NOTE 1 - CONDENSED FINANCIAL STATEMENTS

The accompanying financial statements have been prepared by the Company without audit. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows at June 30, 2016 and for all periods presented herein, have been made.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted.  It is suggested that these condensed financial statements be read in conjunction with the financial statements and notes thereto included in the Company's December 31, 2015 audited financial statements.  The results of operations for the periods ended June 30, 2016 and 2015 are not necessarily indicative of the operating results for the full years.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Recent Accounting Pronouncements

The Company has evaluated recent accounting pronouncements and their adoption has not had or is not expected to have a material impact on the Company's financial position, or statements.

Inventory

Inventory is stated at the lower of cost or market.  The Company's inventory consists of finished goods and raw material and is located in Vista, California, consisting of the following:

	June 30,			December 31,
Location : Vista, CA	2016			2015
Raw materials	$	1,118,623		$	1,093,890
Finished goods		1,201,000			1,263,089
Allowance for obsolete inventory		(249,516	)		(249,516	)

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Property and Equipment

Property and equipment at June 30, 2016 and December 31, 2015 consisted of the following:

	June 30,			December 31,
	2016			2015
Production equipment	$	61,960		$	61,960
Computers/Office equipment		28,540			28,540
Tooling equipment		12,380			12,380
Leasehold Improvements		42,451			42,451
Less: accumulated depreciation		(100,362	)		(86,180	)
Total	$	44,969		$	59,151

Depreciation expense for the six month periods ended June 30, 2016 and June 30, 2015 was $14,183 and $14,781, respectively.

Basic and Diluted Loss per Share

The computation of basic earnings per share of common stock is based on the weighted average number of shares outstanding during the periods presented. The computation of fully diluted earnings per share includes common stock equivalents outstanding at the balance sheet date. The Company had 142,965 and -0- stock options and warrants that would have been included in the fully diluted earnings per share as of June 30, 2016 and December 31, 2015, respectively.  

Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification Topic 740, Income Taxes ("Topic 740"), which requires the recognition of deferred tax liabilities and assets at currently enacted tax rates for the expected future tax consequences of events that have been included in the financial statements or tax returns. A valuation allowance is recognized to reduce the net deferred tax asset to an amount that is more likely than not to be realized.

Topic 740 provides guidance on the accounting for uncertainty in income taxes recognized in a company's financial statements. Topic 740 requires a company to determine whether it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. If the more likely-than-not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements.

At the adoption date of November 1, 2007, the Company had no unrecognized tax benefit which would affect the effective tax rate if recognized. The Company includes interest and penalties arising from the underpayment of income taxes in the statements of operations in the provision for income taxes. As of June 30, 2016 and December 31, 2015 the Company had no accrued interest or penalties related to uncertain tax positions. The Company files an income tax return in the U.S. federal jurisdiction and the state of California. With few exceptions, the Company is no longer subject to U.S. federal, state, and local, or non-U.S. income tax examinations by tax authorities for years before 2008.

NOTE 4 - STOCK OPTIONS AND WARRANTS (CONTINUED)

The Company recognizes compensation expense for stock-based awards expected to vest on a straight-line basis over the requisite service period of the award based on their grant date fair value.  The Company estimates the fair value of stock options using a Black-Scholes option pricing model which requires management to make estimates for certain assumptions regarding risk-free interest rate, expected life of options, expected volatility of stock and expected dividend yield of stock. When determining expected volatility, the Company considers the historical performance of the Company's stock, as well as implied volatility. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant, based on the options' expected term. The expected term of the options is based on the Company's evaluation of option holders' exercise patterns and represents the period of time that options are expected to remain unexercised. The Company uses historical data to estimate the timing and amount of forfeitures.

The following table presents the assumptions used to estimate the fair values of the stock options granted:

	June 30, 2016			June 30, 2015
Expected volatility		87	%		74	%
Expected dividends		0	%		0	%
Expected term	7 Years			5 Years
Risk-free interest rate		1.52	%		1.58	%

A summary of the status of the options and warrants granted at June 30, 2016 and December 31, 2015 and changes during the periods then ended is presented below:

Results of Operations

For the three months ended June 30, 2016 and 2015

Revenues were $252,316 for the three months ended June 30, 2016 compared with $591,185 for the three months ended June 30, 2015, a decrease of $338,869, or 57%. The results for the quarter reflect the impact of the timing of orders between the completion of pilot programs and the ramp-up of fleet conversions on a larger scale.

