you know, I know this is old, but some black paint would have helped on the hot end. from that glare on the camera it looks like a lot if the light is being reflected.

also, like every other generator video, just volts is meaningless. A neon sign might use 20,000 volts, but only a few watts. Your car's starter might only use 12 volts, but nearly a thousand watts.

@htomerif of course, we know that, but thanks for your comment. This was simply a "proof of concept". We saw the higher power ones in Phoenix; that's impressive!

[frogjohn001]

really cool. what did you use the flint for? Did you pre heat the engine with the normal heat source before you used the lens?

[PatGirvin]

@frogjohn001 yes, we did. It was a very cold day, and the sun was in and out. sharp eyes!

well if you could make it last 100,000 years i'd say you're good.

[PatGirvin]

@heathovc :)

@ethanstephenson fun idea, but of course, we can't violate the laws of physics either :)

@htomerif You're quite right that the voltage alone is meaningless, and I actually did measure the output in watts for my project.

Unfortunately, I didn't know much electronics, and I calculated power using V^2/R, where R was the coil resistance... obviously this doesn't work because R is supposed to be the load resistance and the impedance of the coils would vary anyways. To others: a better way is to measure current using the appropriate multimeter setting in series with a known load. P=I^2R

NEVER EVER LOOK AT THE FOCAL POINT - IT WILL BLIND YOU EASILY ! ! ! !

items that bright just look very clear while they are destroying your retina. Be careful with the Fresnel lens.

His generator windings are very primative, as well as the black paint..and the higher the sun the more effective solar power...stil ..all in all very cool..way to go..I wish I knew about this stuff when i was a kid...all i ever saw was that similar crank and an 19 century mini steam engine hooked up to it...that was cool as well...lol..

@wcemichael i think the idea here is to get clean and renewable source of energy, not that candle or oil or any flamable stuff...

Is that thing in the middle between two wheels 'generator'?

the things need some improvement.. If this video, at least show what the amperages are it would be nice..

[GeDu89]

great :)
