No, not the risk of buying stocks or boys playing with matches...

These guys have a 60kW induction furnace and make their own magma to squirt water on to watch how it explodes!


Doesn't sound like a bad job, eh?

I didn't see the specifics but I wonder if they are using fresh or synthetic sea water...

That 1.0235 times heavier with the predominate component sodium ions probably makes a difference. ;)

I'm surprised that rocks melt at such a low temp. Steel just starts to have pockets of it melt at that temp, I would have thought a natural ceramic would be more. I can't imagine getting spatter on myself.

Wow had no idea you could reach that point with induction. It's something I kinda want to mess around with one of these days. 60kw though, might need a hydro upgrade for that one. :p And to win the lotto to pay for that bill.

It really depends on the rock composition. It wasn't provided in the video. Pyrometer readings weren't shown either so it's hard to say. One thing's for sure though; it was hot enough to burn your leg off! :p

Imagine if they had a sufficient furnace and mass to create lava bombs that could be launched a few hundred meters in the air! :D

Induction can go much higher but it's probably more efficient from operating cost perspective to use a gas fired burner. And much easier for a backyard experimenter. 100# propane cylinders are cheap and easy to transport and will provide plenty of fuel for hours long runs. Whether you're heating up scrap to displacement castings of ant colonies or casting parts for engines, it'll do just fine. ;)

If one did have three phase power on premise with a 100kVA or larger transformer to supply the furnace operating costs for four hours wouldn't break the bank. Unless the bank is really small. ;) 60kWx4h = 240kWh. At higher rates (net $0.18/unit) that's $43.20 for a furnace run. A 250mbh burner (output) can run off a 20# BBQ type tank but it won't run that long due to pressure issues. They ice up very quickly under such flow. That's the nice thing about electric - it just works. :)

Did you change your avatar??

I don't think so.

We had induction heating the round stock each being 8"-11" long and 2 - 2 1/2 dia. It took maybe 45 seconds for steel to go through 3 two foot long induction heaters and come out at 2250F.

I should probably change that at some point. But if I wait long enough then I may as well leave it on for next Christmas. :D

It's getting a bit close to summer, summer goes by super fast, and then at that point it will be almost Christmas. So it's technically almost Christmas.

Of course if you want ferric magmatic flows just overstoke a decent sized EAF and keep the power on! :Q

Imagine having a 100+ GW system going fully pyroclastic.

Infallible logic :p

I mean this literally: what the hell :fearscream: And 100+ Gigawatts? :fearscream::fearscream::fearscream:
