I am in favour of Manhattan like project too but I don't see the any western goverment having guts to do it...what China is doing is close though

Appreciate that but the stakes are very high if we get this wrong. I am rather in favour of an international Manhattan-style project to develop the next big sustainable energy technology, a project that is void of commercial interests and whose outcomes are free and open for everyone. I dream of course as there are too many powerful vested interests....

More concerning are the effects of wind turbines on weather and soil moisture. Google "wind turbine turbulence soil moisture" and you will find a slew of articles, both simulation and measurements, that the additional turbulance near the ground surface level causes moisture to evaporate and dew not to form on the ground. Add this to the location of the wind farms, at least in California, which reduce the flow of air from the cooler and moister sea to inland hot and dry areas, I am concerned about the potential for negative climatic effects. The bird kill problem (google "wind turbine bird kill"), if it were from any other "less green" energy source would be quickly addressed. Personally I'm hoping for liquid thorium fluoride reactors (lftr) development - these can be used to consume the waste we are keeping in so many cooling pools and are afraid to bury - they produce much less waste with much shorter half lives by avoiding creating the long lived actinide series elements. This is probably why our early ltfr reactor was killed in the cold war - it made no plutonium for weapons. LTFR reactors can not melt down - they are already liquid! They are hot enough to efficiently generate hydrogen without electrolysis and have good efficiency even without using water cooling (though better efficiency with a cool sink). They are operated at atmospheric pressure, with liquid salt cooling loops, so radioactive steam leaks are avoided. Thorium is present at about 10 ppm in most soil, and North America is one of the large reserves. Using these reactors to consume the stock of waste fuel rods rather than burying them would probably be less expensive than burying them and the waste that remains mostly decays within 60 years and is to a background level in 300 years rather than 10,000 years.

But sometimes you need direct subsidy to get certain technology going if the barrier to entry is very high

The direct subsidies to green energy firms is also a worry to me.

Corruption risk always exists...but much serious problem in public money R&D is waste, in my mind large portion of teh money awarded is typically wasted...typical application grants are checked carefully when you apply but after the fact nobody bothers to check what you have done with the money

I personally do not know who and what to believe anymore. There is just too much public money involved in green energy R&D. It's inviting corruption at an alarming proportion in science and engineering :-(

Economics of wind energy is already hard enough...wait until we have a plane crash due to wind turbine activity...clearly understanding risk is very important here...Kris
