I explore the science behind a DIY X-ray generator project and the technology that makes X-ray imaging possible. This ...

Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces ...

Electric-power production is a conservative business; it makes electricity just as it did more than a century ago—by driving copper wires through magnetic fields. That is all that happens in the huge, ...

We were always amused that one of the biggest scientific discoveries of the recent past — graphene — was started with pencil lead and Scotch tape. Now, researchers at the University of Alabama in ...

So, I want to make a small hand-operated electric generator with my kids just to kind of show them how this kind of thing works. I understand the basics, but there are some things I want to do that I ...
