Amateur Scientists Seek Fusion Reaction
ElvaWSJ writes "A small subculture of amateur physicists and science-fiction fans — fewer than 100 worldwide — are building working nuclear-fusion reactors at home. The designs are based on the work of Philo T. Farnsworth, an inventor of television, from the 1960s. Some of these hobbyists hope similar reactors can one day power the planet, but so far they consume more energy than they create."
I don't think anyone building these expects to ever have a net power output from them -- that's not the point. The point is to be able to say you built a fusion reactor, or as others have said to generate isotopes for other experimenting, etc.
IMO, a more important area of amateur and admittedly fringe scientific research around fusion and fusion-like reactions is the several hundred teams that still continue to this day to investigate what the heck is going on with low temperature fusion. Tons of progress is being made in the field, and some reasonable theories are starting to form. There's a lot of unknowns, but helium is regularly produced, neutrons are regularly produced and more interesting from a theoretical standpoint, lots of atoms are changing from one element to another...
Its like the 1700's experimenting with chemistry. Lots of people doing lots of very cool and interesting experiments and getting lots of very interesting results, even if we (humanity, not me personally) still don't quite get it.
IMO, its an aspect of science we miss in the modern world. These days we just assume we understand things pretty well and experimenting is about engineering or proving a theory. Its cool there are still areas of fundamental science experimentation going on where we just don't get what is happening and have no idea what might happen with the next variant.
Except this has nothing to do with violating conservation of energy. Tell the sun you can't get a surplus of energy out of fusion.
No, no, no. It's not "almost" fusion. It is fusion. It is almost a fusion generator. That doesn't mean fusion isn't occurring. It means that the reaction is not self-sustaining. There's a huge difference. Saying that it isn't fusion is like saying that a match placed in a sealed jar and set ablaze using a laser isn't really fire because it consumes all the oxygen and burns out and there's no way to add more oxygen....

...but building one of those which will actually generate power is (unfortunately) financially out of the reach of any mere hobbyist.
Right! Which is pre-cise-ly why mere hobbyists were totally unimportant when steam engines were superseded by explosion/electric engines, when electricity superseded town gas, or when heavier-than-air craft superseded dirigibles, or when modern biochemicals/genetics/pharmaceutics took off after the '70s. And to the whole transistor -> chip -> microcompting discontinuity thing.
No 'amateurs' there, no sir-ee. No bycicle mechanics either. Or cofee plantation heirs engineering in Paris. Nooo-sir !
What's more, personal fortunes were much greater and lives-of-leisure more common (and acceptable) in those days than in our own more proletarian and democratic (or board-cratic) era.
So its quite improbable that anyone nowadays will have enough money and free time available to turn these 'hobbies' into 'serious' research. No free time. No wealthy patrons. And resistance is IR^2, damn!, I mean : futile. :)
