Both talks reveal massive theoretical problems that have been verified many many times in the lab. Buzzard just pretends that the problem does not exist and does not address it at all (aka the energy required to hold the plasma far from thermodynamic equilibrium). While in the DPF, we get some crazy claims about magnetic fields in the mega Tesla range.
DD fusion is more than 50 time harder to do than DT fusion, and about 68 times less power density. B-p fusion can't even get to breakeven without some new physics to keep the electrons cool and to prevent the ions from heating them up. And even then its still 100x harder than DT or even DD fusion. We can only get close with DT in existing systems...
So why not demonstrate some breakthrough with DD first... then move on to B-p fusion. Its a classic sign of crackpotism.
I think you are getting confused with the early 1900, or your infrastructure is worse than China.
Really what the hell are you talking about? Turbines spike? Emergency systems include massive dump resisters at the station I was at. Response time of the *automated* systems was under a second, while the many tons of generator damped out anything quicker than that and these still the steam vent valves (you can throttle the turbines faster than the boiler). A full shutdown startup cycle was 6 hours tops and we had five units, so we would not have to do the full cycle on all of them (one or two are at idle depending on maintainance schedules). And that was a slow full steam plant. Gas turbines can do it under an hour I believe (the bottoming cycle takes longer IIRC).
I just let some simulation software run for 2 months on a 250 core cluster. This uses many simplifications so that it wouldn't take years to run. Just because your PC is sitting idle all the time is not the same as all computers are idle. We are just about to spend another 150K EU on another cluster. We need faster cheaper machines... (that use less power... cooling and power connections are eating our budgets)
quantum teleportation needs a classic channel. So you have a speed limit of c. Also you get *zero* fanout and there are other *theoretical* problems let alone practical ones. Even the big proponents of quantum computing do not claim that quantum computers will be made obsolete by them. Event the few algorithms (we have almost none) we have need a substantial part done on a classic computer. You can't beat causality with a classic computer either... So i don't know what you are on about there. Unless we are talking about a QC from a science fiction novel.
However you need to understand quantum mechanics to build a transistor. So you still use quantum physics to build a classic computer.
I think you missed the economic meltdown memo. My friends retirement fund went from 100K to less than 7K. The way we expect >3% growth or more (more like 10%) you are guaranteed to have a meltdown once or more in your lifetime, so good luck with retirement. And mark my words, this meltdown hasn't finished yet.
Add to that that a lot of the long lead time stuff, has off line, and even warehoused spares. As for kill millions comment in GP? Please.. Power failures are a nuisance, and are not all that rare. Anyone that needs power has backup generators (even by lab does). Its going to be hard work to kill even a few people.
..."eating sweets every day" or "not eating sweets" which is very coarse categorising.
This is often done to get a significant test result. A Chi2 correlation test will give different results depending on the "bin" sizes.
So you start with fine grained bins and then start pooling until you get a significant test. If you still don't get a significant result, try other tests that can be used. This of course creates massive problems for the validly of any "significant" result.
Hold that thought, and that just the short list, make sure you read the claims.... The patent office has permitted everything to be patented. The problem is that when it come to the courts, its assume that the patent is valid and a default injunction passed without even considering whats in the patent...
Try reading the patent. The structure is the only thing in the dam patent that is not prior art. This is patenting standard lab techniques that most lab folk know and do on a regular basis. Check out some of the comments further up.
When i was working with a Grant from the NIH, I was expressly forbidden to get a patent on any of the work we did.
When a university or company say they want to be rewarded for the 20Million invested, that is often Public funds from the taxpayer... Who now must pay more for the next step of the work cus the methods to study it are now patented.
200kW space based power systems with a mass footprint and long life have not been even close to demonstrated. This is a long way from cheap, at this stage. Also there are other alternatives to VASIMR.... Some of which are flying right now.
I don't see any gravity in those numbers. Neither earths or the suns, both of witch is rather significant for that kind of acceleration. In fact its going to struggle to even over come the drag on the ISS at its current altitude. Now to get to Pluto you need to be traveling in a circular like path so the actual distance that needs to be traveled is far greater. And finally you need to stop when you get there...
There is also the weight of the nuclear power plant for the power + radiators to get rid of all that heat. Solar is not going to cut out past Jupiter...
This has been a pretty poor "covert battle" since the belligerents manage to sneak it into international headlines on an almost weekly basis without any combat engagements.
Because my quality of life is seriously impeded by the inability to use a cell phone while driving, *without* a hands free set. Oh the humanity.
Next thing you know they will impose speed limits, minimum mechanical requirements for cars and, God save us all from the freedom hating governments, require drivers are certified to drive by passing a standardized test.
Sometimes you "freedom" people come across as real dicks.
This was the AA argument against this law when i was in NZ last (3 years ago). It was that yes cell phones do distract drivers, but so do stereos, children, ex girl friends, that "God she hot I can get a second peek in the Review mirror" chick on the foot path and of course map books and hot pies. mmmm pies....
Drivers that can be easily distracted to the point of being a danger will be distracted by something. The rest of us are probably fine. And the few who think they are best drivers on the road are the worst of all.
My old uni did just that. The down time with 128 PCs was pretty high. Sure you could use it we less "cores" but... then its not a 128 core machine then is it.... The real killer was paying sometime just to get the broken down ones fixed.
We went with blades next. Up front costs was more. After 2 years it was cheaper over all than the cheapo version.
Unless you are going over the US border... In that case "inalienable right" hardly applies to US citizens let alone someone from another country. And no matter what you put in the US constitution... its not applicable to other Sovereign Nations unless they want it to be.

What do they need the warrant for?

And for some algrothims that need previous results have not got faster. Not everything can be speed up by a || computer.

Thats doubly true when its with money....

You can't patent, say,..

It's a tool made by our government.
In fact its a tool America copied off the British Government.

Some end of life deorbit systems use exactly this idea. Google tethers.

Like this?
Well it would be a 100-Petabit Internet backbone... if it was just 1 km long. ;)
Is it a lie if they don't know its a lie?
Seriously, salesman == liar has got to be one of the first things you learn after you first round of pocket money....

It will only help make a nuke if they provide a nuclear UPS.
