Ultra-low-grade heat is constantly dumped into the environment because its energy isn't able to be harnessed productively or economically. Current lower-heat engines are limited to using high volumes of relatively high-temp heat, but work poorly with input heat <250°F and are ineffective <200°F.
PwrCor uniquely generates "green" power from an abundant and typically wasted energy resource, ultra-low-grade heat. Its proven tech converts ultra-low and low-grade heat (140-300°F) into power, and can generate 3-5x more power than current lower-heat engines by harnessing far greater amounts of energy from a given heat resource. PwrCor is not dependent on the sun or wind and converts this heat energy to clean green power 24x7 - while reducing production of polluting legacy power.
