenue growth. Results of Operations Product Revenue. Product revenue primarily consists of sales of our CleanSource power quality products. Sales increased $4.9 million to $5.1 million for the three months ended March 31, 2001 from $182,000 for the three months ended March 31, 2000. This increase was primarily attributable to a ramp up in the sales of our recently launched CleanSource UPS product line. In the three months ended March 31, 2001, we sold 101 quarter-megawatt flywheel units. The majority of these units were sold to our CleanSource UPS distribution partner, Caterpillar. Cost of goods sold. Cost of goods sold includes the cost of component parts of our product that are sourced from suppliers, personnel, equipment and other costs associated with our assembly and test operations, shipping costs, and the costs of manufacturing support functions such as logistics and quality assurance. Cost of goods sold increased $6.0 million to $6.5 million for the three months ended March 31, 2001 from $521,000 for the three months ended March 31, 2000. This increase was primarily due to product costs that grew commensurate with the increase in sales and a scale up in our manufacturing operations. In anticipation of future demand for our products, we plan to significantly expand our manufacturing capacity by increasing both our manufacturing facilities and production personnel, which will increase our manufacturing cost base. We believe gross margins will improve over time as our product volumes increase, and we achieve greater economies of scale in production and in purchasing component parts, and introduce engineering design savings. Research and development. Research and development expense primarily consists of compensation and related costs of employees engaged in research, development and engineering activities, third party consulting and development activities, as well as an allocated portion of our occupancy costs. Research and development expense increased $2.0 million, or 142%, to $3.5 million for the three months ended March 31, 2001 from $1.5 million for the three months ended March 31, 2000. The increase in research and development expense was primarily due to an increase in product development activities on our next generation 6 kilowatt continuous power system. We believe that research and development expense will continue to increase during 2001 and thereafter as we continue to develop new products and enhance existing product lines. 7

Selling, general and administrative. Selling, general and administrative expense is primarily comprised of compensation and related costs for sales, marketing and administrative personnel, selling and marketing expenses, professional fees and reserves for bad debt. Selling, general and administrative expense increased approximately $1.6 million, or 150%, to $2.7 million for the three months ended March 31, 2001 from $1.1 million for the three months ended March 31, 2000. The increase in selling, general and administrative expense was principally due to increased personnel in our sales and marketing organizations in order to support our main OEM channel partner's sales and service ramp up of the CleanSource UPS product line. We also incurred higher administrative costs associated with the added responsibilities and reporting requirements of a pubic company. We believe that selling, general and administrative expense will increase in future periods as we add sales, marketing and administrative personnel and costs to position us for future sales growth and to assist in the administration of an expanding work force. Amortization of deferred stock compensation. Deferred stock compensation reflects the difference between the exercise price of option grants to employees and the estimated fair value determined subsequently by us of our common stock at the date of grant. We are amortizing deferred stock compensation as an operating expense over the vesting periods of the applicable options, which resulted in amortization expense of $1.3 million for the three months ended March 31, 2001 and $1.3 million for the three months ended March 31, 2000. We expect the amortization expense to decrease during and after 2001, as the options that were granted at exercise prices less than the estimated fair value determined subsequently by us become fully vested. Interest income. Interest income increased $1.9 million to $2.2 million for the three months ended March 31, 2001 from $370,000 for the three months ended March 31, 2000. This is primarily due to the increase in our average cash balance for the three month period of 2001 of $140.6 million compared to an average cash and investments balance of $24.1 million for the first quarter of 2000. The increase in our cash and investments balance is primarily associated with the approximately $138.4 million raised as part of our August 2000 initial public offering. Change in fair value of warrants. Due to the redemption feature of warrants we had outstanding in 1999 and 2000, we recorded a liability associated with the fair value of the warrants on the balance sheet and recorded changes in fair value of the warrants in expense. We calculated the fair value of the warrants using a Black-Scholes pricing model. In 2000, the fair value of the underlying common stock increased substantially, resulting in an increase in the warrant value and corresponding expense. Expense recorded for the three months ended March 31, 2001 was $0 and $1.0 million for the same period in 2000 as a result of the conversion of the warrants to common stock as part of our initial public offering. Liquidity and Capital Resources Our principal source of liquidity as of March 31, 2001 consisted of $137.0 million of cash, cash equivalents and investments. In August 2000, we completed a successful initial public offering, raising approximately $138.4 million, net of commissions and issuance expenses. This is in addition to our private financing efforts, including the sale of shares of our preferred stock, which have resulted in gross 8

