Electronic Fuse

so when one component burns out, replace the whole circuit?

This is reasonable in our times. Look for cell phones as example. They are state of art . Our best knowledge most precise miniaturization. Our proof than we tame frequencies in the range where reality is like another world and we are persuaded to throw them to trash bin when a single fuse is burn or when they are one year old. Yes that's reasonable when our greatest proof of ingenuity our technological prodigy is thrown to fat ugly stinky pack of pigs. That's how we respect our work and anything other. We have no respect but we are learned to have no respect. To throw out equipment not because it is truly outdated but because companies must force us to do so because if we not do this then a lot of ppl will lost job due to bankruptcy . Cars, electronics, computers especially they are at point with no other options. Or they force new item and make older one at all cost unusable, or due to sale rate drop company simply vanish within a year. How many resources and usable power is waste in this process. How this demoralize ordinary ppl cuz they learn that nothing have any value this is problem of greatest importance with no solution

I appreciate the comments out there. This ckt was a prototype for a larger scale for a 50000kwh green house out in the outskirts of nowhere. Its not like i can go to the store to buy a fuse. Just wanted to test the app. Impressed maybe. Had to redesign the indium platform to redirect heat.
