What about magnetic energy systems ("free energy")
There is a blog that describes using a superconductor device as a electrical generator. What about this?

Re:Biggest Shame: Emotion Trumps Science
Forty-three cents (Canadian) per kWh is what is on offer to pay rather than what was on offer to sell. And you'll see that it is a fixed duration contract so the power must be bought. You can't really compete with that even if you are cheaper solar.
This is why I'm writing the blog, to try to get my mind around the changes that abundant renewable energy brings. I think you are correct that price will be a factor, but some aspects of the way renewable energy works now would go against that. For net metering http://mdsolar.blogspot.com/2007/03/net-metering.h tml systems, the utility basically has to accept the power, if they don't then they are penalizing the customer and net metering laws don't allow that. At some point that also means that the utility will have to sell the power rather than just buying less from the commercial sources on the grid. I think that by then time of use rates will be pretty common and I'd expect they'll cut rates by a lot to keep from going broke. That is: charging less for retail than for wholesale whenever net metering systems are covering more than the utility's customers are using. Their non-net metering customers will get very low retail rates (during that period) but the utility will only have to pay that much as well so they'll cover costs with their wholesale transactions. Since they control what the net metering systems get paid, they'll be able to undercut any other price on the wholesale market.
Now, with an energy glut, commercial wind and solar will certainly be cutting prices and perhaps nuclear will follow, but as soon as this leads to deferred maintenance, (hopefully) the NRC will be all over them. The NTSB and FAA watch for the effects of price wars on aviation safety to some extent, as an example. So, nuclear power has a hard time cutting prices to compete.
The point is, renewable energy really is free to produce once the investment is made while non-renewable energy has fuel costs and thus operating costs. You have to pay highly trained people to keep them going. A wind farm in bankruptcy may lose a few turbines in a year but the recievers will insist it keep producing with what's left. A nuclear plant in bankruptcy will cut payroll and shut down. All of this is modulo power storage, which is another market for extra renewable energy, but once you have this, you'll have covered what used to be called base load. But base load is what nuclear plants are for. I think that most likely, the decommissioning of nuclear plants will happen before base load is fully replaced by energy storage though. -
Re:Biggest Shame: Emotion Trumps ScienceThat said, I feel that renewable energy kind of closes down options for nuclear power generation http://mdsolar.blogspot.com/2007/01/why-renewable

Your analysis is flawed in many ways, not least of which because you don't seem to understand that in the case of hydro, they are not limited to a choice between a) let water flow and generate power, or b) turn off the tap and hold it all back. They can let water flow by without power generation, and that is, in fact, the way large power grids deal with variable demand. Hydro power is the easiest to adjust to real-time demand variation so it's used as a "buffer".
This is beside the point though. Your entire argument is based upon the presumption that, in the future, growth of "free" renewable power generation will result in a huge surplus in generation capacity, thus requiring one portion of the generating infrastructure to be shut down. Now which gets shut down first? You approach it from a (flawed) technical analysis. In real life, the selection will be made mostly on price. The nuclear plants, at 4-6 cent per Kw-H, aren't going to be it. Cheap solar (and wind) is going to be competing with cheaper solar (and wind), because solar panels and windmills aren't free, nor is the labor to install, maintain, and operate them. As TFA says, we're looking at 43 freakin' cents per Kw-H for solar right now. It has a long way to go before it can knock nukes offline. -
Re:Biggest Shame: Emotion Trumps Science
Fission uses neutrons which do have a finite life time so I suppose that with a very big plant and some magnets you could extract a current when they decay. The gamma radiation might be converted to a current as well since Compton scattering (by definition) transfers momentum to electrons. I kind of suspect you'll get more of what you want with coal http://www.sri.com/news/releases/11-11-05.html.

Re:Ratio's
I'm OK with you up to the 4 kWp number but I think you need to say "month" or something in there to get to what I think is 1400 kWh since you convert this to price. There you'd be assuming 8 hour days rather than 12 hour days though.
The reason it is a little hard to fit this on the roofs of the houses that it would power is because they are going with lower efficiency panels (which should also be cheaper, I suspect a contract with Nanosolar). The key here is that they've got the land so spreading out a bit is fine. I also notice that they are unwilling to say what their cost is. I'd expect $0.10/kWh (Canadian) or maybe less. They are taking advantage of the high rate that is being payed but I'd guess they could do it for less and still make money, just not great big gleaming piles of money. In NC, small producers are getting (US$0.2 per kWh and liking it a lot http://www.ncgreenpower.org/about/producers.html.