proceeds of approximately $42.6 million, and $5.0 million in development funding received from Caterpillar in 1999. During the three months ended March 31, 2001, cash used by operating activities was $8.4 million, which compares to $2.5 million of cash used by operating activities for the three months ended March 31, 2000. The cash usage in each of these periods was primarily attributable to our focus on the development of products and the expansion of our manufacturing operations and sales activities. Capital expenditures were $1.5 million for the three months ended March 31, 2001 and $589,000 for the three months ended March 31, 2000. We made these expenditures to acquire engineering test equipment, and to purchase manufacturing equipment to facilitate production testing, as well as for general computer equipment and software for administrative purposes. We expect to incur approximately $6.0 to $10.0 million in additional costs in 2001 primarily on the build out of our new manufacturing facility. We believe our existing cash balance at March 31, 2001 will be sufficient to meet our capital requirements through at least the next 24 months, although we might elect to seek additional funding prior to that time. Beyond the next 24 months, our capital requirements will depend on many factors, including the rate of sales growth, the market acceptance of our products, the rate of expansion of our sales and marketing activities, the rate of expansion of our manufacturing facilities, and the timing and extent of research and development projects. Although we are not a party to any agreement or letter of intent with respect to a potential acquisition, we may enter into acquisitions or strategic arrangements in the future which could also require us to seek additional equity or debt financing. Quantitative and Qualitative Disclosures About Market Risk Our interest income is sensitive to changes in the general level of U.S. interest rates, particularly because the majority of our investments are in short-term instruments. We believe that our investment policy is conservative, both in terms of the average maturity of investments that we allow and in terms of the credit quality of the investments we hold. We estimate that a 1% decrease in market interest rates would decrease our interest income by approximately $1.3 million. Because of the short-term nature of the majority of our investments, we do not believe a 1% decline in interest rates would have a material effect on their fair value. We invest our cash in a variety of financial investments, including bank time deposits, taxable and tax-advantaged variable rate and fixed rate obligations of corporations, municipalities, and local, state and national government entities and agencies. These investments are denominated in U.S. dollars. 9

Risk Factors That May Affect Future Results You should carefully consider the following risks and all other information contained in this filing before deciding to invest in our common stock. Additional risks and uncertainties that we are unaware of or that we currently deem immaterial also may become important factors that affect us. We have incurred significant losses and anticipate losses for the next several quarters. We have incurred operating losses since our inception and expect to continue to incur losses for the next several quarters. As of March 31, 2001, we had an accumulated deficit of $59.4 million. To date, our product revenue has been insignificant, and we have funded our operations principally through the sale of our stock. We will need to generate significant revenue to achieve profitability, and we cannot assure you that we will ever realize sufficient revenue to achieve profitability. We also expect to incur significant product development, sales and marketing and administrative expenses and, as a result, we expect to continue to incur losses. Due to our limited operating history and the uncertain market acceptance of our products, we may never achieve significant revenue and may have difficulty accurately predicting revenue for future periods and appropriately budgeting for expenses. We have generated a total of $11.9 million in product revenue since January 1, 1998, and we have sold fewer than 275 CleanSource DC and CleanSource UPS products. We are uncertain whether our products will achieve market acceptance such that our revenues will increase or whether we will be able to achieve significant revenue. Therefore, we have a very limited ability to predict future revenue. Our limited operating experience, the uncertain market acceptance for our products, and other factors that are beyond our control make it difficult for us to accurately forecast our quarterly and annual revenue. However, we use our forecasted revenue to establish our expense budget. Most of our expenses are fixed in the short term or incurred in advance of anticipated revenue. As a result, we may not be able to decrease our expenses in a timely manner to offset any revenue shortfall. Further, we are expanding our staff and facilities and increasing our expense levels in anticipation of future revenue growth. If our revenue does not increase as anticipated, we will incur significant losses. Our business is subject to fluctuations in operating results, which could negatively impact the price of our stock. Our product revenue, expense and operating results have varied in the past and may fluctuate significantly in the future due to a variety of factors, many of which are outside of our control. These factors include, among others: . the timing of orders from our customers and the possibility that these customers may change their order requirements with little or no advance notice to us; . the rate of adoption of our fly-wheel-based energy storage system as an alternative to lead-acid batteries; 10

