| Accounting Policies [Abstract] | ||||||||||||||
| Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation The preparation of financial statements in conformity with US GAAP requires management to make certain 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. |
|||||||||||||
| Cash and Cash Equivalents, Policy [Policy Text Block] | 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. |
|||||||||||||
| Trade and Other Accounts Receivable, Policy [Policy Text Block] | Accounts Receivable Trade accounts receivable are stated net of an allowance for doubtful accounts. The Company performs ongoing credit evaluations of its customers’ financial condition. In limited instances, the Company may require an upfront deposit and, in most cases, the Company does charge interest on past due amounts. Management estimates the allowance for doubtful accounts based on review and analysis of specific customer balances that may not be collectible, customer payment history and any other customer-specific information that may impact the evaluation of the specific customer’s credit. Accounts are considered for write-off when they become past due and when it is determined that the probability of collection is remote. The allowance for doubtful accounts was $15,145 and $24,775 at December 31, 2015 and 2014, respectively. |
|||||||||||||
| Inventory, Policy [Policy Text Block] | Inventories Inventories are stated at the lower of cost (first in, first out method) or market value. Inventory quantities on hand are reviewed regularly and a write-down for excess and obsolete inventory is recorded based primarily on an estimated forecast of product demand, market conditions and anticipated production requirements in the near future. There was a $4,274 and $40,703 reserve for excess and obsolete inventory at December 31, 2015 and 2014, respectively, related to component parts not anticipated to have a future use. |
|||||||||||||
| Property, Plant and Equipment, Policy [Policy Text Block] | Property and Equipment Property and equipment are stated at historical cost less accumulated depreciation and amortization. Major additions and improvements are capitalized while maintenance and repairs that do not improve or extend the useful life of the respective asset are expensed. Depreciation and amortization of property and equipment is computed using the straight-line method over their estimated useful lives. Leasehold improvements are amortized over the shorter of the life of the asset or the related leases. Estimated useful lives of the principal classes of assets are as follows:

| Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block] | Intangible Assets The Company’s intangible assets are primarily composed of patents, which are recorded at cost. The Company capitalizes third party legal costs and filing fees, if any, associated with obtaining patents or other intangible assets. Once the intangible asset has been placed in service, the Company amortizes these costs over the shorter of the asset’s legal life, generally 20 years, or its estimated economic life using the straight-line method. |
|||||||||||||
| Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block] | Impairment of Long-Lived Assets The long-lived assets held and used by the Company are reviewed for impairment no less frequently than annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In the event that facts and circumstances indicate that the cost of any long-lived assets may be impaired, an evaluation of recoverability is performed. Management has determined that there was an impairment in the value of long-lived assets in the amount of $199,546 during the year ended December 31, 2015. There were no impairments in the value of long-lived assets in the year ended December 31, 2014. |
|||||||||||||
| 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 at the measurement date. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree that the inputs are observable. The categorization of financial assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable and accounts payable. As of the balance sheet dates, the estimated fair values of the financial instruments were not materially different from their carrying values as presented on the balance sheets. This is primarily attributed to the short-term maturities of these instruments. The Company did not identify any other non-recurring assets and liabilities that are required to be presented in the balance sheets at fair value. |

