Well fusion is much better than fission, not self sustaining thankfully!!

30 September 1999 Tōkai At the Japanese uranium reprocessing facility in Ibaraki Prefecture, workers put a mixture of uranyl nitrate solution into a precipitation tank which was not designed to dissolve this type of solution and caused an eventual critical mass to be formed, and resulted in the death of two workers from severe radiation exposure.

It’s even easier and cheaper to get fission going for a bit and you get to see the flash

hold on alarm bells ringing

theres a forum where other people show what they have been doing with their fusion reactors??

ffs hold my beer….if you see a flash from sheffield it wasnt me

Pah…..that’s nothing special….at 13 (and fascinated by chemicals)  i/we were firing turnips the length of a field using the tried n’ tested fertiliser bomb method (god bless the anarchist cookbook), that was back in the 80’s mind you, and in the wilds of argyll so we were left to find our own entertainment, and with a farm and fully equipped engineering workshop we eventually managed to blow the bloody barn doors off…..and the roof….and the walls……..and a pole mounted transformer which knocked out the power supply to the entire achnamara and castle sween area.

No more fun n’ games/explosions were allowed after that (sad face)

Fission – the one where sustaining it ends up really bad

Ahem, you appear to be confusing criticality and supercriticality. Criticality is a sustained and steady reaction whilst supercriticality is an increasing reaction which, obviously, is bad unless under control.

Fusion isn’t the nice clean energy it’s made out to be either, I for one wouldn’t be volunteering to climb into a tokamak but I would take a dive into an AGR.

“He transformed an old playroom in his parents’ house into a nuclear laboratory with $10,000 (£7,700) worth of equipment that uses 50,000 volts of electricity to heat deuterium gas and fuse the nuclei to release energy.” Okay, I don’t mean to question other people’s parenting and budgets, but…

Talking of smart 12 year olds, I was performing due diligence before a customer meeting this week. One of the meeting attendees and it looks as though someone I’ll be working with a bit more is this guy:

I bet it’s even been fact checked!

As it says in the article “However, scientists are likely to remain sceptical until Oswalt’s workings are subject to verification from an official organisation and are published in an academic journal”.

Achieving fusion per se is relatively benign and only results in low level radiation – it’s getting more energy out than you put in that’s difficult and potentially dangerous.
