Well developed, mature technology to convert Solar to heat / electricity with continual efficiency improvement
This is the back-up technology that will make the alternative energy resources serious main stream competition.
Various waste heat to electrical energy solutions exist and produce kWh in real time.
Various methods exist today to transform municipal solid waste (MSW) to usable forms of energy.
Life sustaining biomass is a sometimes overlooked source of alternative energy and is largely untapped.
The race is on in this well established technology to increase efficiency and decrease operating speeds.
