Comments on: GE, Idaho Labs turn waste heat into electricity

Here's one way to make industry more efficient: A small DOE research project seeks to convert megawatts of wasted energy into usable heat and electricity.

This is HUGE!

I heard talk about this in the 70s. I think most power plants already have secondary generation.

I've always wondered about things like this, like when you're driving through an industrial area and you see flames coming out of smoke stacks, I can't help but think that energy could very easily harvested.

Re: "There are already waste-heat recovery systems operating in large industrial facilities that produce steam from smokestacks to turn an electricity turbine...."

Wow! reading about these technologies again (since the early 70's college classes in engineering thermodynamics....) certainly give one the feeling of getting old.

Funny how it only takes a couple mil from the Feds to make a 30 year-old technology seem brand new...
