The parasitic losses of DC over long distance is reason enough that it's not done
Siemens quotes 3.5% loss per 1,000km for +-800kv DC vs 6.7% for 735kv AC systems, exactly the opposite of your claim. I think I'll trust one of the biggest names in power over someone with a free bitcoin scam in their signature.
Then he started an incredibly stupid war in Iraq, which led to the rise of ISIS.
Yeah, but he wasn't the only chef gooning the soup. By which I mean, don't over-credit any one bozo.
launched a war against a sovereign nation thousands of miles away
I guess that's somewhat interesting from a logistical standpoint. And the regional politics of the Great Satan helping out the Saudis have some fun nuance. "Bush believed he was doing the right thing" is probably trivially true, but, again, omits an awful lot of Shiite/Sunni developments.
Which is, again, not meant as anything sort of an apologist play for W. And you can keep the brother, too.
Practical consumer-level devices do well to hit 20%.
No, 80% efficiency is pretty much the bottom of the barrel in switching mode power supplies, 95% from 20-80% of rated load is doable for around $200 for 1kw loads.
You're going to install a NEMA 14-30 and use a conversion cable to run your European kettle?
And what is the system efficiency of
Grid AC -> Battery DC -> House AC -> USB DC?
Often is a bit of a stretch, less than 1% of all high voltage distribution lines are DC.
HVDC works well for long trunk lines between a distant large power source and a population center, but it much less useful for a grid system with many interconnect points. That's why the primary usage has been between hydro plants and distant cities and for international interconnects (especially where the local grids of the two sides do not share a common standard).
LOL, more like it's audio for people who care about the quality of audio. I use the DTS HD-MA or TrueHD track with my receiver in pure direct mode so that I don't get all sorts of crap filtering and can just listen to the audio as it was intended to be presented (and how you'd hear it if you saw the movie in a theater, though generally with fewer tracks)
This is only Dolby Digital Plus, TrueHD support would have been much, much better and would have helped Dolby which has been losing the high end to DTS HD Master Audio.
