- They are still made. The advantages are no noise (no motor), no
- electrical interference (no thumps on radio and hifi) and no moving
- parts to wear out. But note that the gas is simply the power, not the
- refrigerant. You can also buy electric versions which simply use a
- heating coil instead of a motor. But public ignorance is killing the
- market and they may soon disappear: I've met countless people who have
- have exclaimed with delight over mine and said that if only they'ld
- known such a thing was possible they would have bought one, but...

- I blame underfunding of science education in schools. The principles
- of refrigeration can be taught to primary school kids, and you can
- knock up demos with little more than kitchen equipment. Yet most people
- haven't a clue.

- Someone once said that a civilisation is doomed when most people
- haven't a clue how the technology they own and use every day works.
- The first stage of the decline is being ripped off by repairmen who
- overcharge for fixing it. The second stage is being swindled by
- repairmen who charge you and don't fix it. The third stage is giving
- up and buying a new one when the old one needs fixing. The fourth
- stage is making throw away products designed to be unfixable. And so
- on. And the root is simply poor education, monkeys in charge of a
- civilisation they don't understand.
