BBC NEWS on distributed micropower
: Nice review of various small-scale technologies. Interesting figure: "ground source heat pumps extract stored solar energy from the ground to run a home's central heating, and can cost as little as an oil-fired boiler to install. Widely used in the rural US, they produce three or four units of heat for every unit of electricity they use, and can be reversed to provide cooling." I wonder if new materials for the underground piping can make the energy transfer more efficient, reducing the installation costs of these heat pumps. 9:57:51 AM
