Nanotechnology never ceases to amaze me. Considering how complex we humans like to make things, not to mention how big we like to make things (SUVs anyone?), going ultra-small holds so many advantages. We talk about range-extenders when we speak of electric cars all the time, but the idea of carrying around an internal combustion (IC) engine all the time for the few times we would actually need to use it seems to make little sense in the long run. The problem is that with current battery technol
We don't usually cover things like rocket engines, as they cannot really be classified as being "green" in any sense of the word. This one is really no different, but it is 40 percent better than the engines currently in use, so I decided to go ahead and share it with all of you. I can't give too much commentary on how this works, but the article mentions that the engine can use solar power in space, and operators on the ground can control the exhaust thrust, sort of like how one might "shift ge
Researchers at the Macromodules and Interfaces Institute at Virginia Tech and Georgia Tech's School of Chemical and Biomolecular Engineering are working on a Department of Energy-funded project to develop more effective membrane materials for fuel cells.
