new energy source

Take an old 12 V DC motor and propeller, and get many times that for the same size device.

A bit bigger and you have 2.75 MW, with a Vesta V100:

How's my math.

No free lunch. How much extra aerodynamic drag does the device add? It has to exceed the output of the device. If you want to increase the range of your electric car, you do what Toyota and Honda have done, which is to lower the Cd of the vehicle, not raise it.

But it's the kind of hare-brained scheme that keeps leftists happy. They'll probably claim it reduces global warming >:-} ...Jim Thompson

Just one more example of trying to invent a perpetual motion :-)

The only case I can think of in which a wind turbine might be useful in a vehicle is when there is a strong natural wind from the sides or back as in the Cousteau ship Alcyone

I just use one of these:

or one of these:

I'm quite sure I'm doing more to "save the planet" that using the above device, too.

I just thought of an expansion on my "prisoners must all ride generator bikes" idea.

You also place those bikes on a big belted tower ride machine that they put part of their juice into climbing up, as they are pumping into the grid, and when the crest the peak, their gained kinetic energy can be added to their return to the bottom.

Not quite perpetual motion, but at least we can make then earn forcing us to endure their sweating, stinking hulks of olfactory insulting emissions.

There is another promising energy technology called "Potato Power" for lighting LEDs where electricity is scarce.

For the past few years, researcher Rabinowitch and colleagues have been pushing the idea of "potato power" to deliver energy to people cut off from electricity grids. Hook up a spud to a couple of cheap metal plates, wires and LED bulbs, they argue, and it could provide lighting to remote towns and villages around the world. They've also discovered a simple but ingenious trick to make potatoes particularly good at producing energy. "A single potato can power enough LED lamps for a room for 40 days," claims Rabinowitch, who is based at the Hebrew University of Jerusalem

smells like a straw man to me.

Good luck with all those microamps of power.

so far it sounds entirely without merit

that last bit: not enough words.

cheaper, and ore energy efficient to make them stare at a wall.

They obviously hadn't heard of truck testing wind turbines...

Yet another project that I'm glad my taxes aren't subsidising.

Their cost analyses suggested that a single boiled potato battery with zinc and copper electrodes generates portable energy at an estimated $9 per kilowatt hour..

I do seem to recall that boiling a potato takes a huge amount of energy.... For that energy (whats it, 20 minutes in boiling water) where is the math?

It's been done. Google "cockchafer prison". (Not the insect, the treadmill, so named from the noise, which was apparently similar to the insect's.)

No, because then you have to pay the salary of the "honorable" asswipe employed to "make them". Not even close to being as efficient. Then you have another fat overfed slob adding methane to it all.

I say any time forced response is required, the mechanism should be a device which instantly lances off your nuts, if they are still there.

In some cases, a nice sharp spike insertion into each nut precedes their removal.

In every case, a nice "don't drink and drive" educational video gets created to use as a deterrent for other inmates thinking of disobeying the current set of rules.

Humane treatment is for humans. Prisons should be made such that they get populated with a "like class" of criminal. Once you end up in certain prisons, you no longer have any rights.

We need to cull the population. At least one more time.

Then, we need to control future growth of it, and "us".

It is the only thing we are NOT civil about yet.

Civil societies do not let criminal enterprises fester like puss sores, and expect no damage to said society.

Until we return to true punishment we're going to have an increasing problem with crime... particularly given our legalized "illegal's".

A good start would be to incarcerate all leftists before they take away all our Constitutional freedoms. ...Jim Thompson

Or incinerate.