. the deferral of customer orders in anticipation of new products from us or other providers of power quality systems; . the ongoing need for short-term power outage protection in traditional UPS systems; . the uncertainty regarding the adoption of our current and future products, including our recently introduced CleanSource UPS product and our fully integrated CPS, which we expect to commercially introduce by the end of 2001; and . the rate of growth of the markets for our products. Our business is dependent on the market for power quality products, and if this market does not expand as we anticipate, or if alternatives to our products are successful, our business will suffer. The market for power quality products is rapidly evolving and it is difficult to predict its potential size or future growth rate. Most of the organizations that may purchase our products have invested substantial resources in their existing power systems and, as a result, may be reluctant or slow to adopt a new approach. Moreover, our products are alternatives to existing UPS and CPS systems and may never be accepted by our customers or may be made obsolete by other advances in power quality technologies. Improvements may also be made to the existing alternatives to our products that could render them less desirable or obsolete. We have limited product offerings, and our success depends on our ability to develop in a timely manner new and enhanced products that achieve market acceptance. We have only one principal product that has any significant operating history at customer sites, CleanSource DC, and we have only recently introduced our CleanSource UPS product. To grow our revenue, we must rely on Caterpillar to successfully market our CleanSource UPS product, and we must develop and introduce to market new products and product enhancements in a timely manner. Even if we are able to develop and commercially introduce new products and enhancements, they may not achieve market acceptance. This would substantially impair our revenue prospects. Failure to expand our distribution channels and manage our distribution relationships could impede our future growth. The future growth of our business will depend in part on our ability to expand our existing relationships with OEMs, to identify and develop additional channels for the distribution and sale of our products and to manage these relationships. As part of our growth strategy, we intend to expand our relationships with OEMs and to develop relationships with new OEMs. We will also look to identify and develop relationships with additional partners that could serve as distributors for our products. Our inability to successfully execute this strategy and to reduce our reliance on Caterpillar could impede our future growth. 11

We are heavily dependent on our relationship with Caterpillar. If our relationship is unsuccessful, our business and revenue will suffer. If our relationship with Caterpillar is not successful, or if Caterpillar's distribution of our CleanSource UPS product is not successful, our business and revenue will suffer. Pursuant to a development agreement, Caterpillar provided us with $5.0 million in funding to support the development of our CleanSource UPS product. In exchange for this payment, Caterpillar received co-ownership of the proprietary rights in this product. Either we or Caterpillar may license to other entities the intellectual property that we jointly own without seeking the consent of the other and all licensing revenue generated by licensing this intellectual property will be solely retained by the licensing party. However, we may not license the joint intellectual property to specifically identified competitors of Caterpillar until January 1, 2005. Caterpillar may terminate this agreement at any time by giving us 90 days' advance written notice. We also have a distribution agreement with Caterpillar. In 2000 and the first quarter of 2001, our business level with Caterpillar and its dealer network accounted for 96% and 78% of our product revenue, respectively. Pursuant to the distribution agreement with Caterpillar, they are the exclusive distributor, subject to limited exceptions, of our CleanSource UPS product. Caterpillar is not obligated to purchase any CleanSource UPS units. We depend on a limited number of OEM customers for the vast majority of our revenue and service and support functions. The loss or significant reduction in orders, or the failure to provide adequate service and support to the end users of our products, from any key OEM customer, particularly Caterpillar, would significantly reduce our revenue. We rely on OEMs as a primary distribution channel because they are able to sell our products to a large number of end user organizations. We further rely on our OEMs to provide service and support to the end users of our products because they have the experience and personnel to perform such activities. We believe that the use of OEM channels will enable our products to achieve broad market penetration, while we devote a limited amount of our resources to sales, marketing and customer service and support. Our operating results in the foreseeable future will continue to depend on sales to a relatively small number of OEM customers, primarily Caterpillar. For example, in 2000 and the first quarter of 2001, our business level with Caterpillar and its dealer accounted for 96% and 78% of our revenue, respectively. Therefore, the loss of our key OEM customer, Caterpillar, or a significant reduction in sales to Caterpillar and its dealers, would significantly reduce our revenue. We also have granted Caterpillar semi-exclusive worldwide rights to distribute our CleanSource UPS product, provided that they meet minimum annual sales requirements. These restrictions will further increase our dependence upon Caterpillar. However, Caterpillar is not obligated to purchase any CleanSource UPS units under this agreement. We may have difficulty managing the expansion of our operations. We are undergoing rapid growth in the number of our employees, the size of our physical facilities and the scope of our operations. For example, we had 38 employees on January 1, 1998, 126 employees on June 30, 2000 and 202 employees on March 31, 2001. Such rapid expansion is likely to place a significant strain on our senior management team and other resources. Our business, prospects, results of operations or financial condition could be harmed if we encounter 12

