producing electricity for 1/3 the cost (T&C's apply)

(1/8) > >>

Simon:
Ok before we start this academic discussion a couple of points: firstly this will only be valid in the winter when you need to heat your house anyhow, secondly it does not consider materials costs.

if one was to run a bank of thermo electric generator cells on a radiator connected to the house heating system one would get electricity. Gas costs 1/3 what electricity does and any wasted heat is being used to heat the house anyway - simple ?

IanB:
Wow, gas really does cost 1/3 of what electricity costs. Forget the thermo electric generator cells (that's a bit impractical), but it certainly seems like it might be economical to install a gas powered generator for your electricity and use the waste heat for hot water and home heating. What an earth is going on with energy prices in England? (I must check what's going on in California after I finish posting this.)

Mechatrommer:
since we dont have winter... can you provide link/picture to what is "thermo electric generator"?
actually my question meant is... for the \$1 gas, can you produce \$1 electricity during the winter?

That's the baseline question.
Using the best gas powered generator available, who much \$ of electricity do you get for \$1 of gas?
Then once you have the baseline, work out if it's feasible from there.
