This is actual snake oil

O.o

What the fuck kind of snakes do you have living around you?

The headline’s a bit misleading. The drive is a plasma thruster, and the company found that by adding Boronated water to the exhaust the plasma would fuse with some of the boron creating a kind of afterburner effect, not a sustained fusion reaction. It’s kind of interesting as a way to boost the performance of the plasma thruster, but not “OMG it’s a Fusion Drive!!!” interesting.

Technus@lemmy.zip on 24 Mar 2024 09:12 next collapse

Yeah, that’s the fault of the article author. The actual press release uses “fusion-enhanced” which is a lot more honest.

To be fair, they’re quoting a 50% increase in thrust so it’s not completely clickbait to say “fusion powered” but it definitely does give the wrong picture.

Imagine all this work/research on fusion and some dudes like oh yeah my space engine does that

Fusion is easy. Getting net energy out is hard.

Wasn’t there an rocket concept like that from the 70’s, using the freed electrons for containement or something? I saw it once on Wikipedia and then never found it again.

user134450@feddit.de on 24 Mar 2024 21:31 collapse

There has been some fusor research going on for decades. The issue that killed that direction of fusion research was ultimately that the electrons do not behave as the initial simple models suggested and in the real world the power loss from the fast electrons is just too big for any reasonably sized device to allow for self sustaining fusion.

Mirshe@lemmy.world on 24 Mar 2024 22:12 collapse

Basically this. Look at all the big fusion reactor projects - they’ve been going for decades and JUST NOW hit a very miniscule amount of net output within the past several months.

JayDee@lemmy.ml on 24 Mar 2024 09:16 next collapse

What is this cube and how does it relate to the drive?

Etterra@lemmy.world on 24 Mar 2024 10:36 next collapse

When you plug two of them into each other it goes twice as fast.

And 3 to make a sun into a torus.

intensely_human@lemm.ee on 25 Mar 2024 02:24 collapse

That’s what it looks like when it’s about 50% complete. At that point you need like 2000 steel plates and it’s a pretty slow grind.

Etterra@lemmy.world on 24 Mar 2024 10:38 next collapse

But do they stack in my inventory?

intensely_human@lemm.ee on 25 Mar 2024 02:22 collapse

Only the small grid version, which we haven’t unlocked yet

The first step in designing a fusion reactor is picking where to hide the power source

I beg to differ. I present - the Ford Nucleon. en.wikipedia.org/wiki/Ford_Nucleon

MedicPigBabySaver@lemm.ee on 24 Mar 2024 22:05 collapse

This was a concept. The linked article claims demonstration. Big difference.

It was a joke. WTF

BreakDecks@lemmy.ml on 25 Mar 2024 08:45 next collapse

Not exactly inspiring any confidence trying to pass that AI-generated monstrosity as a photo of the device.
