Bless! Are you an Art Student?

Must be. Can't even spell supersede...

I'm hoping for little, hand wound perpetual motion machines that just need
winding up every day to overcome losses will produce indefinite amounts of
electricity to replace batteries. You know, like when you stroke a dry cat on
a nylon carpet. I expect it is the insulation that is the biggest technical
problem.


Actually what I want is an an Atomic Aga. With back boiler. Running off
the decay heat of high level nuclear waste. When not employed cooking,
the heat is diverted to a back boiler for central heating and DHW, or to
a Stirling engine to generate electricity....

After 60 years you give the no longer hot waste back to Sellafield, and
receive another free brick of hot nuclides...
