HVC is dedicated to the development of machines and vehicles powered via stored thermal energy. Our innovative heat reservoir steam engine (HRSE) design promises a practical third way of storing power for mobile machines including, but not limited to: cars, buses, boats, and lawn equipment. As with the rechargeable electrochemical battery, power is ultimately derived from the grid, but HRSE charges much faster and never needs replacement.


HVC is an early stage Maryland C corporation. We are actively seeking capital in order to test the performance of our HRSE design. If you're interested in taking a financial interest in this ground breaking work, contact Jim Kodak at or you may call him directly at (443) 831-6838.