difficulties in effectively managing the budgeting, forecasting and other process control issues presented by such a rapid expansion. We have no experience manufacturing our products in the quantities we expect to sell in the future. To be financially successful, we will have to manufacture our products in commercial quantities at acceptable costs while also preserving the quality levels achieved in manufacturing these products in more limited quantities. This presents a number of technological and engineering challenges for us. We cannot assure you that we will be successful in executing the planned expansion of our manufacturing activities. We have not previously manufactured our products in high volume. We do not know whether or when we will be able to develop efficient, low-cost manufacturing capability and processes that will enable us to meet the quality, price, engineering, design and product standards or production volumes required to successfully manufacture large quantities of our products. Even if we are successful in developing our manufacturing capability and processes, we do not know whether we will do so in time to meet our product commercialization schedule or to satisfy the requirements of our customers. We are subject to increased inventory risks and costs because we outsource the manufacturing of components of our products in advance of binding commitments from our customers to purchase our products. To assure the availability of our products to our OEM customers, we outsource the manufacturing of components prior to the receipt of purchase orders from OEM customers based on their forecasts of their product needs. However, these forecasts do not represent binding purchase commitments, and we do not recognize revenue for such products until the product is shipped to the OEM. As a result, we incur inventory and manufacturing costs in advance of anticipated revenue. As demand for our products may not materialize, this product delivery method subjects us to increased risks of high inventory carrying costs and obsolescence and may increase our operating costs. In addition, we may from time to time make design changes to our products, which could lead to obsolescence of inventory. We depend on sole source and limited source suppliers for certain key components, and if we are unable to buy these components on a timely basis, our delayed ability to deliver our products to our customers may result in reduced revenue and lost sales. We purchase a power module and a microprocessor for our products from sole sources. We do not have long-term contracts with most of our suppliers, and to date most of our component purchases have been made in relatively small volumes. As a result, if our suppliers receive excess demand for their products, we may receive a low priority for order fulfillment as large volume customers will receive priority. If we are delayed in acquiring components for our products, the manufacture and shipment of our products also will be delayed. We generally use a twelve-month forecast of our future product sales to determine our component requirements. Lead times for ordering materials and components vary significantly and depend on factors such as specific supplier requirements, contract terms, the extensive production time required and current market demand for such components. Some of these delays may be substantial. As a 13

result, we purchase these components in large quantities to protect our ability to deliver finished products. If we overestimate our component requirements, we may have excess inventory, which will increase our costs. If we underestimate our component requirements, we will have inadequate inventory, which will delay our manufacturing and render us unable to deliver products to customers on scheduled delivery dates. If we are unable to obtain a component from a supplier or if the price of a component has increased substantially, we will be required to manufacture the component internally, which will result in delays. Manufacturing delays could negatively impact our ability to sell our products and could damage our customer relationships. We depend on key personnel to manage our business and develop new products in a rapidly changing market, and if we are unable to retain our current personnel and hire additional personnel, our ability to develop and sell our products could be impaired. We believe our future success will depend in large part upon our ability to attract and retain highly skilled managerial, engineering and sales and marketing personnel. In particular, due to the relatively early stage of our business, we believe that our future success is highly dependent on Joseph F. Pinkerton, III, our founder, chief executive officer and president, to provide continuity in the execution of our growth plans. While we have severance arrangements in place with Mr. Pinkerton and with David S. Gino, our chief financial officer, we do not have long-term employment agreements in place with any of our employees. The loss of the services of any of our key employees, the inability to attract or retain qualified personnel in the future or delays in hiring required personnel, particularly engineers and sales personnel, could delay the development and introduction of, and negatively impact our ability to sell, our products. We are a relatively small company with limited resources compared to some of our current and potential competitors, and competition within our markets may limit our sales growth. The markets for power quality and power reliability are intensely competitive. There are many companies engaged in all areas of traditional and alternative UPS and CPS systems in the United States, Canada and abroad, including, among others, major electric and specialized electronics firms, as well as universities, research institutions and foreign government-sponsored companies. There are many companies located in the United States, Canada and abroad that are developing flywheel-based energy storage systems and flywheel-based power quality systems. We also compete indirectly with companies that are developing other types of power technologies, such as superconducting magnetic energy storage, ultra-capacitors and dynamic voltage restorers. Many of our current and potential competitors have longer operating histories, significantly greater resources, broader name recognition and a larger customer base than we have. As a result, these competitors may have greater credibility with our existing and potential customers. They also may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale of their products than we can to ours, which would allow them to respond more quickly than us to new or emerging technologies or changes in customer requirements. In addition, some of our current and potential competitors have established supplier or joint development relationships with our current or potential customers. These competitors may be able to leverage their existing relationships to discourage these customers from purchasing products from us or to persuade them to replace our products with their products. Increased competition could decrease our prices, reduce our sales, lower our margins, 14

