Significant Accounting Policies	2. Significant Accounting Policies *Basis of Presentation and Use of Estimates* The Company prepares its financial statements in conformity with accounting principles generally accepted in the United States of America which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Some of the more significant estimates required to be made by management include valuation of shares issued for services, recognition of income for work completed and unbilled to customers, the allowance for doubtful accounts, and the valuation of License Agreements. Actual results could differ from those estimates. The Company believes that funds generated from operations, together with existing cash and cash infusions by stockholders, will be sufficient to finance its operations for the next twelve months. The Company expects to seek additional capital to cover any working capital needs and its contractual obligations, and to fund growth initiatives in its identified markets. However, there can be no assurance that any new debt or equity financing arrangement will be available to the Company when needed on acceptable terms, if at all. The continued operations of the Company are dependent on its ability to raise funds, collect accounts receivable, and receive revenues. *Cash* The Company continually monitors its positions with, and the credit quality of, the financial institutions it invests with. From time to time, however, the Company briefly maintains balances in operating accounts in excess of federally insured limits. *Accounts Receivable* Receivables are stated at the amount management expects to collect from outstanding balances. Management provides for probable uncollectible amounts through a charge to earnings and a credit to a valuation allowance based on its assessment of the current status of individual accounts. At December 31, 2018, an allowance for doubtful accounts was made totaling $56,204 to provide for the possibility of a revenue shortfall from the project in Modoc County, and is reflected in the accounts receivable balance on the balance sheet in the accompanying financial statements. In 2017, this allowance was $63,270. *Revenue Recognition* The Company’s revenue is recognized when the Company satisfies its performance obligation(s) under the contract (either implicit or explicit) by transferring the promised product or service to its customer either when (or as) its customer obtains control of the product or service. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation. The majority of the Company’s contracts have a single performance obligation, as the promise to transfer products or services is not separately identifiable from other promises in the contract and, therefore, not distinct. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products or providing services. As such, revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales and other taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. The Company’s performance obligations under its engine business are generally satisfied as over time. Revenue from products or services transferred to its customer over time accounted for approximately 4.5% and 9.6% of revenue for the years ended December 31, 2018 and 2017, respectively. Revenue under this contract is generally recognized over time using an input measure based upon the proportion of actual costs incurred to estimated total project costs, which is a method used to best depict the Company’s performance to date under the terms of the contract. Accounting for over time contracts involves the use of various techniques to estimate total revenue and costs. The Company estimates profit on such contracts as the difference between total estimated revenue and expected costs to complete a contract and recognizes that profit over the life of the contract. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include, among other things, labor productivity, costs and availability of materials. The nature of these long-term agreements may give rise to several types of variable consideration, such as claims, awards and incentive fees. These amounts of variable consideration are not expected to be significant. Additionally, contract estimates may include additional revenue for submitted contract modifications if there exists and enforceable right to the modification, the amount can be reasonably estimated and its realization is probable. These estimates are based on historical collection experience, anticipated performance, and the Company’s best judgment at the time. These amounts are generally included in the contract’s transaction price and are allocated over the remaining performance obligations. Changes in judgments on these above estimates could impact the timing and amount of revenue recognized with a resulting impact on the timing and amount of associated income. The Company may receive payments from customers based upon contractual billing schedules; accounts receivable are recorded when the right to consideration becomes unconditional. In the event a contract loss becomes known, the entire amount of the estimated loss is recognized in the Statement of Operations. The majority of the Company’s revenue is from products and services transferred to customers at a point in time. It was approximately 95.5% and 90.1% of revenue for the years ended December 31, 2018 and 2017, respectively. The Company recognizes revenue at the point in time in which the customer obtains control of the product or service, which is generally when product title passes to the customer upon shipment. The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in contract assets or contract liabilities (deferred revenue) on the Company’s balance sheet. The Company records a contract asset when revenue is recognized prior to invoicing, or contract liabilities when revenue is recognized subsequent to invoicing. Contract liabilities additionally include customer advances or prepayments. The Company had unbilled receivables (contract assets) of $146,000 and $62,212 at December 31, 2018 and 2017, respectively. Costs in excess of billings and billings in excess of costs associated with over time contracts were not significant at December 31, 2018 or 2017. There was no revenue recognized during the year ended December 31, 2018 and 2017 that was included in contract liabilities at the beginning of the period. On December 31, 2018, the Company had no remaining performance obligations. *Fixed Assets* Fixed assets are being depreciated on the straight line basis over a period of five years. Accumulated depreciation at December 31, 2018 and 2017 was $20,091 and $12,303, respectively. *License Agreements* At the time of the Merger, Sustainable had a series of agreements including an exclusive, renewable 20-year engine technology license agreement (the “Agreement”) with a third party licensor that had developed engines capable of converting heat into other forms of energy. The agreements were assigned to the Company. Under the terms of the Agreement, it could be cancelled by the Company during the term once the patents upon which it was based expired. The newer of two patents expired in August of 2017, and the Company elected at that time to exercise its right to cancel the Agreement. The third party licensor had been classified in 2010 as dissolved by the Delaware Division of Corporations, and similarly by the Arizona Corporation Commission, and has not reinstated its charters. Despite this status, during July, 2017, the Company received a demand letter from the principal of that firm claiming that an aggregate total of $1,104,367 was due the firm under the Agreement, and to the principal for consulting work. The Company and its counsel believe that the claims are without merit and would vigorously defend any potential lawsuit. The Company believes it has no outstanding obligation to either party, and took the remaining unamortized asset value of the Agreement, $20,307, as a charge against earnings in the third quarter of 2017. Subsequently, in December, 2017, the Company entered into an intellectual property license agreement with Thermal Tech Holdings, LLC, a Delaware limited liability company (“TTH”). TTH is an entity owned equally by two entities affiliated, respectively, with two officers and directors of the Company, who also serve in management positions with TTH. TTH is the owner of certain patent applications as well as the inventions relating to the Company’s proprietary engine technology (the “Licensed Patents and Technical Information”). The Licensed Patents and Technical Information were developed by an independent non-profit research institute (the “Contractor”). All work done by the Contractor for the patent applications and inventions licensed thereunder was paid for by TTH in order that TTH, rather than the Company, would be at risk if the research, development, engineering and design work were of little or no value. Furthermore, the work performed by the Contractor for TTH was confidential for competitive business reasons. The Patent License grants the Company a worldwide non-exclusive license to use the Technical Information to make, use or sell any products and/or services which would be covered by these specific Licensed Patents. However, TTH may not license any Licensed Patents and Technical Information to any competitive entity, or to any other entity without the prior written consent of the Company. The Company will pay TTH a royalty equal to five (5%) percent of the Net Revenue (as defined) of all Licensed Products covered by a Licensed Patent sold by the Company and its affiliates, as well as an initial license fee of $135,000, of which $94,500 has been paid. In March of 2019, the Company completed the license fee with a payment of the remaining $40,500. The Patent License will terminate upon the expiration of all Licensed Patents. The Company may terminate the agreement on ninety (90) days’ prior written notice. TTH may terminate the agreement on ninety (90) days’ prior written notice for uncured defaults (as defined). *Income Taxes* The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by the tax authorities. Management has analyzed the Company’s tax positions, and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years (2015 - 2017). *Basic and Diluted Net (Loss) per Share* The Company computes income (loss) per share in accordance with “ASC-260”, “Earnings per Share” which requires presentation of both basic and diluted income (loss) per share on the face of the statement of operations. Basic (loss) per share is computed by dividing net income available to common shareholders by the weighted average number of outstanding common shares during the period. Diluted (loss) per share gives effect to all dilutive potential common shares outstanding during the period. Dilutive income (loss) per share excludes all potential common shares if their effect is anti-dilutive. For 2018 and 2017, basic (loss) and diluted (loss) per share were the same. The warrants outstanding at December 31, 2018 are antidilutive. *Recent Accounting Pronouncements* In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (Topic 606). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 is effective for the Company’s 2018 calendar year. The Company adopted this standard on January 1, 2018, and it has had no material effect on the Company’s financial statements. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-02: “Leases” (“ASU 2016-02”). ASU 2016-02 creates new accounting and reporting guidelines for leasing arrangements. The new standard will require organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease primarily will depend on its classification as a finance or operating lease. The standard will also require new disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The new standard is effective for the Company’s 2019 calendar year, with early application permitted. The Company has evaluated the impact of ASU 2016-02 on its consolidated financial statements, and management does not expect the standard to have a material impact. On June 20, 2018, FASB issued Accounting Standards Update No. 2018-07, “Compensation - Stock Compensation” (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”). ASU 2018-07 is intended to reduce cost and complexity and to improve financial reporting for share-based payments issued to non-employees. This ASU expands the scope of ASC Topic 718, “Compensation - Stock Compensation”, which currently only includes share-based payments issued to employees, to also include share-based payments issued to non-employees for goods and services. Consequently, the accounting for share-based payments to non-employees and employees will be substantially aligned. ASU 2018-07 supersedes ASC Subtopic 505-50, “Equity - Equity-Based Payments to Non-Employees”. The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect the adoption of this standard to have a material impact on its financial statements. All other accounting standards that have been issued or proposed by the FASB that do not require adoption until a future date are not expected to have a material impact on the financial statements upon adoption. *Subsequent Events* Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were available to be issued.

