Here you go, those are $100 bills.

When I talked to one of our VAR's he said that one of the local hospital chains was one of his best and worst customers, best because of all the expensive gear they bought, worst because they were so demanding. They actually paid to have trenching done to make sure that their backup link at one facility went out a different CO which was on a different uplink facility (ie truly divergent paths with no single mode of failure), and that was just for PACS, not telesurgery.

Couldn't find any numbers for 800kv AC, the Tepco 1,000kv AC line is >5%/1,000km so the extra 10% from 735 to 800 isn't going to help much.

Ah, I had forgotten about 6-15R, whenever we deal with 240V it's always L6-20 or L6-30 twistlock or C13, neither of which would work in a kitchen. I do see you can get 6-15R in GFCI which is good since that's required in kitchens.

Wouldn't pass inspection in the US since they're not classified in the NEC.

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.

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.

You are aware that plenty of people are monitored for their entire shift in much less safety critical jobs, like bank tellers, grocery or retail store cashiers, dock workers, etc, yes? As to the speed being controlled by computer, they've been working on that for some time, but apparently the radio network to convey all the necessary information to the control box is massively behind schedule.

As far as anybody can tell, though, we could lose mosquitoes entirely with no big secondary effects. So let's get on eradicating those fuckers. Way more important than anything the Gates foundation has claimed to do.

Considering one of the pieces of the Gates Foundation anti-malaria campaign is sterile mosquito introduction in an effort to eradicate the local population I think you're a bit off there.
