Re: Fission news(I know blasphemy )

The root post link says a great deal about cost. They go through an inventory of required materials and construction costs and argue that power from their plant should cost 3.x cents a kWh, versus 5.y for coal. They discuss the difference between 'should cost' and 'did cost' and argue that the diffe...

Re: Fission news(I know blasphemy )

Really interesting. If you believe this, nuclear is cheaper than coal, but for regulation. They claim that was the actual experience in the US before TMI. They also describe the passive safety features and claim the plant is 'walk away safe'. Also eye catching is the claim that a decent production f...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Check this out: https://wattsupwiththat.com/2017/01/14/noaa-jumps-the-shark-in-tampa-bay/ Willis seems diligent and level-headed, not prone to wilder flights of skepticism. Here we have a government science body causing real economic damage by predicting the utterly implausible, on the basis of prec...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Maui - I'm sorry for the sideways remark about food stamps. It was an attempt to make people busy advocating higher electricity prices to reflect on the consequences of their policies. On reflection let's not make this thread busy by getting into US politics (as well)! Your remark on sea walls highl...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Yes, I was taught about pumped storage when I was in school, in the 70's. There was a site Dinorwig (sp?) in Wales. Don't know if much has happened since. The sites are very specialised. You need a big lake you don't mind rapidly draining and filling at the top of a nice big mountain. I guess with f...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Yes, I agree on the distributed solar 2gw, that's what it said. It also said the range of power factors at 30-70%, from renewables to fossil plants. Yes on batteries too. When the per kWh costs of plant+fuel for non-renewables is more than plant+batteries for renewables, it has to be game-over. Plan...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Sounds like decent news. The obvious questions are what is the power factor of each generation type, I.e how many MWh will each actually deliver in a year - intermittency again. And questions on regulation - is there regulation artificially depressing the load factor on gas/ raising it on renewables...

Re: EM Drive

I guess we'll see. The videos of Paul March, the man who made the measurements, are long but interesting. It's on SSI.org, first of the day 2 videos. He is obviously convinced, maybe to be expected.

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Maui - dammit, I just lost 90 minutes worth of typing a response! I'm sorry but I don't have time to repeat it (might be a good thing)! So, short this time: rise above it. State your position and disengage if the discussion is impossible. Avoid insults and attacks. There is no global conspiracy, but...

Re: EM Drive

ScottL - believe it when we see it is right, but like you and anyone with any imagination, I'm hoping it's real. I was just responding narrowly to the suggestion that it's a photon rocket. The thrust levels are too high. In fact, that's why it's controversial, come to think of it. Also, if my calcul...

Re: EM Drive

The ratio of thrust to power in reported by Shawyer and others is way above a photon rocket. Eagleworks Labs was on the low side of the reports, and they reported 1.2 mN/kW. A perfect photon rocket is 3.33 micro-Newtons/kW.

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

On EV: 30 mpg I make about 5.3 cents per mile for fuel at $60/bbl. I think grid power is something like 2 cents a mile for EV. The numbers may well be off, but clearly there is point where there is insufficient cost advantage for EV to defray the capital cost of the battery. Yes, the dynamics of oil...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

I'm an optimist, and I agree with you that many of these problems will be solved. The policy questions circulate around what governments should do. I'm very relaxed about the government spending $100bn on relevant research which should accelerate carbon reduction. I'm really not relaxed about making...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Maui - thanks. Contact with one apparently sane human being makes trying to communicate worthwhile. No, I'm not going to make a case for everyone with the same label as me. You can make your own judgements. I'm forced to confess to an overly sweeping generalisation regarding the character of sceptic...

Re: Bill Gates is heading a $1 billion venture fund to combat climate change

Apologies: I'm sure my use of the term 'ludicrous' may have caused offence. I had in mind the throw away line about 'billions of deaths', which is obviously a measured, peer-reviewed, near as certain statement as you can get. And of course, none of the responses to me were remotely offensive. Furthe...
