Lastly, is the IPCC the sole source of wisdom on the subject from the warming side? Or do other scientists agree with them? I mean, "consensus" aside, is it only the IPCC that's saying that warming is happening? Or are there not, in fact, many universities and other organizations, and scientists al...

Actually if you read my proposals at lorrey.biz, you'd see that SHARP materials (hafnium diboride and zirconium diboride) as are used as steering vanes on MIRVs are more than adequate TPS for hypersonic vehicles. They allow mach 7 at sea level, mach 11 at 100k feet altitude, and there is no radio in...

That's all interesting, but who pays out on the law suits? If you had just left the track of the hurricane alone, it would have missed my house, but because you messed with the track, I need a million dollars to repair my house, and $100 million in punitive damages. We'll make this a class action l...

Propulsion: Easier achievement?
It appears to me that building a stable operating power generating system for planetary use is a far more technically complex project than building a polywell that can be used for space propulsion purposes, or even launch vehicles. There would not be nearly as much a need for fine tuning a cooling s...

Re: To those concerned Obama was anti-nuclear (IntLibber)
In this thread (and the one that preceeded it) there were some claiming Obama was anti-nuclear. Thought you might be interested in what Obama's pick for energy chief says: Q. Should fission-based nuclear power plants be made a bigger part of the energy-producing portfolio? Absolutely. Right now abo...

Even efficient wireless power transfer (we can manage maybe 30% efficiency now over decent distance using microwaves and very big dishes) is not the same as free power. Best wishes, Tom quite so. However, JP Morgan was Tesla's backer at the time. When he heard Tesla wanted free broadcast power to b...

Re: Global Warming Concensus Broken
IMHO anyone that claims Global Warming is "greatest hoax ever perpetrated on the American people" should not be accepted as a trusted source of dispassionate information. This year he's fished 237 more "scientists" out that are willing to call themselves skeptics. But this list builds off of last y...

One thing that climateaudit.org has successfully argued about is that the 'hockey stick' chart is flawed for several reasons. Firstly, the software Michael Mann uses to generate it for the IPCC report is inherently flawed, you can stick pink noise into his software and get a hockey stick pattern (pr...

Re: News thread political tangent
ANY energy investment has to have a certain ROI given a certain prime rate. The higher the prime rate, the shorter the ROI period needs to be. Typically 2 years is an acceptable avg. Solar tends toward an ROI of about 10-12 years, which is very diseconomic. I suspect you are using figures from sili...

It would melt from the electrons hitting the grid long before the well reached the necessary conditions for significant p-b11 fusion. Even 1% is way too high, and iirc they usually operate around 5% loss. To begin with, hydrogen-boron fusion requires ion energies or temperatures almost ten times hi...

Some more about breeders and reprocessing... Though it makes sense to extract all the energy we can from the actinides by the means of breeeders, it is not the definite answer to the waste problem . At the end of the day, you get: -plenty of energy (thousands of years) :) -plenty of waste, fission ...

Awesome work by Musk and his team. Very exciting indeed, even though not revolutionary, they did an awesome job! Lets hope the best for them in the future, but I think that now things are only going to "go up" ;) They built a BDB*. A low cost high reliability conventional booster which should rival...
