So far, he hasn't really done anything except prevent a bunch of jobs from leaving the US.

Looks like you're swallowing the output of Trump's propaganda department hook, line and sinker.

Now, other than that smoke screen, what he has actually been doing so far is to tap into the drain spigot of the DC swamp to fill up his administration. This story is yet another example.

Your slip is showing.

If you're going to make insults, you better make sure you're right.

First of all, joules are energy and TW are power,

No shit, Einstein.

so your conversion is nonsense.

Are you high?

Secondly, assuming you actually meant TWh, not TW,

You assume much, Grasshopper.

you are off by several orders of magnitude.

Nope, you're just highly confused.

The total worldwide electricity production in 2012 was 18,000 to 22,000 TWh

Why use a stupid unit like TWh/year? Hours/year is a dimensionless number. Just use the plain SI unit: 22,000 TWh/year == 2.5 TW. Which, as I said, is a fraction of the 16TW total energy use.

648 MW ...
That's a hell of a lot of land for .0007% of India's electricity consumption, based upon 2011 figures... at that rate, they'd need to cover a fifth of the country with PV panels, never mind night time load.

Your numbers are way off.

648MW / .0007% = 92 TW

All of human civilization consumes about 500 exajoules of energy per year, which is only about 16 TW. (Of which electricity is only a fraction, BTW)

Covering 1/5 of India with solar panels would actually potentially generate enough energy to power the entire planet several times over.

"It used to be the case that the computer you bought came with schematics and"

This is just as wrong. Insofar as the percentage of the population that bought these computers was vanishingly small, instead of ubiquitously large. Apples and Oranges. Different day and age and world. There was never a time that ordinary people purchases such things. It's a nice fantasy though, I'll give you that.

Plenty of ordinary people bought the original IBM PCs and PC/ATs. They didn't come standard with the schematics, but you could buy technical reference manuals from IBM which included both the schematics and the BIOS source code for the systems.

Maybe few end-users made use of the available info, but it did ensure that 3rd parties could create a large ecosystem of compatible software, accessories and even competing computer systems. This greatly benefited the end users, whether they cared to dig into the underlying technology or not.

So what do you do with all the old supercomputers when they're too big/power hungry vs performance? Helluva paperweight.

If they're anything like me, they'll put it on a shelf in their basement.

25 years later, they'll try turning it on again just for fun. One of four things might happen, with roughly equal probability:

  • 1. It works fine
  • 2. It boots, but acts really flaky with strange characters on the display
  • 3. It's a brick
  • 4. Some component goes up in a puff of smoke; goto 3

Comment Re:Had paper ballots here ... (Score 1) 286

We have the same type of system here. It makes total sense and couldn't be easier to use.

The only disadvantage I can see with it is that they sometimes make a mistake with the pre-printed ballots and have to scramble to get enough correct ones made up. However, if that's a problem, I think that just giving each polling place a laser printer and having them print them on demand would be better than getting a whole bunch of hackable electronic voting machines.

Without giving the voltage, those numbers are pretty meaningless. Power = Volts * Amps

Lightning has a huge power at 2A because it's millions of volts.

A high-end microprocessor can draw about 100A, but only at a little over 1 volt.

Your circuit breaker will trip at 15A, but at 120V. That's 1800W. If this capacitor is only charged to about 1.5 V like a typical battery, the 600A would only be 900W.

Thus, you could easily charge it from a standard outlet. It would require a beefy power supply similar to those in large servers, though. I think that most people would opt for a cheaper power supply that could still charge their phone in a minute or two.
