SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the 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 periods. The consolidated financial statements include estimates based on currently available information and management’s judgment as to the outcome of future conditions and circumstances. Significant estimates in these consolidated financial statements include, but are not limited to, measurement of revenue for contracts accounted for over time, accounts receivable reserves, inventory valuation, useful lives and impairment of long-lived assets, stock-based compensation and the valuation allowance related to the Company’s deferred tax assets. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the consolidated financial statements and actual results could differ from the estimates and assumptions.
Revenue Recognition	Revenue Recognition Revenue is recognized when (1) a contract with a customer exists, (2) performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer, (3) the transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer, (4) the transaction price is allocated to the performance obligations in the contract and (5) the Company satisfies its performance obligation. The Company satisfies its performance obligations and, therefore, recognizes revenue, either over time or at a point in time, which is when the customer has obtained control of the good or service. Revenue from the sale of the Company’s electric power systems under its Electrical Infrastructure segment is recognized either over time or at a point in time and substantially all of the Company’s revenue from the sale of power generation equipment under its Critical Power segment is recognized at a point in time. Certain sales of highly customized electrical equipment under the Company’s Electrical Infrastructure segment are recognized over time when such equipment has no alternative use and the Company has an enforceable right to payment for performance completed to date. The Company’s measure of progress for such contracts is evaluated under the input method based on direct labor hours incurred relative to the estimated total direct labor hours required in order to complete the project. Any anticipated losses on contracts are fully recognized in the period in which the losses become evident. Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services that are recognized as services are delivered. Contract Estimates Revenue from over time contracts is recognized proportionally over the term of the contract using an input method based on the proportion of labor hours incurred as compared to the total estimated labor hours for the fixed-fee contract performance obligations, which the Company considers the best available indicator of the pattern and timing in which contract performance obligations are fulfilled and control transfers to the customer. This percentage is multiplied by the contracted dollar amount of the project to determine the amount of revenue to recognize in an accounting period. There are situations where the number of hours to complete projects may exceed the original estimate as a result of an increase in project scope or unforeseen events. The related impact on income is recognized using the cumulative catch-up method, which the Company recognizes in the current period. Recognition of revenue on a contract requires estimates of the total labor hours at completion and the measurement of progress towards completion. Due to the long-term nature of many of the Company’s contracts, developing the estimated total labor hours at completion often requires judgment. Factors that must be considered in estimating the total labor hours to be completed include the nature and complexity of the work to be performed and the risk and impact of delayed performance. At the outset of each contract, the Company gauges its complexity and perceived risks and establish an estimated total number of labor hours at completion in line with these expectations. The Company follows a standard contract review process in which the Company reviews the progress and performance on its ongoing contracts at least quarterly.
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold also includes indirect labor and infrastructure cost related to the provision of field services.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured using inputs in one of the following three categories: Level 1 measurements are based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Valuation of these items does not entail a significant amount of judgment. Level 2 measurements are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or market data other than quoted prices that are observable for the assets or liabilities. Level 3 measurements are based on unobservable data that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. The Company’s financial instruments consist primarily of cash, accounts receivable, accounts payable and accrued liabilities. The carrying values of these financial instruments approximate their respective fair values due to the relatively short period of time between their origination and their expected realization or payment.
Concentrations	Concentrations The Company manages its accounts receivable credit risk by performing credit evaluations and monitoring amounts due from the Company’s customers. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable, as follows: At December 31, 2023, one customer represented approximately 23% of the Company’s accounts receivable. At December 31, 2022, three customers represented approximately 52%, 15% and 12% of the Company’s accounts receivable. For the year ended December 31, 2023, two customers represented approximately 42% and 20% of the Company’s revenue. For the year ended December 31, 2022, two customers represented approximately 43% and 10% of the Company’s revenue. As of December 31, 2023, one of the Company’s suppliers represented 18% of the Company’s accounts payable. As of December 31, 2022, three of the Company’s suppliers represented 38% of the Company’s accounts payable.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents in the consolidated financial statements. At December 31, 2023 and 2022, the Company did not have any cash equivalents. The Company has cash on deposits in several financial institutions which may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. As of December 31, 2023 and 2022, the Company had balances of $3,332 and $10,046 in excess of the FDIC insured limits, respectively. The Company reduces exposure to credit risk by maintaining cash deposits with major financial institutions. The Company has not experienced losses in such accounts and periodically evaluates the creditworthiness of its financial institutions. While the Company does not anticipate any losses, liquidity issues, or capital resource constraints arising from the bank failures during 2023, it cannot predict at this time to what extent it or its collaborators, employees, suppliers, and/or vendors could be negatively impacted by such bank failures and other macroeconomic and geopolitical events. The Company reduces its credit risk by placing its cash and cash equivalents with major financial institutions.
Accounts Receivable	Accounts Receivable On January 1, 2023, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” using a modified retrospective approach. The standard amends several aspects of the measurement of credit losses related to certain financial instruments, including the replacement of the existing incurred credit loss model and other models with the current expected credit losses model. The cumulative effect of adoption did not result in an adjustment to the allowance for credit loss, and accordingly, the Company’s accumulated deficit as of January 1, 2023. The Company accounts for trade receivables at original invoice amount less an estimate made for expected credit losses. The Company’s allowance for expected credit losses on accounts receivable reflects management’s estimate of credit losses over the remaining expected life of such assets, measured primarily using historical experience, as well as current conditions and forecasts that affect the collectability of the reported amount. There was $97 and $788 of reserves for expected credit losses as of December 31, 2023 and 2022, respectively.