or decrease our market share. These and other competitive pressures could prevent us from competing successfully against current or future competitors and could materially harm our business. If we are unable to protect our intellectual property, we may be unable to compete. Our products rely on our proprietary technology, and we expect that future technological advancements made by us will be critical to sustain market acceptance of our products. Therefore, we believe that the protection of our intellectual property rights is, and will continue to be, important to the success of our business. We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We also enter into confidentiality or license agreements with our employees, consultants and business partners and control access to and distribution of our software, documentation and other proprietary information. Despite these efforts, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where applicable laws may not protect our proprietary rights as fully as in the United States. In addition, the measures we undertake may not be sufficient to adequately protect our proprietary technology and may not preclude competitors from independently developing products with functionality or features similar to those of our products. Our efforts to protect our intellectual property may cause us to become involved in costly and lengthy litigation, which could seriously harm our business. In recent years, there has been significant litigation in the United States involving patents, trademarks and other intellectual property rights. Although we have not been involved in intellectual property litigation, we may become involved in litigation in the future to protect our intellectual property or defend allegations of infringement asserted by others. Legal proceedings could subject us to significant liability for damages or invalidate our intellectual property rights. Any litigation, regardless of its outcome, would likely be time consuming and expensive to resolve and would divert management's time and attention. Any potential intellectual property litigation also could force us to take specific actions, including: . cease selling our products that use the challenged intellectual property; . obtain from the owner of the infringed intellectual property right a license to sell or use the relevant technology or trademark, which license may not be available on reasonable terms, or at all; or . redesign those products that use infringing intellectual property or cease to use an infringing trademark. Any acquisitions we make could disrupt our business and harm our financial condition. Although we are not currently negotiating any material business or technology acquisitions, as part of our growth strategy, we intend to review opportunities to acquire other businesses or technologies that would complement our current products, expand the breadth of our markets or 15

enhance our technical capabilities. We have no experience in making acquisitions. Acquisitions entail a number of risks that could materially and adversely affect our business and operating results, including: . problems integrating the acquired operations, technologies or products with our existing business and products; . potential disruption of our ongoing business and distraction of our management; . difficulties in retaining business relationships with suppliers and customers of the acquired companies; . difficulties in coordinating and integrating overall business strategies, sales and marketing, and research and development efforts; . the maintenance of corporate cultures, controls, procedures and policies; . risks associated with entering markets in which we lack prior experience; and . potential loss of key employees. We may require substantial additional funds in the future to finance our product development and commercialization plans. Our product development and commercialization schedule could be delayed if we are unable to fund our research and development activities or the development of our manufacturing capabilities with our revenue, cash on hand and proceeds from our initial public offering. We expect that our current cash and investments, together with our other available sources of working capital, will be sufficient to fund development activities for at least 24 months. However, unforeseen delays or difficulties in these activities could increase costs and exhaust our resources prior to the full commercialization of our products under development. We do not know whether we will be able to secure additional funding, or funding on terms acceptable to us, to continue our operations as planned. If financing is not available, we may be required to reduce, delay or eliminate certain activities or to license or sell to others some of our proprietary technology. Our stock price may be volatile. Since our IPO in August 2000, we have experienced significant volatility in our stock price. The market price of our common stock may fluctuate significantly in response to numerous factors, some of which are beyond our control, including the following: . actual or anticipated fluctuations in our operating results; . changes in financial estimates by securities analysts or our failure to perform in line with such estimates; . changes in market valuations of other technology companies, particularly those that sell products used in power quality systems; . announcements by us or our competitors of significant technical innovations, acquisitions, strategic partnerships, joint ventures or capital commitments; . introduction of technologies or product enhancements that reduce the need for flywheel energy storage systems; . the loss of one or more key OEM customers; and . departures of key personnel. 16
