Induction cooktops are ridiculously efficient at heating
- amelius 2y agoNice idea, but for generating that magnetic field you propose to use ... electric current? ;)
- klyrs 2y agoResponding to your question two above: You've probably seen multiple instances of this in your daily experience. A fuse is a thin conductor between thick electrodes. A light bulb is a very fine conductor between thick electrodes, encapsulated in a vacuum bulb. If you use tungsten electrodes, you can easily melt copper in the manner I've described -- that's how TIG welders work. Responding to your question about electric current: Quite simply, use leverage! Take a transformer with multiple (N) windings on the primary and a single winding on the secondary. Putting one (DC) amp through the primary will induce N amps through the secondary. With induction, you can use a low current to induce high current. Or correspondingly, transform low (AC) voltage to high voltage -- this is how high voltage power lines work.
- amelius 2y agoTrue, but something should be there to close the loop on that not-so-thin brick, and that something will get hot. That picture shows only a single brick, not a loop of bricks so something does not add up.
- klyrs 2y agoThe picture shows glowing hot electrodes; are you being deliberately obtuse?
