Commitments and Contingencies Disclosure [Text Block] | Note 5 Commitments and Contingencies Warrants Warrants to subscribe for and purchase up to 3,000,000 shares of common stock at an exercise price of $0.052 per share were included under the terms of the DAF Credit Agreement. The warrants will be issued in amounts of 150,000 and 210,000 per month during the funding period. In the event that funding advances deviate from the planned schedule then warrants will be issued pro-rata at 1.2 warrants for every $1 of funding. Warrants granted under the terms of the DAF Credit Agreement as of September 30, 2022 total 2,814,000. The estimated value of the warrants granted monthly, with each advance, is calculated using the Black-Scholes option pricing model. The expected dividend yield is based on the average annual dividend yield as of the grant date. Expected volatility is based on the historical volatility of our stock. The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date. The expected life of the warrant is based on historical exercise behavior and expected future experience. The resulting estimated value of the warrant is used to proportionally allocate the fair value of the debt advance and the fair value of the warrants. On March 2, 2021, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with a single institutional investor in a private placement to sell (i) 23,500,000 shares of its common stock, (ii) pre-funded warrants to purchase up to an aggregate of 51,500,000 shares of its common stock, and (iii) warrants to purchase up to an aggregate of 82,500,000 shares of its common stock for gross proceeds of approximately $6,000,000. The combined purchase price for one share of common stock and associated Warrant is $0.08 and for one Pre-Funded Warrant and associated Warrant is $0.0799. The sale of the securities under the Purchase Agreement closed on March 5, 2021. The pre-funded warrants have an exercise price of $0.0001 per share, subject to adjustment as set forth in the pre-funded warrants for stock splits, stock dividends, recapitalizations and similar events. The pre-funded warrants will be exercisable immediately and may be exercised at any time until all of the pre-funded warrants are exercised in full. In addition, the Company agreed to issue to the placement agent (or its designees) warrants to purchase a number of shares equal to 8.0% of the aggregate number of shares and pre-funded warrant shares sold under the Purchase Agreement, or warrants to purchase an aggregate of up to 6,000,000 shares. The placement agent warrants generally will have the same terms as the warrants, except they will have an exercise price of $0.10.
