Let's face it, even the most reserved and sophisticated of us will drop what we're doing and run to look if we hear an explosion or that loud zap we know means that high voltage has escaped the confines of its transmission lines. The allure of that plasma arc is just too strong to resist. Unfortunately, or possibly fortunately, we aren't often in the right place at the right time to witness the magnificent arcs first hand.
Today, I'd like for you just to give in and indulge yourself in some mindless entertainment. Allow yourself to gawk at these power line failures, guilt free. A word of warning before you begin: many of these videos include cussing. I have avoided any videos that show anyone getting hurt, so you have no need to worry about that.
See? That felt good didn't it? Continue on to the next page to see more -- you know you want to.
Yes, I live in Oz and all new estates now have underground power (have for 20 years now) but the gut feeling I have is that if the whole city grid was underground that the capacitive load would be horrendous. We often have power outages in summer because when the government privatised the power distribution maintenance and infrastructure planning (forward thinking) died.
I wonder if it's feasible in this day and age to run high voltage DC underground (to offset capacitive losses that would be higher) and then convert to lower voltage AC where it's needed? It would help reduce arc over events due to ice & trees etc. or downed poles due to vehicle accidents. I wonder what the leakage and conversion losses would look like in comparison?
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