Matching your utility with solar power (7 cents/kWh and up): http://mdsolar.blogspot.com/2007/01/slashdot-users -selling-solar.html -
Not really
The power absorbed ends up as heat. You could be either increasing or decreasing albedo when you install a solar panel. If you do it on a white roof, then less energy will be reflected to space, on a black roof, more energy will be reflected to space, but both what is absorbed in the panel and what is converted to electricity turn to heat.

Re:Is it possible to use only renewable sources?
There are more than sufficient resources to use renreable energy exclusively but we need to think differently about how power is managed. In my opinion, the base-load concept needs to be transformed into a fully demand-response-supply-management concept where stored renewable energy is held in reserve to handle time domain demand-supply imbalance.

Net metering
This program recognizes the higher value of peak power production and this pays a premium (in Canadian dollars) for power as it is delivered to the grid. There is also a premium for non-polluting energy here. In some places in the US (in 41 states) utlities are required to credit the extra power you produce yourself at retail rates. If there is no time-of-use metering, then there is no particular recognition of solar power's timely production profile. This way of doing things is called net metering http://mdsolar.blogspot.com/2007/03/net-metering.
h tml.
If your father lives in a net metering state, he might be interested in an in between solution of renting the equipment rather than renting out his roof. This can be done in a way that fixes the rates for up to 25 years, has maintenance included, and does not have the big upfront cost of purchasing a system. You can learn more about this by following the links at http://mdsolar.blogspot.com/2007/01/slashdot-users -selling-solar.html. -

Dr. Jacobson is alright. Just not as a witness.I don't doubt that Dr. Jacobson knows what he is talking about. However, he doesn't come anywhere close to meeting the requirements for testifying in court. Check out the second link which ultimately goes to the motion to exclude his testimony. The court needs to look at four criteria to determine if the expert's testimony is allowable as evidence:
- whether the expert's conclusions have been tested or are testable
- whether the expert's conclusions have been published and subjected to peer review
- the potential or known error rate
- whether the expert's conclusions have gained general acceptance in the relevant scientific community.
By his own admission Dr. Jacobson fails on every count.
We all know there are huge holes in analyzing the evidence. Ms. Lindor can not call an expert to dispute Dr. Jacobson's testimony because his methodology has not been published. it has not been subject to peer review. There has been no formal analysis of the reliability. And his methods have not gained enough acceptance for anyone else to be familiar with them. If Ms. Lindor can not call her own witness she is denied due process. The RIAA may as well just use voodoo science.
If Dr. Jacobson's methodology had been subject to peer review, there would be peer-reviewed articles analyzing the details brought up in the deposition such as IP spoofing, malware, the Kazaa protocol, and MediaSentry.
The motion to exclude brings up a couple other huge problems with Dr. Jacobson's testimony. It's not that Dr. Jacobson is a bad guy or that he is somehow incompetent. The problem is that Dr. Jacobson can not draw any 'expert' conclusions in the legal sense. NewYorkCountryLawyer always puts the word 'expert' in quotes when he mentions Dr. Jacobson. I think that's because Dr. Jacobson is not legally an expert.

I did a multiseat setup using Ubuntu for Software Freedom Day last year and it worked quite well. The only way I was able to achieve hardware-accelerated 3D on _every_ head was to only use NVIDIA video adapters with the proprietary driver. (yes, I'm aware of the irony!) Unfortunately, none of the free (libre) drivers supported accelerated 3D on multiple heads at that time but perhaps things have changed with the latest release of Xorg.
Setups like this are quite fascinating to me as they reveal how much more efficiently a computer of moderate specs is capable of being used--desktop users don't even notice that they are sharing a machine. Some aspects are a little complicated (like mapping different sound cards to the correct seats) but IMO there is a _lot_ of potential in this area due to ease of administration, energy savings, and a decrease in noise (less computers means less fans whirling). -

Re:Bussard's Polywell fusors?

