Save Almost All the Energy With Passive Heated Homes
December 30, 2008 | 3 Comments
In 1991 Wolfgang Feist (German Wikipedia Link) a physicist from Darmstadt Germany built the first passive heated home. Now the estimate is that 15,000 homes across Germany and Scandinavia have been built with the innovations Feist pioneered. What’s different in a passive homes is ultrathick insulation very sophisticated doors and windows in an airtight design. […]

Anything Hot Equals Power
November 25, 2008 | 3 Comments
Low temperature heat, now claimed down to 65 degrees C is being used to generate electricity. That would scald you but isn’t hot in terms of being past the boiling point of water or oven cooking temperatures. It’s well within range of lots of geothermal. It’s easily under the waste heat temperature in most all […]
