HELP! How can I recycle "waste heat" from home appliances using home-based methods?

Question

I'm planning to make this as my investigatory project...recycling waste heat from home appliances into a more useful form of energy...what are possible uses of this waste heat? HOW CAN I RECYCLE IT????? heeelp! (I'm in grade 10.)

Answer 1

you cant, if anyone can name any domestic home appliance that generates enough heat for that to be transferred into a useful form of energy without the cost outweighing the benefit, I would be really surprised and definitely steal the idea.However, you should re-route the house plumbing and make a miniature hydro electric plant from the bath tub... that would be pretty sweet
