Loan #9 [Member] | Maine Technology Institute [Member]
Bank Debt (Details) [Line Items]
Variable interest rate with LIBOR, description		The first 27 months of this loan are interest-free with no interest accrual or required principal payments. Principal and interest payments at a fixed rate of 5% per annum are due quarterly over the final five years of the loan, beginning during the fourth quarter of 2022 and continuing through the third quarter of 2027. On June 30, 2021, we executed definitive agreements covering a second loan from the MTI (Loan #11) in the aggregate principal amount of $400,000, which proceeds were received in July 2021. The first 24 months of this loan are interest-free with no interest accrual or required principal payments. Beginning in July 2023, principal and interest payments are due quarterly at a fixed rate of 5% per annum based on a 5.5-year amortization schedule until December 2028.These credit facilities are unsecured and subordinated to our indebtedness to Gorham Savings Bank, which senior indebtedness is secured by mortgages and security interests with respect to substantially all of our assets. Failure to make timely payments of principal and interest, or otherwise to comply with the terms of the agreements with the MTI, would entitle the MTI to accelerate the maturity of such debt and demand repayment in full. These loans may be prepaid without penalty at any time.
