Given the horrific costs of energy at the moment, you might be thinking about ways to cut your household bills. Maybe you could build your own nuclear reactor? [image by brndnprkns]

It’s not as crazy as it sounds. In fact, it’s so simple that a boy scout could do it, and sourcing your fuel materials is no more difficult than stumbling across them whichever scrapyard they’ve ended up in (if you can’t cut a deal with the whoever currently holds the post of Global Atomic Boogie-Man, that is). Try not to think about the waste problem, though; by the time your tiny reactor has produced enough to worry about, maybe someone will have decided whether storing it on the moon or an asteroid is the better option.

If you don’t have the spare real estate for a backyard nuclear fission reactor, I guess you’ll have to settle for a basement fusion reactor [via HackADay]. Impossible? Actually, no – though the “fusor” reactor type is considered to be effectively useless for large-scale commercial power generation.

However, the fusion reactor project proposed to the government by Research Councils UK would supposedly take only twenty years of R&D and construction before it could match the output of current commercial power stations [via NextBigFuture]… which is a long wait, sure, but an almost totally clean energy generation technology is surely worth it. All this assumes that the National Ignition Facility research continues to produce the expected results, of course; after all, fusion – much like AI – has been “just around the corner” ever since it was conceptualised.
