Ok here’s another thing I was thinking about (remember in the wizard of oz when Dorothy looks out the window into the twister? That’s my mind… ) anyway I was looking at solar cars and it occurred to me that they make no use of the heat from the sun. This can add up to a huge amount so I thought why not put a heating coil the top and a condenser (radiator) on the bottom. Using the heat to vaporize a refrigerant this pressure could be fed through a pump and used to turn the wheels. Then when it reaches the cooling coil under the car it condenses adding a pressure drop. The whole cycle is then repeated over again. Would this work? I’m not sure.

Heat? Sun? Here in Britain? The sooner we discover a rain powered car then we'll be onto a winner

Mr Whippy, you appear to have to much time on your hands, you should go and work for Ken Livingston as one of his Green advisors

alternatively you could ask your boss for something to do

I did ask but I've done it all, bl$$dy annoying

I hate this, time slooooooowwwwwsssss ddddooowwwnnn zzzzzzzzz

Just waiting on e-mail reply’s from folk, a bit dull to say the least.

I was going to create a new planning template for the department but primavera has stopped working so I'm scuppered, stupid computers, never work properly.

heat from the sun? Why not look closer to home like utilitising the heat in the earth's core.

A car running on magma is the future.

On a smaller scale, why can't watches run off body heat?

ah ha, so how does it work?

i've got a solar powered watch... the problem is i cant tell the time after dark, the watch stops

what about clockwork cars? you have clock work radios don't you?

as to heat powered cars, even a fridge requires a pump to work, it is to do with the cooling and heating effects of compression and expansion. we dont get enough heat to generate the power required for the pump to work, and what happens when you go through a tunnel

Have you seen the Atmos clocks, they run on temperature differences - a 1degree change will wind it for 2 days.

Fascinating pieces of engineering.

Funnily enough I have seen it in Helsinki duty free; a bit expensive though.

I wonder if you can scale it up to wind up a car overnight?

you need to droill a deep hole in your garden andthe intense pressure foreces the magma out that you catch in a bucket, tip it into your car and used the heat from it.
