DailyDirt: Baby Steps Towards Fusion Reactors

from the urls-we-dig-up dept

Fusion is always just 30 years away, but we seem to be actually making some progress after decades of building huge superconducting magnets that will probably be impractical for producing net energy. We’ve seen Lockheed Martin and a bunch of fusion energy startups claiming to be able to control a fusion reaction in less than 30 years, but economically generating energy is still a distant milestone.

After you’ve finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

Re: all we need is solar, really.

We just need to figure out how to store solar energy. Damn battery technology.

I came across this recently, apparently saltwater batteries are a real thing! And Aquion Energy is a real manufacturer (as opposed to battery technologies that are only in the lab and might come out in 20 years).

They’re still kind of pricey, but they’re a fairly new company paying off their R&D and new manufacturing plant so I can wait.

But I mean, saltwater, what could be cheaper than that!

Management of solar energy is mostly already solved, and has been since the premordial ooze. The question is not one of storage, but of management.

The permaculture hippies are right on that particular subject. They typically don’t know why they’re right, but they are right. Probably 2/3rd of what we conceive of as an energy storage problem, is instead an entropy management problem.

Economics isn’t about dollars. It is about Watts. Economists generally study dollars instead of watts, which is how you can tell the difference between a sports coach in the game of finance, and a scientist.

After all, we know how to make fission reactors that work fine.

Nobody wants to build any, but if we really need the power we know how.

Not only do we have no clue how to build a practical fusion power reactor, we don’t have any need for fusion power.

We have plenty of power sources as it is.

Point being, they were built.

At the time of their construction it is most likely they were hailed as being indestructible whilst hushing critics, some being scientists, who claimed the safety features were insufficient.

Guess what happened next.

Why not build upon a known fault line, what’s the worst that could happen – right?

The cooling system was fine and had backup generators. However, there is almost nothing that can stand up to a Tsunami… certainly not a backup generator. They needed to heed the warnings left by the people after the last Tsunami and not build below the Tsunami water line clearly marked around the area. What good is a warning when it’s not heeded?
