ABB says its the first commercial use- 1954. Wiki has the Russians using HVDC in WW2. Regarless the huge difference in transmission loss, 2 conductor instead of 3, both solar and wind generate in DC- makes HVDC first choice in bulk transmission. Thanks, I hadn't heard about the Russian reference. I...

going to the physics text book by Serway page 1179. Could you narrow that down? It would help if everyone was looking at the same thing. This book only goes to page 957 (see the "Look Inside" > Table Of Contents). College Physics by Raymond A. Serway, Jerry S. Faughn, and Chris Vuille (Ha...

Anyone here doubt how dangerous time travel could be?

rather than respond directly to political assertions in News, we can just point out that they don't belong there and limit the response to the effect that whatever political team the offender is playing for is demonstrating its inferiority by not playing by those rules. If enough of us are willing ...

HVDC has been around for years. I think the first actual installation was in the 50's (between a remote island and mainland Italy, if I recall correctly). ABB claim first HVDC in Gotland, Sweeden . I've seen that widely noted beyond ABB's site. It was underwater transmission sine that is one of the...

Indeed. This is not a very proessional behaviour from them. Moving from a 7.xx release to a 8.xx release should imply that all known 7.xx bugs have been cleared of. That is wishful thinking and completely different to how I understand how such things work - which is that major version numbers are i...

I thought the main problem with GPU codes were random errors in quality of the cards. For fast frame games an odd rogue pixel is not a problem but for simmulations it could be. Perhaps dependant on consumer versus professional workstation priced cards. i am a professional computer program btw, you p...

What effect does the electric field have on gyroradius?
The formula and description on wikipediaonly mention magnetic field.

Only had time to read it once and a quick thought... but it seemed that only the magnetic mirror effect was used to explain how electrons recirculate, slowing down and reversing direction when outside the magrid coils. While the magnetic mirror (and whiffle ball) effect keeps the majority of electro...

But (speaking generally) how many women would you find wanting to have those batches of kids?

Even if humans could live to 300 years, would women's fertility extend any further than today (and would they want it too?)
