The headlines for the above link is:

“Draw your own doodle about: If I Could Invent One Thing to Make the World a Better Place…”

I just came across this on Google and there are too many things in my head. But definitely something that is sustainable. Perhaps anything with an unlimited life and is environmentally friendly. One thing I am thinking is that there would be a special machine that transfers computer-generated heat into a heater to preserve extra heat when needed. This way, buildings can significantly reduce the use of electricity and gas on heaters during winter. I do know that Johns Hopkins University’s one library do not need a heater due to a large number of computers into a library. Unfortunately, when the library is closed and all the computers are shut down, heat may be lost. When the computers are on while the library is closed, then this is nothing but a waste of electricity. Class, what is your idea?
