Do you remember the stock ticker symbol so we can watch out and avoid that company? Which company, the "investment newsletter" with the "hot tips", or the company they were trying to pump-and-dump? I never figured out what company they were trying to pitch, because it became obv...

Here is a source: http://en.wikipedia.org/wiki/Energy_density Work it out. I've found a different source. The MIT "Future of Nuclear Power" paper , has this to say: "Typical LWR spent fuel today reaches a burnup of 50,000 MWD/MT" (Appendix 1, page 105). Based upon that source, I...

Cool. I'll have to find a copy.

Bill Gates (in his TED address earlier this year), AND there website (checked yesterday) are both lieing through their teeth. I would not call those people liars but communicators. The scenario which I imagine is the following. . . But they kept the name in memory of the visionary and for the consi...

So, if I didn't screw up some math, I get that 1GWy = 8.76581277 * 10^18 kWh. One of us is WAY off! I get 24*365.25 = 8.7E3 hours per year and @ E6 k/G this gives ~9E9, not ~9E18 kWhr per ton. Oh, and that results in 11 billion dollars. ??? Ok, I'm not sure what I did wrong. I need to learn not to ...

You have to read to the bottom to get the punchline.


I should really watch Wall Street sometime - maybe it's on Netflix Instant.

I guess every industry is a target for investment scammers

As you may or may not know, I've been doing a LOT of homework on nuclear fission recently (I'm still very concerned about nuclear waste management and the potential to extract many times more energy from the 'waste' if possible - especially if Polywell doesn't pan out). Actually, even if Polywell do...

the 'travelling wave' is constantly, slowly (takes 60 or 80 years for the wave to travel top to bottom through the fuel) Forget about the travelling wave. I once was excited by this concept due to Teller. According to their latest publications, TerraPower have practically abandoned most of it. What...

Here is a source: http://en.wikipedia.org/wiki/Energy_density Work it out. Well, assuming Wikipedia is correct (which is never a sure thing), and assuming the values in WP are thermal, and assuming a .4 conversion from thermal to electric (that is, 40% efficient), then you're right - although the f...

A ton of uranium if fully utilized will produce about a gigawatt year of power. Are you sure about that? That sounds WAY too low to me. Here's why - there are 1GW *once-through* reactors in operation right now, and they run for what, 6 or 10 years between refueling? At 90% Capacity Factor, that mea...

These numbers should be grist for your calculator to give you what you are after. Yes, thank you. As near as I can tell, most of the figures I've seen about how long we can power the country on our 'waste' is probably not including the depleted uranium left-over from enrichment. I've seen some peop...

Oh good, speculation about where the money went. I love these flights of fancy! Here is mine. I'd like to say in my defense, that I was neither speculating, nor requesting speculations.

I guess adding this question to this thread is about as good a place to put it as any: I've seen a lot written about how fuel 'waste' can be reprocessed and burned, or, in the case of some reactor designs like the Travelling Wave Reactor that Bill Gates is backing, basically just burned without repr...

This is grossly wrong. As often proponents and opponents oversimplify allowing endless polemics to take place and confusion to spread in the public. It takes over 250,000 years for the radioactivity of used fuel to approach the level of uranium ore. If you went that far back in time, Homo Sapiens w...

I believe that they had to move because of space and power requirements. But I can offer no direct evidence to the forum. I guess as they scale up to larger test reactors, they need more input power to startup and maintain the reaction? Would these early prototypes, I assume, be designed in such a ...
