People power is perhaps one of the world's greatest untapped sources of renewable energy. Smart devices that harness kinetic energy from everyday human activities help the environment in more ways ...

Humanity is constantly looking at innovative technologies to help reduce our dependence on fossil fuels. Yet it’s not always the big discoveries that make the difference. Small inventions that reduce ...

A long time ago a formula was devised for calculating kinetic energy, the energy needed to move a body from one place to another. This energy (E) was dependent on both the mass (M) of the body and the ...

In my previous post on the Black Arrow from The Hobbit, I looked at the speed of some real arrows shot in my backyard. Oh, in case you didn't read that post, the arrow shot in the movie version of ...

JONNY NELSON: Energy. There are lots of different types and lots of different ways of storing it. Chemical energy in a sparkler, elastic potential energy that fires a toy into the air, and many, many ...
