Re-useable energy? I don't think this is the case. Precisely, its called energy transfer.

Heat energy transferred to Electrical energy, pretty much that.

yup. nothing reusable about it.
 
well, put it this way you have a hot cup of coffee containing caffaine (energy for you), and heat..... its re-using the heat to generate more electricity to charge up your phone right?

no. that would be an efficient use of energy with little to waste. exactly same concept as electric or hybrid car when braking and it recharges your battery.

reusable energy would be using what we consume and our goal is to maximize the efficiency rate so that the cycle can continue longer.

reusable water - we drink. we pee. we filter. repeat cycle. however... for every cycle we do this, some water is lost. electricity is needed to do this process and we can do that via solar power... thus making this entire process very green-friendly. that is what astronauts are doing at ISS.

in engineering world... nothing is ever more than 50% efficiency rate or even close to it... how sad.
