It is standard practice to put the funding agency in the acknowledgment section of scientific papers. That has been the case in every scientific paper I have ever written and read. Any paper that does not state the funding source should be rejected from journal. If it was falsely left off the paper should be retracted.

Looking at the energy flow diagrams from LLNL https://flowcharts.llnl.gov/energy.html#2011 they only have the state-by-state breakdown for 2008 https://flowcharts.llnl.gov/content/energy/energy_archive/energy_flow_2008/2008StateEnergy.pdf. The total electricity generation from renewable (solar,hydro,wind,geothermal) comes to 6.6+237.8+53.1+270.8 = 568.3 BTU. As a fraction of the electricity generation of 1907.9 BTU this comes to 29.8%. Seems a little closer than half-way there already. But since we are only talking about increasing solar and wind, they would need an extra 67.7 BTU to meet this target, so if they doubled wind, and tripled solar then they would reach this target, so your comment of "aren't half-way there yet", makes sense if you look at it this way.

Well I'm a physicist, and I usually don't believe any numerical solution unless I have an analytical solution to an approximation of the numerical problem which I can compare the numerical solution to. Analytical solutions provide extremely useful benchmarks for verifying and validating numerical solutions.

If you're not concerned about the environment & pollution here's an experiment you can try. Go into your garage, make sure all doors are closed, turn your car on... wait...

Let me know how it goes...

I did exactly as you said, I went into my garage, made sure all the doors are closed. Turned on my Tesla. I'm waiting, now what?

The point is to not allow the bubble to happen in the first place, not to be the first to predict the bubble crashing. If the bubble can be prevented, then panic selling won't happen. When the market bubbles, and then crashes, it doesn't go to an artificial low, it just drops the the point at which steady growth would have taken it. By predicting possible bubbles and preventing them, you should be able to get steadier growth.

But they don't want the bubble to happen, that's the point. By being able to predict that bubbles are happening, the markets can sell off sooner, rather than allowing the bubble to continue growing, and thus once the sell-off happens, it is not such a dramatic down-shift, since the prices were not allowed to rise to artificial highs.

Comment Re:NIF is about nuclear weaponry, not energy. (Score 1) 438

So you are saying that we should throw all our eggs in one basket because you think one idea is generations ahead of the other, and forget about other approaches. How amazingly short sighted of you. Why does it have to be one instead of the other ? Why not look to the future beyond magnetic confinement reactors? Or you are so sure that this will be the answer to all our problems that we should stop research into everything else?

Unfortunately, National Ignition Facility has nothing to do with energy production and everything to do with nuclear weaponry.

It does have a lot to do with energy production. It is the first step towards LIFE.

LIFE, an acronym for Laser Inertial Fusion-Fission Energy, is an advanced energy concept under development at Lawrence Livermore National Laboratory (LLNL). Based on physics and technology developed for the National Ignition Facility (NIF), LIFE has the potential to meet future worldwide energy needs in a safe, sustainable manner without carbon dioxide emissions.

Its funded by the DOD, not DOE. Its primarily for research and stockpile stewardship. NIF isn't intended to be a prototype fusion reactor for energy production.

LLNL is funded by NNSA which is part of DOE.

Yes it is primarily for research and stockpile stewardship, but it is also the first step towards LIFE , which is a prototype reactor.

Let's be clear here. The purpose of the NIF is not to achieve fusion for energy production purposes. They just sell it that way.

They are not trying to sell NIF as the fusion energy production. It is the first step on a long road in that direction.

They are selling LIFE as the fusion energy of the future, this will be built on techonology developed for NIF.