| Revenue Recognition, Policy [Policy Text Block] | Revenue Recognition Revenue from product sales is recognized when the risks of loss and title pass to the customer, as specified in (1) the respective sales agreements and (2) other revenue recognition criteria as prescribed by Staff Accounting Bulletin (“SAB”) No. 101 (SAB 101), “Revenue Recognition in Financial Statements,” as amended by SAB No. 104, “Revenue Recognition”. The Company generally sells its products FOB shipping and recognizes revenue when products are shipped. In prior years, the Company received payments from government entities in the form of government grants. Government grants are agreements that generally provide the Company with cost reimbursement for certain types of research and development activities over a contractually defined period. Revenues from government grants are recognized in the period during which the Company incurs the related costs, provided that the Company has incurred the cost in accordance with the specifications and work plans determined between the Company and the government entity. Costs incurred related to the grants are recorded as grant research and development costs. At December 31, 2014, the Company had recognized all grant revenues related to the ARPA-E grant and no grant revenue was recognized in the year ended December 31, 2015. Grant receivables were $132,227 at December 31, 2014 and were included in accounts receivable. |
|||||||||||||
| Standard Product Warranty, Policy [Policy Text Block] | Product Warranties The Company generally provides a ten year limited warranty on its products. Accruals for product warranties are estimated based upon limited historical warranty experience, engineering experience and judgment, and third party assessments of the reliability of the Company’s 30kW products. Accruals for product warranties are recorded in cost of revenues at the time revenue is recognized in order to match revenues with related expenses. The Company assesses the adequacy of its estimated warranty liability quarterly and adjusts the reserve, included in accrued expenses, as necessary. Although any such adjustments were not material in the years ended December 31, 2015 and 2014, any such adjustments could be material in the future if estimates differ significantly from actual warranty experience. |
|||||||||||||
| Research and Development Expense, Policy [Policy Text Block] | Research and Development Grant research and development are costs incurred solely related to grant revenues, and are classified as a line item under cost of revenues. Other research and development costs are presented as a line item under operating expenses and are expensed as incurred. Total research and development costs incurred during the years ended December 31, 2015 and 2014 amounted to $5,521,390 and $2,983,648, respectively, of which $643,421 was included in cost of revenues in the year ended December 31, 2014. |
|||||||||||||
| Income Tax, Policy [Policy Text Block] | Income Taxes The Company accounts for income taxes using an asset and liability approach which allows for the recognition and measurement of deferred tax assets based upon the likelihood of realization of tax benefits in future years. Under the asset and liability approach, deferred taxes are provided for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided for deferred tax assets if it is more likely than not these items will either expire before the Company is able to realize their benefits, or that future deductibility is uncertain. At December 31, 2015 and 2014, the Company has established a full reserve against all deferred tax assets. Tax benefits from an uncertain tax position are recognized 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. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate resolution. |
|||||||||||||
| Earnings Per Share, Policy [Policy Text Block] | Net Loss Per Share The Company applies Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 260, “Earnings per Share.” Basic earnings (loss) per share is computed by dividing earnings (loss) available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings (loss) per share is computed similar to basic earnings (loss) per share except that the denominator is increased to include additional common shares available upon exercise of stock options and warrants using the treasury stock method. In periods with a net loss, no common share equivalents are included because their effect would be anti-dilutive. At December 31, 2015 and 2014, potentially dilutive shares outstanding amounted to 2,846,325 and 2,932,155, respectively. |
|||||||||||||
| Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock Based Compensation The Company applies FASB ASC 718, “Stock Compensation,” when recording stock based compensation. The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option valuation model. The Company uses a Monte Carlo simulation pricing model to determine the fair value of performance stock units (“PSUs”). A typical Monte Carlo exercise simulates a distribution of stock prices to yield an expected distribution of stock prices during and at the end of the performance period. The simulations are repeated many times in order to derive a probabilistic assessment of stock performance. The stock-paths are simulated using assumptions which include expected stock price volatility and risk-free interest rate. The Company accounts for stock issued to non-employees in accordance with the provisions of FASB ASC 505-50 “Equity Based Payments to Non-Employees.” FASB ASC 505-50 states that equity instruments that are issued in exchange for the receipt of goods or services should be measured at the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. The measurement date occurs as of the earlier of (a) the date at which a performance commitment is reached or (b) absent a performance commitment, the date at which the performance necessary to earn the equity instruments is complete (that is, the vesting date). The Company issues common stock upon exercise of equity awards and warrants. |
|||||||||||||
| Presentation of Sales Taxes Policy [Policy Text Block] | Presentation of Sales Taxes Certain states impose a sales tax on the Company’s sales to nonexempt customers. The Company collects that sales tax from customers and remits the entire amount to the states. The Company’s accounting policy is to exclude the tax collected and remitted to the states from revenues and cost of revenues. |
|||||||||||||
| Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company maintains its cash with a major financial institution located in the United States. Balances are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company maintains balances in excess of federally insured limits. The Company has not experienced losses in such accounts and believes it is not exposed to significant credit risk regarding its cash and cash equivalents. The Company encounters a certain amount of risk as a result of a concentration of revenue from a few significant customers. Credit is extended to customers based on an evaluation of their financial condition. In limited instances, the Company may require an upfront deposit and, in most cases, the Company does charge interest on past due amounts. The Company performs ongoing credit evaluations of its customers and records an allowance for potential bad debts based on available information. The Company had revenue from four customers that accounted for 66% of net revenue for the year ended December 31, 2015, and from a government entity and three customers that accounted for 76% of net revenue for the year ended December 31, 2014. The Company had an accounts receivable balance from three customers that accounted for 66% of trade receivables at December 31, 2015, and three customers that accounted for 92% of trade receivables at December 31, 2014. |

| Reclassification, Policy [Policy Text Block] | Reclassifications Certain items in prior financial statements have been reclassified to conform to current year presentation. These changes did not impact total revenue, loss from operations or net loss. |

| New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers. ASU 2014-09 will require that companies recognize revenue based on the value of transferred goods or services as they occur in the contract. ASU 2014-09 also will require additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Based on the FASB’s Exposure Draft Update approved in July 2015, Revenue from Contracts With Customers (Topic 606): Deferral of the Effective Date, ASU 2014-09 is now effective for reporting periods beginning after December 15, 2017, with early adoption permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. Entities will be able to transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The adoption of ASU 2014-09 is not expected to have any impact on the Company’s financial statement presentation or disclosures. In August 2014, the FASB issued Accounting Standards Update No. 2014-15 (ASU 2014-15), Presentation of Financial Statements – Going Concern (Subtopic 205-10). ASU 2014-15 provides guidance as to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The adoption of ASU 2014-15 is not expected to have any impact on the Company’s financial statement presentation or disclosures. In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (ASU 2015-17), Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. ASU 2015-17 require that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted as of the beginning of an interim or annual reporting period. The adoption of ASU 2015-17 is not expected to have an impact the Company’s financial statement presentation or disclosures. Management does not believe that any other recently issued, but not yet effective, accounting standards, if adopted, will have a material effect on the financial statements. |
