It's important to note, however, that Columbia's non-electric Omni-Heat offerings aren't included in the recall -- and, for the record, that stuff does a stellar job of keeping one warm without any whiz-bang circuitry.
These use an electric current to heat and ablate a material, producing a charged gas that can then be accelerated in one direction in a magnetic field to push the cubesat in the other direction.
Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).
The total heat and electric needs of the world can be successfully met by skillfully utilizing the rubbish human society generates each year in their homes and industrial and commercial establishments.
FORBES: Initiative Would Shutter California Nuclear Plants For Decades While Feds Ponder Waste
Mr. O'CONNOR: The ICP technology involves drilling holes--vertical holes into the ground and inserting long electric heaters, which then gradually heat the rock over a long period of time, and over a long period of time--by that, I mean two or three or more years.
