fwiw, I think promising economic electricity is not a bad thing -- someone should be thinking about costs -- even if the promise is ridiculous until someone makes a device that actually works.

Any views about this? Certainly this is not the first effort to promise it will be "cheaper than coal." For example, Lerner of Lawrenceville Plasma Focus has predicted greatly cheaper electricity (1/10 current costs, if I recall).

What happened to American courage? -- Teddy Roosevelt pushed the Panama canal which was a radical project at the time -- one at which the French already failed. -- The Manhattan Project as an incredible leap of faith. American built whole cities and spent many billions (1n 1940 dollars) taking the c...

Power output for magnetic confinement devices scales as B^4R^3 pretty universally. Presuming losses scale slower than R^3, you can get better fusion gain by going bigger. The problem they've run into building bigger tokomaks is new unanticipated turbulence loss modes, related to the magnetic field ...

Civilization and prosperity may be a function of energy per capita -- aka "White's law." That doesn't work. Except for the weasel word "may be". Yes, it "may be", but it's not. My point was much more modest than perhaps it appeared. Simply: fossil fuels are in decline. This threatens industrial civ...

There are many dark horse fusion projects that have had delays that seem to have conspired to push their "effective net" dates into 2014 Civilization and prosperity may be a function of energy per capita -- aka "White's law." Fusion -- no matter how cheap the electricity it creates -- may not overc...

This is nice but not very useful. What makes the Polywell remarkable (if claims are true) is how much it scales up with increased magnetic field strengths. Keep in mind that a few billion neutrons per second only represents a fusion output of a few milliwatts. Very interestin', thanks! Forgive me i...

From the article: The Mark III Fusor produced startling high records in quick succession. By the start of 196.5 the team was routinely measuring 15.5 G-neutrons/sec. at 150 Kv and 70 mA. Does anyone know how Philo T's successors numbers compare? -- Hirsch-Meeks -- Bussard's Polywell -- Current Polyw...

This is a link to a chapter from the book "Lost Science" (by G. Vassilatos) about Farnsworth´s life and the historical development of the fusor: http://www.hbci.com/~wenonah/history/fusor.htm Another link to fusor history: http://www.farnovision.com/chronicles/fusion/vassilatos.html Great history o...

Add 5 years: -- Nebel gone from EMC2, Bussard dead -- The claims made for Focus Fusion were at a minimum overly optimistic (never mind the practical problems to create a reliable many-times-a-minute pulse device for repeated and practical fusion) -- TriAlpha's actual progress is as secretive (and p...

People want news, then they speculate and make guesses I disagree. The story here is not the "rabble making guesses." It's the fusion experimenters making promises they discover they can't keep. I'm not suggesting any wrong doing -- they probably can't do what they do without being optimists. But t...

Hydrogen. Given how easily it bonds with things, it can be readily stored as "something else". Like "Water". water + electricity = o2 and h2 (no doubt there is a more formal way to express that) Fuel cells reverse that equation: o2+h2 = water and electricity So you can' t use water as a fuel to mak...

Not to mention that hydrogen gas does not exist as a energy source for practical purposes. It never seems to be mentioned by hydrogen fuel fans Yep. No hydrogen mines anywhere. And hydogen is very challenging to store. The atoms slip through just about any containment. Your comment reflects the big...

The troubles with hydrogen cars are that a) they have to tote around hydrogen in heavy tanks and b) the hydrogen comes from methane so they're not really any better than a very heavy, overly complex methane vehicle plus a lot of wasted infrastructure. Just not in the "good idea" category. Fuel cell...
