A YouTuber Puts a Billion Watts Into a Speaker and Keeps the Power Grid on Edge
Billion Watts in the Speaker [video]
A long-awaited video from a maker known for extreme electrical experiments has Hacker News readers celebrating that he is still alive. Commenters swap stories of their own high-current builds — one recalls 100A continuous at 24V — and recall his strange 2020s detour into a supposed "free energy" gyroscope device, which they now attribute to distress over his wife's UK visa troubles.
If anything, we're all celebrating he's still alive!

Good to see him doing well. I think he single-handedly keeps the national grid on their toes.
The most powerful circuit I ever made dealt with 100A continuous and 200A peak at 24V, this guy is is simply on another level I can't even begin to wrap my head around.

Just by reading the title I've thought - it must be Photonicinduction! Glad to see that I was correct. True madlad!

The mapping between audio gear and the power grid is pretty close. AC power and audio waveforms are basically the same thing. If you connect a speaker directly to normal mains power, it will operate briefly before burning out. You'll get a very loud 60 or 50 hz test signal depending on where you plug it in. There are some drivers large enough that they can withstand this power level indefinitely. The car audio market has some pretty crazy designs.
There are pro audio amplifiers that are capable of producing >120v RMS at their output terminals. I would be much more interested in seeing a youtuber purchase one of these and attempt to run a bunch of household appliances using it. Blowing up random shit with ridiculous amounts of power got pretty old for me as a form of entertainment.

This is not really a HN subject, I think - that said, I really love this dude.
Popping up in my subscription-feed after 5 years was a highlight <3
And it def. IS nerdy :D
