Check out this wild high speed (1000 frames per second) footage shot with a miniature temperature resistant camera of the inside of an engine. You can clearly see the valves open, the spark plug fires, and the gas/air mixture detonates, pushing down the piston. This is going on inside your engine, hundreds of times per second.

Build your own cheap wind turbine

Free electricity is one of my biggest pet projects. If I can glean some free power from solar cells, a crank generator, something mounted on a bike frame, or a windmill, then I'm gonna do it!

If nothing else, to try and recharge my non-rechargable batteries which often don't take too well to that kind of thing (cheap batteries respond better than alkalines, ironically). But I do it anyway, to try and save a buck as well as be prepared for when World War Three wipes out the power grid.

Anyhow, this dude in Arizona has a complete website dedicated to building a windmill generator (turbine), and how to do the whole thing on the cheap, with pretty good results.

Six Stroke Engine Could Save Gas

This guy has invented a whole new kind of engine. You already know about 2-stroke and 4-stroke, but how about a 6-stroke engine, that harnesses normally-wasted heat energy by creating steam inside the combustion chamber, and using it to boost the engine’s power output and also to control its temperature.
