Accounting Policies [Abstract] |
Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for annual financial reporting. All amounts referred to in the notes to the consolidated financial statements are presented in euros (EUR) and have been rounded to the nearest thousand, unless otherwise stated. Substantially all of the Company’s operations are conducted in EUR and the current reporting currency is the same as the functional currency. At the end of the second quarter of 2024, the Company determined that it no longer qualified as a foreign private issuer under the SEC rules. As a result, beginning January 1, 2025, the Company became subject to the reporting requirements applicable to U.S. domestic issuers. Accordingly, these consolidated financial statements have been prepared in accordance with U.S. GAAP, and the transition from International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”), has been applied retrospectively to all periods presented.
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Significant estimates include assumptions about cash flow and fair value assumptions associated with measurements of convertible notes payable carried at fair value, valuation of inventory; the valuation and recognition of stock-based compensation expense; valuation allowance for deferred tax assets; and borrowing rate consideration for right-of-use (“ROU”) lease assets including related lease liability and useful life of fixed assets.
Cash and Cash Equivalents, Policy [Policy Text Block] | Cash For financial statement purposes, the Company considers all cash in the bank to be cash.
Lessee, Leases [Policy Text Block] | Leases Upon transition under ASU 2016-02, the Company elected the suite of practical expedients as a package applied to all of its leases, including (i) not reassessing whether any expired or existing contracts are or contain leases, (ii) not reassessing the lease classification for any expired or existing leases, and (iii) not reassessing initial direct costs for any existing leases. For new leases, the Company will determine if an arrangement is or contains a lease at inception. Leases are included as ROU assets within other assets and ROU liabilities within accrued expenses and other liabilities and within other long-term liabilities on the Company’s consolidated balance sheets. Additionally, the Company elected the exemption available under ASC 842-20-25-2 for short term lease agreements and recognizes lease payments on a straight line basis. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate. The Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The ROU asset also includes any lease payments made and excludes lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term. See Note 8 for more complete details on balances as of the reporting periods presented herein.
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentrations of Credit Risk The Company’s financial instruments that are exposed to a concentration of credit risk are cash and accounts receivable. Generally, the Company’s cash and cash equivalents are in checking accounts.
Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment Property and equipment are stated at cost. When retired or otherwise disposed, the related carrying value and accumulated depreciation are removed from the respective accounts and the net difference less any amount realized from disposition, is reflected in earnings. For consolidated financial statement purposes, property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives of 5 to 7 years. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. The Company examines the possibility of decreases in the value of fixed assets when events or changes in circumstances reflect the fact that their recorded value may not be recoverable. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The amount of impairment is measured as the difference between the asset’s estimated fair value and its book value.
Fair Value Measurement, Policy [Policy Text Block] | Fair Value of Assets and Liabilities Fair value is the price that would be received from the sale of an asset or paid to transfer a liability (i.e., an exit price) in the principal or most advantageous market in an orderly transaction between market participants. In determining fair value, the accounting standards have established a three-level hierarchy that distinguishes between (i) market data obtained or developed from independent sources (i.e., observable data inputs) and (ii) a reporting entity’s own data and assumptions that market participants would use in pricing an asset or liability (i.e., unobservable data inputs). Financial assets and financial liabilities measured and reported at fair value are classified in one of the following categories, in order of priority of observability and objectivity of pricing inputs: ● Level 1 – Fair value based on quoted prices in active markets for identical assets or liabilities; ● Level 2 – Fair value based on significant directly observable data (other than Level 1 quoted prices) or significant indirectly observable data through corroboration with observable market data. Inputs would normally be (i) quoted prices in active markets for similar assets or liabilities, (ii) quoted prices in inactive markets for identical or similar assets or liabilities or (iii) information derived from or corroborated by observable market data; ● Level 3 – Fair value based on prices or valuation techniques that require significant unobservable data inputs. Inputs would normally be a reporting entity’s own data and judgments about assumptions that market participants would use in pricing the asset or liability. The fair value measurement level for an asset or liability is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques should maximize the use of observable inputs and minimize the use of unobservable inputs. The Company utilizes a binomial lattice option pricing model to estimate the fair value of options, warrants, beneficial conversion features and other Level 3 financial assets and liabilities. The Company believes that the binomial lattice model results in the best estimate of fair value because it embodies all of the requisite assumptions (including the underlying price, exercise price, term, volatility, and risk-free interest-rate) necessary to fairly value these instruments and, unlike less sophisticated models like the Black-Scholes model, it also accommodates assumptions regarding investor exercise behavior and other market conditions that market participants would likely consider in negotiating the transfer of such an instruments.
Share-Based Payment Arrangement [Policy Text Block] | Stock-Based Compensation The Company accounts for stock-based compensation to employees and nonemployees under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 718 “Compensation – Stock Compensation” using the fair value-based method. Under this method, compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. This guidance establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. The Company uses a binomial lattice pricing model to estimate the fair value of options and warrants granted.
