Document Summary
Article 1: 7 radical energy solutions: solar gasoline, sun creates more energy in an hour than civilization uses in a year. Air conditioners burn through electricity: 1/3 of home usage. Magnetocaloric effect: magnetic materials heat up to some extent when exposed to a magnetic field and cool down when the field is removed motors are more efficient than compressors. Heat is stored as vibrations, when metal can not move they heat up more. In magnetic coolers: motor spins the wheel which does most of the work, Uses only water to transfer heat: environmentally friendly. Texas: unusual cooling technologies: cooler that does away with refrigerants: relies on thermoelectric materials that are cold on one side and hot on the other, consumes less fuel and reduces emissions, quantum photovoltaics. If hot electrons are grabbed before cooled, maximum efficiency could. Quantum dots boost theoretical maximum above 60% (up from 31)
