Significant Accounting Policies [Text Block]	Note 2 Summary of Significant Accounting Policies Use of Estimates The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. Management evaluates its estimates and related assumptions regularly, including those related to the value of property, plant and equipment, income taxes including valuation allowances for net deferred tax assets, share-based compensation and fair value measurements. Changes in facts and circumstances or additional information may may Concentrations of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents. We maintain cash balances with a single financial institution, which may not Cash Equivalents We consider all highly liquid investments with an original maturity of three Investment Securities We define investment securities as investments in marketable securities that can be readily converted to cash. We determine the appropriate classification of investment securities at the time of purchase and reevaluate such classification at each balance sheet date. Investment securities are initially recorded at cost and remeasured to fair value, with changes presented in other income in our Consolidated Statements of Operations. Property, Plant and Equipment Generally, we begin to capitalize the costs of our development projects once construction of the individual project is probable. This assessment includes the following criteria: • funding for design and permitting has been identified and is expected in the near-term; • key vendors for development activities have been identified, and we expect to engage them at commercially reasonable terms; • we have committed to commencing development activities; • regulatory approval is probable; • construction financing is expected to be available at the time of a final investment decision (“FID”); • prospective customers have been identified and the FID is probable; and • receipt of customary local tax incentives, as needed for project viability, is probable. Prior to meeting the criteria above, costs associated with a project are expensed as incurred. Expenditures for normal repairs and maintenance are expensed as incurred. When assets are retired or disposed, the cost and accumulated depreciation are eliminated from the accounts and any gain or loss is reflected in our Consolidated Statements of Operations. Property, plant and equipment is carried at historical cost and depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are depreciated over the lesser of the economic life of the leasehold improvement or the term of the lease, without regard to extension/renewal rights. Management tests property, plant and equipment for impairment whenever events or changes in circumstances have indicated that the carrying amount of property, plant and equipment might not not Warrants The Company determines the accounting classification of warrants that are issued, as either liability or equity, by first 480 Distinguishing Liabilities from Equity 480” 815 40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock 815 40” 480, may If warrants do not 480, 815 40, may not 815 40, 815 40 no Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Hierarchy Levels 1, 2 3 1 2 1 3 not Note 4 Investment Securities Note 9 Preferred Stock and Common Stock Warrants Treasury Stock Treasury stock is recorded at cost. Issuance of treasury stock is accounted for on a weighted average cost basis. Differences between the cost of treasury stock and the re-issuance proceeds are charged to additional paid-in capital. Net Loss Per Share Net loss per share (“EPS”) is computed in accordance with GAAP. Basic EPS excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if the potential common shares had been issued and were dilutive. The dilutive effect of unvested stock and warrants is calculated using the treasury-stock method and the dilutive effect of convertible securities is calculated using the if-converted method. Basic and diluted EPS for all periods presented are the same since the effect of our potentially dilutive securities are anti-dilutive to our net loss per share, as disclosed in Note 10 Net Loss Per Share Attributable to Common Stockholders . Share-based Compensation We recognize share-based compensation at fair value on the date of grant. The fair value is recognized as expense (net of any capitalization) over the requisite service period. For equity-classified share-based compensation awards, compensation cost is recognized based on the grant-date fair value using the quoted market price of our common stock and not Income Taxes Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements. Deferred tax assets and liabilities are included in the Consolidated Financial Statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the current period’s provision for income taxes. A valuation allowance is recorded to reduce the carrying value of our net deferred tax assets when it is more likely than not not not Emerging Growth Company and Smaller Reporting Company The Company is an “emerging growth company,” as defined in Section 2 1933, 2012 may not not not 404 2002, not may no Further, section 102 1 not Additionally, under Rule 12b 2 1934, second $250 may not

Significant Accounting Policies

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. Management evaluates its estimates and related assumptions regularly, including those related to the value of property, plant and equipment, income taxes including valuation allowances for net deferred tax assets, share-based compensation and fair value measurements. Changes in facts and circumstances or additional information may may
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents. We maintain cash balances with a single financial institution, which may not
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash Equivalents We consider all highly liquid investments with an original maturity of three
Investment, Policy [Policy Text Block]	Investment Securities We define investment securities as investments in marketable securities that can be readily converted to cash. We determine the appropriate classification of investment securities at the time of purchase and reevaluate such classification at each balance sheet date. Investment securities are initially recorded at cost and remeasured to fair value, with changes presented in other income in our Consolidated Statements of Operations.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment Generally, we begin to capitalize the costs of our development projects once construction of the individual project is probable. This assessment includes the following criteria: • funding for design and permitting has been identified and is expected in the near-term; • key vendors for development activities have been identified, and we expect to engage them at commercially reasonable terms; • we have committed to commencing development activities; • regulatory approval is probable; • construction financing is expected to be available at the time of a final investment decision (“FID”); • prospective customers have been identified and the FID is probable; and • receipt of customary local tax incentives, as needed for project viability, is probable. Prior to meeting the criteria above, costs associated with a project are expensed as incurred. Expenditures for normal repairs and maintenance are expensed as incurred. When assets are retired or disposed, the cost and accumulated depreciation are eliminated from the accounts and any gain or loss is reflected in our Consolidated Statements of Operations. Property, plant and equipment is carried at historical cost and depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are depreciated over the lesser of the economic life of the leasehold improvement or the term of the lease, without regard to extension/renewal rights. Management tests property, plant and equipment for impairment whenever events or changes in circumstances have indicated that the carrying amount of property, plant and equipment might not not

Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Hierarchy Levels 1, 2 3 1 2 1 3 not Note 4 Investment Securities Note 9 Preferred Stock and Common Stock Warrants
Treasury Stock [Policy Text Block]	Treasury Stock Treasury stock is recorded at cost. Issuance of treasury stock is accounted for on a weighted average cost basis. Differences between the cost of treasury stock and the re-issuance proceeds are charged to additional paid-in capital.
Earnings Per Share, Policy [Policy Text Block]	Net Loss Per Share Net loss per share (“EPS”) is computed in accordance with GAAP. Basic EPS excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if the potential common shares had been issued and were dilutive. The dilutive effect of unvested stock and warrants is calculated using the treasury-stock method and the dilutive effect of convertible securities is calculated using the if-converted method. Basic and diluted EPS for all periods presented are the same since the effect of our potentially dilutive securities are anti-dilutive to our net loss per share, as disclosed in Note 10 Net Loss Per Share Attributable to Common Stockholders .
Share-based Payment Arrangement [Policy Text Block]	Share-based Compensation We recognize share-based compensation at fair value on the date of grant. The fair value is recognized as expense (net of any capitalization) over the requisite service period. For equity-classified share-based compensation awards, compensation cost is recognized based on the grant-date fair value using the quoted market price of our common stock and not
Income Tax, Policy [Policy Text Block]	Income Taxes Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements. Deferred tax assets and liabilities are included in the Consolidated Financial Statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the current period’s provision for income taxes. A valuation allowance is recorded to reduce the carrying value of our net deferred tax assets when it is more likely than not not not