Our cost of sales was $148,316 for the three months ended June 30, 2016 compared with $269,003 for the three months ended June 30, 2015, a decrease of $120,687. Our gross margin was 41% for the three months ended June 30, 2016 compared with 54% in the same period in 2015. The gross margin for the quarter was impacted by the product mix but is still consistent with management's target range.

Our operating expenses for the three months ended June 30, 2016 were $395,334 compared with $494,230 in the same period in 2015, a decrease of $98,896 or 20%. General and administrative expense for the three months ended June 30, 2016 was $341,461 as compared with $396,841 for the three months ended June 30, 2015. Major components of general and administrative expenses for the three months ended June 30, 2016 were professional fees of $20,593, rent expense of $20,317, and salary and wages of $122,076. This compares to professional fees of $23,244, rent expense of $45,653 and salaries and wages of $129,241 for the three months ended June 30, 2015.  For the three months ended June 30, 2016 research and development outlays were decreased to $46,897 compared with $89,655 for the three months ended June 30, 2015.

Our net loss for the three months ended June 30, 2016 was $292,939, or $0.01 per share, compared with a net loss of $168,280, or $0.01 per share, for the three months ended June 30, 2015. The increased loss was due primarily to the reduction in sales.

Page 10

Results for the three months ended June 30, 2016 reflect the impact of non-cash expenses, including the value of options and warrants granted in the amount of $81,969 and depreciation and amortization of $6,976. For the three month period a year earlier, non-cash expenses for the value of options and warrants granted were $53,486, with depreciation and amortization of $7,734.

For the six months ended June 30, 2016 and 2015

Revenues decreased to $591,899 for the six months ended June 30, 2016 from $1,041,885 for the six months ended June 30, 2015, a decrease of $449,986 or 43%. The results for the period reflect the impact of the timing of orders between the completion of pilot programs and the ramp-up of fleet conversions on a larger scale.

Our cost of sales decreased to $320,493 for the six months ended June 30, 2016 from $520,648 for the six months ended June 30, 2015, a decrease of $200,155. Our gross margin was 46% for the six months ended June 30, 2016 compared to 50% in 2015. The gross margin for the period was impacted by the product mix but is still consistent with management's target range.

Our operating expenses for the six months ended June 30, 2016 were $763,023 compared to $929,656 in 2015, a decrease of $166,633 or 18%.  General and administrative expense for the six months ended June 30, 2016 was $654,257 as compared to $747,893 for the six months ended June 30, 2015.  The decrease is due primarily to lower travel expense of $10,345 for the six months ended June 30, 2016 as compared to $ $35,214 for the six months ended June 30, 2015, lower legal expense of $24,960 for the six months ended June 30, 2016 as compared to $36,937 for the six months ended June 30, 2015 and options expense of $ 118,068 for the six months ending June 30, 2016 as compared to $ 87,089 for the six months ended June 30, 2015.  Major components of general and administrative expenses for the six months ended June 30, 2016 were professional fees of $51,978, rent expense of $48,053 and salary and wages of $241,362. This compares to professional fees of $59,787, rent expense of $74,983, and salary and wages of $265,486 for the six months ended June 30, 2015. Research and development outlays were decreased to $94,303 for the six months ended June 30, 2016 compared to $166,239 for the six months ended June 30, 2015.

Our net loss for the six months ended June 30, 2016 was $489,683, or $0.02 per share, compared to a net loss of $405,442, or $0.02 per share, for the six months ended June 30, 2015. The increased loss was the result of reduced sales.

Results for the six months ended June 30, 2016 reflect the impact of non-cash expenses, including the value of options and warrants granted in the amount of $118,068 and depreciation and amortization of $14,463. For the six-month period a year earlier, non-cash expenses for the value of options and warrants granted were $87,089 and depreciation and amortization of $15,524.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash provided by operating activities and available working capital. Additionally, from time to time we may raise funds from the equity capital markets to fund our research and development programs, expansion of our business and general operations.

At June 30, 2016, our current liabilities totaled $616,989 and our current assets totaled $2,174,723, resulting in positive working capital of $1,557,734 and a current ratio of 3.52.

