Actually only 7MW assuming a 4ohm speaker coil. Impressive but I've seen bigger bangs on youtube with even more energy https://www.youtube.com/watch?v=OC7sNfNuTNU
"Only" 7MW XD. The coil doesn't remain a coil for long, though, and it's hard to predict the behavior of the rapidly expanding ball of plasma.
styro was inspired by photonicinduction, by his own admission