Long-Lived Assets	Long-Lived Assets Depreciation and amortization for property and equipment is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property and equipment, are stated at cost less accumulated depreciation. Property and equipment are depreciated using the straight-line method, based on the estimated useful lives of the assets (buildings - 25 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences in the year the assets are ready for their intended use. The Company reviews all long-lived assets such as property and equipment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Recoverability of the assets that are held and used is measured by a comparison of the carrying amount of an asset to the estimated future cash flows expected to be generated by the asset or asset group. Impairment is measured by the amount by which the carrying value of the asset(s) exceed the fair value. There were no triggering events that would indicate impairment of long-lived assets at December 31, 2023 and 2022.
Leases	Leases The Company leases offices, facilities and equipment under operating and financing leases. The Company determines whether an arrangement is, or contains, a lease at contract inception. An arrangement contains a lease if the Company has the right to direct the use of and obtain substantially all of the economic benefits of an identified asset. Right-of-use assets and lease liabilities are recognized at lease commencement based on the present value of lease payments over the lease term. Leases with an initial term of 12 months or less are not recognized on the balance sheet and are recorded as short-term lease expense. The discount rate used to calculate present value is the Company’s incremental borrowing rate based on the lease term and the economic environment of the applicable country or region. Certain leases contain renewal options or options to terminate prior to lease expiration, which are included in the measurement of right-of-use assets and lease liabilities when it is reasonably certain they will be exercised. The Company has elected to account for lease and non-lease components as a single lease component for its offices and manufacturing facilities. Some lease arrangements include payments that are adjusted periodically based on actual charges incurred for common area maintenance, utilities, taxes and insurance, or changes in an index or rate referenced in the lease. The fixed portion of these payments is included in the measurement of right-of-use assets and lease liabilities at lease commencement, while the variable portion is recorded as variable lease expense. The Company’s leases typically do not contain material residual value guarantees or restrictive covenants.
Deferred Financing Costs	Deferred Financing Costs Certain legal, accounting and other third-party fees that are directly associated with equity financings are capitalized as deferred financing costs and included as a non-current asset on the balance sheet until such financings are consummated. After consummation of the equity financing, these costs will be recorded in the stockholders’ equity section of the consolidated balance sheets as a reduction of additional paid-in capital generated as a result of the offering, to the extent there are sufficient proceeds. Should the equity financing no longer be considered probable of being consummated, all deferred financing costs would be charged to operating expenses in the consolidated statements of operations.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. For the year ended December 31, 2023 and 2022, the Company operated solely in the United States. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred asset, net recorded as of December 31, 2023 and 2022 is realizable through future reversals of existing taxable temporary differences. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s consolidated financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits” below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations.
Unrecognized Tax Benefits	Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with FASB ASC “Income Taxes” (“ASC 740”). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the consolidated financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. The Company’s policy is to recognize interest and penalties related to income tax matters as interest expense.
Share-Based Payments	Share-Based Payments The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. The fair value of the award is measured on the grant date. The fair value amount is then recognized over the period during which services are required to be provided in exchange for the award, usually the vesting period, using the straight-line attribution approach. Upon the exercise of an award, the Company issues new shares of common stock out of its authorized shares. The Company computes the fair value of stock options granted using the Black-Scholes option pricing model. Award forfeitures are accounted for at the time of occurrence. The expected term used for options is the estimated period of time that options granted are expected to be outstanding. The Company utilizes the “simplified” method under ASC 718 to develop an estimate of the expected term of “plain vanilla” option grants. The Company does not currently have a sufficient trading history to fully support its historical volatility calculations. Accordingly, the Company is utilizing an expected volatility figure based on a review of the historical volatility on a blended basis of its own stock as well as of comparable entities over a period of time equivalent to the expected life of the instrument being valued. The risk-free interest rate was determined from the implied yields from U.S. Treasury zero-coupon bonds with a remaining term consistent with the expected term of the instrument being valued.
Inventory	Inventory Inventory is stated at the lower of cost or net realizable value using a weighted average cost method and includes the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or net realizable value. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory.
Income (Loss) Per Share	Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income or loss for the period by the weighted average number of vested common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income or loss for the period by the weighted average number of vested common shares outstanding, plus the number of additional common shares that would have been outstanding if the common share equivalents had been issued (computed using the treasury stock or if converted method), if dilutive.
Research and Development	Research and Development Research and development include expenses incurred by the Company’s Critical Power segment related to developing the Company’s mobile e-Boost EV charging solutions. Research and development expenses are charged to operations as incurred.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements There have been no recent accounting pronouncements not yet adopted by the Company which would have a material impact on the Company’s consolidated financial statements. Accounting Standards Update (“ASU”) 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement - Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation - Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” ASU 2023-03 amends the ASC for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 EITF Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. These updates were immediately effective and did not have a significant impact on the Company’s consolidated financial statements.
