Gates looking for energy solutions

Postby flying_eagle » Sat Feb 13, 2010 2:29 am

Bill Gates gets it about AGW, no carbon, and new cheap energy technology being needed.
Since he wants to spend money, anybody told him about Polywell? :D

We will need other energy sources in 50 or 100 years.

CO2 is not the reason:



The earth is homeostatic.

Re: Polywell. There is nothing to invest in at the moment. Unless some one wanted to head out on their own.

It is a good thing Bill is so smart. Otherwise you would need a really big computer to tell exactly what forms of energy will be required at any given place or time ten or 50 years hence.

I'll bet he can't even tell me what will be needed next week.

Well, although a lot of us are AGW skeptics, there are useful things here:

1. Realistically looking at building reactors that burn nuclear waste - something that's been talked about here. While nuclear waste doesn't terrify me, I don't particularly like it. I tend to think that no matter how well it's stored underground, it may eventually contaminate groundwater. It should be reused to make more power.
2. Better batteries. I think most of us want these. Think of all the uses, including in space travel. Also, fully electric cars, which can be powered from a nuclear power grid when oil does run out (the 50 to 100 year range). Current electric cars suck. Performance can actually be ok, but range and recharge time are poor (useless for my purposes - at least half of the time when I drive, I need to go hundreds of miles). Better batteries can fix that.

If he wants to invest in the right things for poor AGW-related reasons, I'm still happy to leverage that.

If he wants to put some of his foundation money into carbon sequestration research, well, it's his money... who knows, we might learn something interesting. Encourage him to put most of it into advanced fission and fusion research, and batteries.

Better batteries would be very nice, but the other side of the same coin is better electric motors. A break through in our understanding of physics could lead to motors which draw power from the vacuum giving coefficients of performance, COP of greater than 3. Use of this technology would extend the range of all electric vehicles by, well, 3 times for example.

Wait - don't scream at me yet. Do I really think the excess power comes from the vacuum? No, not as real power, but virtually? If it happens, it needs an explanation. Wait, don't scream yet. Do I really think that electric motors can develop efficiencies of 300%, No, but there is a strong indication that magnetic motors can do so. Just don't confuse the two, they are not the same thing.

Here is a patented method to switch the field of permanent magnets off. That is all that is needed to make magnetic motors work. I have found 4 different magnetic motor designs using this method, Steorm is one of them. To see the Steorm method work, watch the video here. Other designs apply the switching currents differently but fundamentally to the same effect.

In a nut shell, magnetic motors differ from electric motors in the way that they overcome back EMF. Electric motors use the application of electrical power to overcome back EMF while magnetic motors switch off the back EMF. Because the power needed to switch off the back EMF is much less than the power needed to overcome it, magnetic motors can operate with a COP greater than one based on the input electrical power which is just the switching power.

General Motors just recently announced that they will invest $Billions in their own new electric motor manufacturing plant. I view that as a strong vote for the above and for other state of the art technology. Existing electric motor manufacturers are not up to state of the art. If they were, then there would be no profit margin for GM to hope to gain by building their own plant.

OK - now scream, or better, debate the above points.

Ah no back EMF? Are you serious? But OK. Suppose it is true? It gains you nothing except a motor that works at lower voltage for the same power out. But the current goes up in proportion as the voltage goes down. Because you can't beat ohm's law. Or energy conservation. And entropy increase.

And if all these fabulous motors work so well why not hook one to a generator give it a start and make a fortune selling electricity to the electric company?

Why isn't the Navy doing this for their big superconductor motors?

I view the building and operating of nuclear power plants a vote of confidence in the psychic powers of Martians.