Recent Accounting Pronouncements

In May 2014, FASB issued ASU 2014-09, “Revenue from Contracts with Customers” (Topic 606). ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 is effective for the Company’s 2018 calendar year. The Company adopted this standard on January 1, 2018, and it has had no material effect on the Company’s financial statements.

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-02: “Leases” (“ASU 2016-02”). ASU 2016-02 creates new accounting and reporting guidelines for leasing arrangements. The new standard will require organizations that lease assets to recognize assets and liabilities on the balance sheet related to the rights and obligations created by those leases, regardless of whether they are classified as finance or operating leases. Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash flows arising from a lease primarily will depend on its classification as a finance or operating lease. The standard will also require new disclosures to help financial statement users better understand the amount, timing, and uncertainty of cash flows arising from leases. The new standard is effective for the Company’s 2019 calendar year, with early application permitted. The Company has evaluated the impact of ASU 2016-02 on its consolidated financial statements, and management does not expect the standard to have a material impact.

On June 20, 2018, FASB issued Accounting Standards Update No. 2018-07, “Compensation - Stock Compensation” (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”).

The amendments in this ASU are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect the adoption of this standard to have a material impact on its financial statements.

All other accounting standards that have been issued or proposed by the FASB that do not require adoption until a future date are not expected to have a material impact on the financial statements upon adoption.

Subsequent Events

Management has evaluated subsequent events for disclosure and/or recognition in the financial statements through the date that the financial statements were available to be issued.
