Wow, this is interesting! So this replaces power plants? Like intead of running off of water you use this? Like a wind turbine without wind? Sweet! Or a magnet powered car! I think it could work in conjunction with elecricity. Like use electromagnets to make it more powerful. And so you can controll the speed.

If you're looking at this post and it was made before 2008, just ignore it.

I saw it, and they admitted that it can't really be called free energy because the power is coming from a power plant and therefor isn't free.
I believe, that if perpetual motion was to ever be created, it would most likely be done in space. Due to the zero gravity and no air resistance, it would be the perfect environment for something to keep moving.
Oh, BTW, the site's down.

I have one idea to get perpetual motion, but don't know if (or think that) it would would work. Have you ever seen those generators you put on your bike tire to have a batteryless headlight? You could greatly improve the efficiency of how those things work, and then connect it to a motor rather than a light. It may work better to have 2 generators connected to the same motor, I'm not sure, but it's a starting idea

The closest thing to free energy is hydro-electric, geo-thermal and (can't remember the name) another thermal power plant. The reason being once you get the plants you're not investing anymore money into having electricity generated. They're all powered by either a renewable power source or 100% self contained.
Also the elaberate the third power plant type I mentioned involves using the pressure and cold temperatures of the deep ocean to have something like amonia condence into a liquid and use it to move thermal energy. Like going backward with a refrigerator.

Yeah I'd agree with Spark, any energy-source Earth related that doesn't use fossil fuels is basically a free energy source.
Take ocean wave generators, which is a new thing I guess. Waves come from the Moon orbiting Earth, thus in a way you're harnassing the movement of the entire solar system to get power.
One thing to consider is that any sort of power generating device creates friction on the source, be it a river or wave. Granted it's a drop in the bucket, but they probably said that about CO2 levels 50 years ago.
I think ground source heat pumps are cool, expensive, but worth it. We waste so much energy in conventional ways it's often hard to think of alternatives.
Final note: there will never be an end to the Energy Companies of Doom! While it may seem odd that BP and Shell invest so much in alternative fuels, it's because they want to be ready for the day when oil runs out (or the Mideast plain blows up) and then they'll be ready to sell you their wave/geothermal/whatever power. Since you or I probably can't set up an infastructure to use waves to power New York, we're always going to need these billion-dollar behemoths to do it.

But you need tractors to plant, harvest, and transport them, and they burn fuel. And I think I read somewhere that for every gallon of ethanol made, theres like 10 or 20 gallons of waste water. I think ethanol and hydrogen are a bunch of crap, hydrogen needs a way to be separated from oxygen, and that takes electricity. I'm thinkin' cold (or regular) fusion's gonna be the best bet.timmeh87 wrote:making ethanol from plants is pretty "free". they keep growing back!
Ethanol from plants is a renewable fuel source not a free one. You have to grow it, collect it, filter it and then ferment it. Too much work to keep it even remotely free.timmeh87 wrote:making ethanol from plants is pretty "free". they keep growing back!
Well everything cost fresh water, so to claim that it cost fresh water is like saying food cost money. Also there have been plans for awhile that if we switched to a hydrogen based economy local fuel stations could use solar power to crack hydrogen and oxygen apart, it doesn't require too much energy to do just a lot when you need to fill a car. Cold fusion is a myth, and until the Brits can get that nuclear reactor outputing power rather then drawing it in we wont have it.vskid wrote:But you need tractors to plant, harvest, and transport them, and they burn fuel.

Really Ethanol is the bridge to hydrogen. And we're going to need hydrogen anyways if we do manage to make fusion reactors.
