Substantial Doubt about Going Concern [Text Block]	Note 2 - Liquidity As of June 30, 2024, we had $5,858,000 in cash and working capital of $5,047,000. For the six months ended June 30, 2024 we incurred a net loss of $2,119,000, financing activities provided $1,478,000 in net cash, and we used net cash of $1,610,000 in operating activities. We believe that our existing cash and cash equivalents will be sufficient to fund our operations and meet our working capital requirements through 2025.
