It's true that in some parts of the US electronics damage from power surges is a very real problem. Much of the midwest is wide open space with frequent lightning storms and most of the power distribution is overhead, it's not economical to bury it in sparsely populated regions. Lightning damage is rare where I live but even so I've seen a few appliances that had components vaporized off the PCB. I fixed a dishwasher that was a lightning strike victim, the fuse was missing entirely, only a black splotch on the PCB and a pair of splayed leads remained. The internal thermal fuse in the transformer primary had opened and part of a trace was blown off the PCB. This sort of thing is very common in the midwest, I've seen pictures of all manner of consumer electronics with vaporized traces and cratered parts. |

WTF does all this LED conversation have to do with the hyperloop? |

The subsidies made a prohibitively expensive product affordable for long enough to drive the manufacturing cost down. It's a form of the classic chicken & egg problem, a new tech is too expensive for people to afford it, because it's too expensive to sell enough of it to bring up the volume and lower the cost. People in general are notoriously short-sited and in the era of instant gratification and the extreme focus on quarterly gains it's only getting worse. |

I’m happy to be proven wrong, but I believe it’s just a handfull of small companies and some engineering student teams. --- Quote ---People in general are notoriously short-sited and in the era of instant gratification and the extreme focus on quarterly gains it's only getting worse. --- End quote --- Yeah, you got that right. I can only imagine where technology would be now if that had been the case during the 1950’s and 1960’s. |