Page 11

We have no firm commitments or obligations for capital expenditures.  However, substantial discretionary expenditures may be required to enable us to conduct existing and planned product research, design, development, manufacturing, marketing and distribution of our products. We may need to raise additional capital to facilitate growth and support our long-term product development, manufacturing, and marketing programs. The Company has no established bank-financing arrangements, therefore, it is possible that we need to seek additional financing through subsequent future public or private sales of our securities, including equity securities. We may also seek funding for the development, manufacturing, and marketing of our products through strategic partnerships and other arrangements with corporate partners. There can be no assurance, however, that such collaborative arrangements or additional funds will be available when needed, or on terms acceptable to us, if at all. If adequate funds are not available, we may be required to curtail one or more of our research and development programs.

We have historically incurred significant losses, which have resulted in a total accumulated deficit of $18,339,095 at June 30, 2016, of which $5,604,135 is a direct result of derivative expense and change in fair value of derivative liability and is unrelated to, and has no effect on, our operations or cash flow.

Operating Activities

We realized a negative cash flow from operations of $178,721 for the six months ended June 30, 2016 compared with a negative cash flow of $148,431 during the six months ended June 30, 2015.

Included in the net loss of $489,683 for the six months ended June 30, 2016 are non-cash expenses, which are not a drain on our capital resources. During the six months ended June 30, 2016, the non-cash expenses include the value of options and warrants granted in the amount of $118,068 and depreciation and amortization of $14,463. Excluding these non-cash amounts, our EBITDA for the six months ended June 30, 2016 would have been a loss of $357,152.

Off-Balance Sheet Arrangements

None.

Critical Accounting Policiesand Estimates

Accounting Method and Use of Estimates

The Company's financial statements are prepared using the accrual method of accounting. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Areas where significant estimates are required include the following:

Accounts Receivable

Trade receivables are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by identifying troubled accounts and by using historical experience applied to an aging of accounts.

Inventory

Inventory is stated at the lower of cost or market. The Company's inventory consists of finished goods and raw material. The Company identifies items in its inventory that have not been sold in a timely manner. Accordingly, the Company has established an allowance for the cost of such obsolete inventory.

Page 12

Long-lived assets

The Company assesses the recoverability of its long lived assets annually and whenever circumstances would indicate that there may be an impairment. The Company compares the estimated undiscounted future cash flows to the carrying value of the long lived assets to determine if an impairment has occurred. In the event that an impairment has occurred, the Company recognizes the impairment immediately.

Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification Topic 740, which requires the recognition of deferred tax liabilities and assets at currently enacted tax rates for the expected future tax consequences of events that have been included in the financial statements or tax returns. A valuation allowance is recognized to reduce the net deferred tax asset to an amount that is more likely than not to be realized. The Company uses historical experience to determine the likely-hood of realization of deferred tax liabilities and assets.

Revenue Recognition

The Company recognizes revenue from the sale of new natural gas engines and components to convert existing diesel engines to natural gas engines. Revenue is recognized upon shipment of the products, and when collection is reasonably assured.

Accounting for Income Taxes

The Company accounts for income taxes in accordance with Accounting Standards Codification Topic 740, Income Taxes ("Topic 740"), which requires the recognition of deferred tax liabilities and assets at currently enacted tax rates for the expected future tax consequences of events that have been included in the financial statements or tax returns. A valuation allowance is recognized to reduce the net deferred tax asset to an amount that is more likely than not to be realized.

Topic 740 provides guidance on the accounting for uncertainty in income taxes recognized in a company's financial statements. Topic 740 requires a company to determine whether it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. If the more likely-than-not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements.

At the adoption date of November 1, 2007, the Company had no unrecognized tax benefit which would affect the effective tax rate if recognized.

The Company includes interest and penalties arising from the underpayment of income taxes in the statements of operations in the provision for income taxes. As of June 30, 2016, the Company had no accrued interest or penalties related to uncertain tax positions.

The Company files an income tax return in the U.S. federal jurisdiction and the state of California. With few exceptions, the Company is no longer subject to U.S. federal, state, and local, or non-U.S. income tax examinations by tax authorities for years before 2008.

At June 30, 2016, the Company had net operating loss carry forwards of approximately $6,300,000 through 2034.No tax benefit has been reported in the June 30, 2016 financial statements since the potential tax benefit is offset by a valuation allowance of the same amount.

Page 13

Due to the change in ownership provisions of the Tax Reform Act of 1986, net operating loss carry forwards for Federal income tax reporting purposes are subject to annual limitations. Should a change in ownership occur, net operating loss carry forwards may be limited as to use in future years.

Recently Issued Accounting Pronouncements

The Company has evaluated recent accounting pronouncements and their adoption has not had or is not expected to have a material impact on the Company's financial position, or statements.
