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.

Yeah, but he wasn't the only chef gooning the soup. By which I mean, don't over-credit any one bozo.

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.
