We produce commercial and industrial, natural-gas-fueled engine-driven, combined heat and power (CHP) products that reduce energy costs, decrease greenhouse gas emissions and alleviate congestion on the national power grid. Our products supply electric power or mechanical power for cooling, while heat from the engine is recovered and purposefully used at a facility.

For the three months ended March 31, 2024 we generated $248,216 in cash from operations and a net operating loss of $1,049,885, due to a decrease in Products revenue and gross margin, a decrease in Services gross margin percentage due to higher labor and material costs and an increase in operating expenses. Working capital at March 31, 2024 was $8,499,647, compared to $9,822,546 at December 31, 2023, a decrease of $1,322,899 and our accumulated deficit was $43,984,623. </span></div><div style="text-align:justify"><span><br/></span></div><div style="margin-bottom:6pt;text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As a result of the above factors, management has performed an analysis to evaluate the entity’s ability to continue as a going concern for one year after the financial statements issuance date. Management’s analysis includes forecasting future revenues, expenditures and cash flows, taking into consideration past performance as well as key initiatives recently undertaken. Our forecasts are dependent on our ability to maintain margins based on the Company's ability to close on new and expanded business, leverage existing working capital, and effectively manage expenses. New and expanded business includes the sale and shipment of newly developed hybrid-drive air-cooled chillers and the acquisition of additional maintenance contracts in February 2024. Our backlog at March 31, 2024 was $5,554,599. We may also be required to borrow funds under note subscription agreements with related parties (see Note 11.
