Einstein Fridge

So he was also inventor, which, knowing what we know about what he knew, shouldn’t surprise anybody. An electrical engineer in the UK is bringing back a design patented by Einstein that uses no electricity. The design replaces freon with ammonia, butane and water and

takes advantage of low air pressure to reduce the boiling point of butane. In order to achieve a cooling effect, butane is heated into a gaseous state and then mixed with ammonia before being passed through a water-filled condenser. Here, the ammonia dissolves and the butane is released, before the cycle begins again.

Again, look at the date on the design. 19 friggin’ 30. What have we been doing?
