It is true that superheating water and ejecting it will give us the lowest ISP (in respect to superheating H2 as example), but it has a number of inherently interesting advantages: ... Anhydrous ammonia is an interesting comparison. A bit harder to store than water, but respectable density can stil...

Sounds like a return of Pons Fleischmann cold fusion.

To my eye it all reads like someone takes startrek too seriously.

Maybe Al2+6H20 => 2Al(OH)3+3H2 in a fuel cell that can deliver electricity, with the H2 sent to a second energy conversion stage?

By my recollection, the potential well was vital to the favorable energy distribution, ion vs electron, for aneutronic fuels. I also recall speculation that a well could be created without electron injection by differential leakage through the cusps. Of course then you need some other means of heati...

Even then, we need an arrangement where we can be confident it isn't photon recirculation in the feed line.

Of course if you import too much gold, the price of gold crashes. As has been seen when Spain imported gold plundered from the Americas, and the California gold rush.

Barrycade, as usual, speaks nonsense.

How much does it erode the impacted surface? And I presume ambient pressure has to be very low, of the O2 is likely to quickly react with the released carbon.

Blackbody radiation scales with the 4th power of temperature. So a 30% reduction in incoming solar energy gives less than a 9% drop in temperature. Not sure I follow your calculations. Thought it was heat loss by radiation was proportional to the 4th power of the temperature difference. Nope, black...

The F-302 is supposed to be ultra top secret.

Blackbody radiation scales with the 4th power of temperature. So a 30% reduction in incoming solar energy gives less than a 9% drop in temperature. On the other hand, if I've got my calculations right, a planet twice the distance from the star would have a roughly Earth like temperature.

"Climate change", second sentence in the introduction. Well, there goes their credibility. Fusion energy does not need a bogus climate crisis to justify it.

I didn't see Rossi's picture in the article, but a thermal generator with only 3 moving parts? Suggests thermoelectric generator with efficiencies ranging from 6% to 15%, that doesn't seem like a very good deal to me. I've read of Stirling-electric generators with a grand total of 2 moving parts, n...

Build a wall, steal a wall, who would have thunk it https://www.facebook.com/thedailyshow/videos/1164893220345695/?t=2 :lol: :lol: And...that's an argument for not building a wall? Or one for building a wall along with more border guards/troops to reinforce it and help keep it secure? If a bank get...
