You would have to mount the generator vertically but you could have the dog chase the buttered bread on a turntable. But it would not be as efficient since the natural energy in the bread would not be harnessed and the parasitic friction in the turntable would further reduce efficiency :D


Now what you could do is get a new GF or a hairless Sphynx breed of cat.

I would suggest a new GF. They need to be rotated on a regular basis anyway. :lol:

The 12VDC from my Jeep. We've drawn as much as 50 amps off that system, with no noticeable affect on any of the other electrical systems. For bench testing inside the shop, we use a battery charger, which puts out a voltage that is within a few hundredths of a volt to that put out by my alternator. It's still a work in progress, but with gas prices already nearly $4.00 a gallon for the crap stuff here, I'd be happy with ANY mileage boost I may get. Eliminating my gasoline usage altogether is my ultimate goal, however.

Storage of a sufficient quantity in a safe but portable form is usually the biggest problem. Did you have a plan for that issue?

I'm not sure I mentioned it here, but i also have seen some promising designs for vehicles using compressed air.
http://www.youtube.com/watch?v=OJeMnZuOOJU

The design shown above uses carbon fiber airtanks that, even if they rupture, won't explode. You can use whatever method you wish to power the electric motor that compresses the air to begin with, store it in larger tanks at a 'refueling' station, and refill your tanks on about 3 minutes. Pretty slick idea. I don't know if anything will come of it.

My problems with Hydrogen are multiple, but hydrogen fuel cells seem to have some promise, so I'm certainly not discounting it.

I'd love to hear what they are, so I can address them in my designs. Feel free to PM them to me.

Yes- by not needing it AS a fuel. The nice thing, as it stands right now, is that once I've converted my Jeep, I can still use gasoline (not as efficiently, however) by just plugging in my fuel pump relay. The change in efficiency, if that word can even be applied to my Jeep, is because of a change to the timing required in order to use the hydrogen- it has a much faster detonation speed than gasoline, so it has to be ignited AFTER TDC, instead of before TDC (Top Dead Center).

IIRC the 'Carbon Fiber' air tanks are an aluminium cylinder wrapped in carbon fiber, as opposed to being solely made of CF.

Pretty cool idea too. :)

Having said that: This class is irritating because it isn't just environmental issues, some of these people really do scare me in the fact that rather than find ways to co exist with nature and all that, they would have humans (and animals) die out. To me, the point of an environmental class is to learn how to better be present in the environment, not discuss killing off anything other than plants, which, from my understanding of how things work, take away animals and the planet would die out quickly, in a very simplistic way of putting it.

First off, they're probably for reducing the amount of humans on the planet, but extinction isn't generally considered beneficial. Either that, or you're honestly going to class with some absolute morons.

The "solar bottle" technique was used in sailing ships for ages, although they generally used a glass prism set in the deck. It's a good technique that some entrepreneurs sell for thousands of dollars (with designs slightly more complex than a soda bottle).

Reduce energy use.

Frankly, I think farts are the next likely source of power. Think about how many sewage treatment plants there are in the world! Now imagine if each one of those was able to produce relatively energy-dense, compressible, storable energy that already works in existing internal combustion engines. Think about how many dairy farms there are in the USA. Imagine each one generating both milk and the energy to keep it cold.

Actually, many sewer treatment plants are completely self-powered by methane generators installed right there. When you add up the savings in electrical bills over time, versus the cost of the system and the fact that the FREE fuel is going to be there whether you want it or not, it makes excellent sense.

Exactly! More widespread adoption of this proven technology would allow for cheaper and more clean energy. Plus, burning it down at ground level prevents it from beoming a greenhouse gas. Win-win.

The problem with methane, is that many of the sources are simply too small to make use of, yet, added together, amount to much of the greenhouse gas effect- look at the issue raised at one time about cow farts- how would you make use of that methane? Most landfills that CAN capture the methane simply burn it off with a tiki-torch sort of arrangement, as they tend to be capped off landfills, where nothing is actually in use, and building a generator plant on it wouldn't work, because of the constant settling. We have one like this near where I live- makes for a pretty colored flame at night, but not much beyond that.

These are just locations where the methane production is concentrated- imagine all the locations where methane is being produced in small amounts from simple bio-degrading of grass, dead animals, etc, like swamps, or even your own compost pile. The amounts produced are too small to make use of, yet add together to make quite a bit of gas. This is similar to the ozone holes we've been dealing with at the poles of the planet. The arctic hole was a later phenomenon, and has since been closed up, and the Antarctic hole is healing, all do to small releases of chlorine bearing halons ( CFC's/HCFC's) from spray cans and refrigeration gases. An on-going source of the problem is pool chlorine, but they haven't reached a point where anyone's come up with a plan to deal with that yet.

Another issue with methane, which requires it to be available in large amounts in order to be useful, is that it's simply not that powerful when ignited. This means a generator running on methane needs quite a bit of it, in comparison to say, LP gas, to have the horsepower needed to operate the electrical half of the unit.

Right, methane biodigesting and hydrous pyrolysis are good ways to make use of waste, but people don't really grasp just how much energy people use on a daily basis. The sewers and landfills certainly can't provide it.

My dad once said that there is no ONE solution, just a combination of several solutions. At least for the next few decades till someone invents a miracle.

Take for example cars: Theres electric, LPG, CNG, methane, bio-diesel, E85, E100, hydrogen combustion, hydrogen fuel cells and so on. None of them are perfect, and none of them will solve any problems alone, but they can all cover certain needs, and together they can do a hell of a lot! The same goes for power plants, just with different energy sources...

I was going to answer but why should I bother? While I'm no fan of the green movement I don't insult the people in it. They have their view and are entitled to it.

Also, self-suffienciency tends to run green. You hadn't noticed this simple fact in your post? I mean I could quote where you named green energy but, again, why should I bother?

So no, I think I'll just ignore your posts henceforth. Have fun hating people that may have something to teach you and that you could otherwise teach something.

Forgive my quoting myself, from another thread, but this seems relevant to your question;

IMO, before you consider solar, or other generation, you should invest most of your money in conservation. Reducing your energy needs to an extreme. Maximum efficiency in insulation, glass, doors, heating/cooling, lighting, energy star appliances, etc.
If you can reduce your need for power in the first place, then solar, or other methods, become much more doable. Taking an average American home and throwing some solar panels on the roof to become "independent" is a pipe dream.

Solar sounds sexy, but conservation is by far the biggest factor towards independence

pretty sweet, I want one.

Pretty cheep to make. And any handy person could make. I think like $40-60, using junk parts.

$10 used battery (as many as you can afford)