Income Tax, Policy [Policy Text Block] | Income Taxes The Company follows Accounting Standards Codification subtopic 740-10, Income Taxes (“ASC 740-10”) for recording the provision for income taxes. Deferred tax assets and liabilities are computed based upon the difference between the financial statement and income tax basis of assets and liabilities using the enacted marginal tax rate applicable when the related asset or liability is expected to be realized or settled. Deferred income tax expenses or benefits are based on the changes in the asset or liability during each period. If available evidence suggests that it is more likely than not that some portion or all of the deferred tax assets will not be realized, a valuation allowance is required to reduce the deferred tax assets to the amount that is more likely than not to be realized. Future changes in such valuation allowance are included in the provision for deferred income taxes in the period of change. Deferred income taxes may arise from temporary differences resulting from income and expense items reported for financial accounting and tax purposes in different periods. Deferred taxes are classified as current or non-current, depending on the classification of assets and liabilities to which they relate. Deferred taxes arising from temporary differences that are not related to an asset or liability are classified as current or non-current depending on the periods in which the temporary differences are expected to reverse and are considered immaterial. No income tax has been provisioned for the years ended December 31, 2024 and 2023, since the Company has sustained losses historically and has substantial net operating loss carryforwards for both periods. Due to the uncertainty of the utilization and recoverability of the loss carry-forwards and other deferred tax assets, management has determined a full valuation allowance for the deferred tax assets, since it is more likely than not that the deferred tax assets will not be realizable.
Fair Value of Financial Instruments, Policy [Policy Text Block] | Recurring Fair Value Measurements The carrying value of the Company’s financial assets and financial liabilities is their cost, which may differ from fair value. The carrying value of cash held as demand deposits, accounts payable, and accrued liabilities approximated their fair value.
Earnings Per Share, Policy [Policy Text Block] | Net Income / (Loss) per Share Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. During the year ended December 31, 2023 the Company reported a net loss and excluded all outstanding stock options and other dilutive securities from the calculation of diluted net loss per common share because inclusion of these securities would have been anti-dilutive. As of December 31, 2024 the Company reported net income and accordingly, included outstanding stock options and the shares indexed to the Convertible Notes Payable at Fair Value of 33,689 and 15,771,230 respectively.
Segment Reporting, Policy [Policy Text Block] | Business Segments The Company uses the “management approach” to identify its reportable segments. The management approach designates the internal organization used by management for making operating decisions and assessing performance as the basis for identifying the Company’s reportable segments. Using the management approach, the Company determined that it has one operating segment, solar retrofitting of vehicles.
Error Correction [Policy Text Block] | Correction of an Error in Research and Development Expenses During the preparation of the financial statements for the year ended December 31, 2024, the Company identified an error resulting from the misclassification of certain costs associated with research and development activities. Specifically, amounts incurred for services provided in fiscal year 2023 were erroneously recorded within fiscal year 2024. The error has been corrected retrospectively by reclassifying the affected amounts to the proper fiscal year. As a result, 2023 Research and Development expenses which had been reported at $15,783 was restated to $16,136 and Accounts payable and accrued expenses which had been reported at $55,798 was restated to $56,576. The accumulated deficit was restated as a result of the foregoing changes from $385,677 to $386,454.
New Accounting Pronouncements, Policy [Policy Text Block] | Recently Issued Pronouncements In March 2024, the FASB issued ASU No. 2024-01, “Compensation—Stock Compensation (Topic 718): Scope Applications of Profits Interests and Similar Awards” (“ASU 2024-01”). ASU 2024-01 adds an example to Topic 718 which illustrates how to apply the scope guidance to determine whether profits interests and similar awards should be accounted for as share-based payment arrangements under Topic 718 or under other U.S. GAAP. ASU 2024-01 is effective for annual periods beginning after December 15, 2025, although early adoption is permitted. Upon adoption, ASU 2024-01 is not expected to have an impact on the Company’s consolidated financial statements. In March 2024, the FASB issued ASU No 2024-02, “Codification Improvements - Amendments to Remove References to the Concepts Statements” (“ASU 2024-02”). ASU 2024-02 removes references to various Concepts Statements. In most instances, the references are extraneous and not required to understand or apply the guidance. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2024-02 can be applied prospectively or retrospectively. Upon adoption, ASU 2024-01 is not expected to have an impact on the Company’s consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40).” This standard requires disclosure of specific information about costs and expenses and becomes effective January 1, 2027. We are currently evaluating the impact of this standard on our consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-04, “Debt - Debt with Conversions and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments” (“ASU 2024-04”). ASU 2024-04 clarifies the requirements for determining whether certain settlements of convertible debt instruments, including convertible debt instruments with cash conversion features or convertible debt instruments that are not currently convertible, should be accounted for as an induced conversion. The requirements of ASU 2024-04 are effective for the Company for fiscal years beginning after December 15, 2025, and interim periods within those periods. We are currently evaluating the impact of this standard on our consolidated financial statements and related disclosures. Recently Adopted Pronouncements In November 2023, the FASB issued Accounting Standards Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires public entities to disclose information about their reportable segments’ significant expenses and other segment items on an interim and annual basis. Public entities with a single reportable segment are required to apply the disclosure requirements in ASU 2023-07, as well as all existing segment disclosures and reconciliation requirements in ASC 280, on an interim and annual basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this standard in the year ended December 31, 2024. The adoption did not have a material effect on the Company’s consolidated financial statements. In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted this standard in the year ended December 31, 2024. The adoption did not have a material effect on the Company’s consolidated financial statements. No other new accounting pronouncements were issued or became effective in the period that had, or are expected to have, a material impact on our consolidated Financial Statements.