Web apps are more susceptible to failure.
Web apps tend to be far more susceptible to failure than traditional desktop-based applications. This is a widely known fact, that many people have written about. Here are a few such articles talking about when web apps go bad:
7 More Reasons Why Web Apps Fail
What's The Worst Web Application You've Ever Seen?
Web 2.0: A serious case of diarRIA.
AOL's AIM Today Beta: When Good Web Apps Go Bad

Technorati listed a lot more articles beyond those. So it's safe to say that web apps just don't offer the quality and reliability we'd expect from even the lousiest of desktop apps. At least when a desktop app fails, you usually are able to try to recover your data on your own, from files stored on your own system. But that's not something you can do with web apps. You'll just have to hope and pray that whoever manages the web app that just failed is able to recover your information. -

(I watched that presentation and while it was compelling, I actually think the funding decision made is the correct one. There's a couple of things he really ought to show on a smaller scale before trying the $200 million project; I don't think he's anywhere near exhausted what he can learn with his smaller prototypes.) -

If you think the RIAA challenging the counter-claim is not news, fine. That doesn't mean the rest of us are not interested.

Really BIG fusion: http://mdsolar.blogspot.com/2007/01/slashdot-users -selling-solar.html -
Re:Why capture CO2?
I think you have a very good point but careful planning is hard. In a meeting I was at with Steny Hoyer's Distric Director http://events.stepitup2007.org/reports/472 the big news was the the task force in the house was feeling that meeting it's July 4 deadline would be pretty hard.
On the other hand, shifting to renewable energy is probably cheaper than trying to sequester CO2 from fossil fuels so what this buys us really is insurance against the chance that we've already passed a tipping point towards positive feedback or will do so before we can bring emissions under control. This kind of technology might be able to keep up with natural sources of carbon released owing to warming soon enough to stop that release and avoid a runaway.
We don't know if we are in that situation or not. Lackner's big thinking could be of huge importance.

Depends on what you mean by containment
Fusion reactors could produce some short lived waste, but they are not prone to melt down and so don't need the heavy containment that fission reactors require in most countries. Table top fusion is also advancing so I'm not so sure things have to be big to be useful. For Tokomaks this probably is a requirement but not neccessarily for other methods.

m l. It is 3 meters tall and captures about 18 kg of CO2 a year or about 4.5 kg of carbon. At this scale, it is probably not so good as a tree. These devices need to be much larger to compete with plants on the rate of carbon capture per unit area.

Re:Why bury the carbon?
Lackner is addressing a problem of scale. If we had such a large demand for carbon as an industrial material that we were entering price competition for use of carbon as a fuel, then your suggestion might work, but the scale of carbon use as fuel dwarves that of industrial use. And, it is not clear that asphalt, plastic, wood and other large scale uses of carbon will not lead to oxidation anyway. Stripping oxygen from CO2 has to paid for in energy which is why we get our carbon from easier sources and would continue to do so even with this technology.

Re:And for one very simple reason
I think the reason then that you have such animosity is that you are not persuaded that there is a crisis. When there is a crisis, control over people is what happens. When there is a real war, there is a draft for example. Half measures don't ensure success. Perhaps you should consider if you opinion concerning global warming has been influenced by people who actually control you http://mdsolar.blogspot.com/2007/01/your-opinion-
c ould-be-paid-for-by.html in a manner that is less honest than a plainly stated desire to require reductions in CO2 emissions.

Commercially viable?
It is important to remember that this is an added cost to the price of fuel. The cost, maybe $0.30/gal is not so large that it looks like a killer, but you can't make money from this without making this connection. To go beyond just compensating for emissions and beginning to reduce atmospheric CO2 concentrations requires further cash input. So, perhaps you require each pound of coal used to pay for 8 pounds of CO2 sequestered and that raises electric rates by 4 cents per kWh. Pretty soon you put coal generation out of business since renewables will fill in.
I think that what we should call this is potentially commercially feasable and reserve viability for things that increase economic activity.
