Ok. Laptop probably 50 watts. TV maybe 200.
The web says fridges run between 30 and 75 watts (average over the duty cycle)
3 hours x ~300 watts = ~0.9 KWh
Looks like he added a K prefix and he meant 870 Wh.
Maybe she looked like she knew martial arts and was about to leap off the walls, run across the ceiling and kick their heads in while doing cartwheels and dodging bullets. They've probably seen that police documentary series, Lethal Weapon.
It would still be detectable even with a notch filter. Back when it was still worthwhile to do, I built several stereo amplifiers, either from kits or designs in magazines. Getting rid of the 50hz hum was always the hardest part. Earth loops, wires passing close to the power, you name it, it would make the buggers hum. 50 hz notch filters were common in the cheaper designs, but they would only reduce it. You might gain 30 or 40 decibels with a good one, but modern signal processing will still pull the hum out of that no problem.
Good point, it is still a cyborg. But given the relative difficulties of production, and hardiness of the components, I consider a mechanical thinker wandering around in a meat body to be very unlikely. It would only make sense as an infiltrator (as in the movie) and would be easy to detect anyway.
I do think add-on mental components are eventually likely though, eg I would consider buying mods for fast calculation, perfect memory, improved senses, faster reflexes, etc.
Cyborgs are by definition cybernetics combined with an organism. They don't need autonomous or self-aware AI programming, that's what the Org part is for. The needed programming would only be the on-board control of the enhancements, and the interface to the controlling intelligence, ie: the translation from thought to action. I agree that the hardware is pretty much here, with the major exception of reliable, long-term, non-damaging, high-capacity, biology-to-machine interfaces. That's going to be the hard part. Messy wetware. Yuck
That actually might be useful in an urban low-tech fight. If you can pull the aimed fire while supporting infantry you could reduce your own caualties while pushing the enemy into revealing their positions.
1 inch sloped armor is going to stand up to a lot of rifle fire.
You could say, (puts on sunglasses) it's going to "tank" damage.
Just to be clear here, satellite to gound power transmission is microwave. This is a solved problem, efficiencies exceed 85% DC to DC. The lasers are for powering the lift vehicles, which means they will be in low earth orbit and capable of focussing a couple of gigawatts on a very small area.
Space based solar power can do it. Minimum investment to start it though, is tens to hundreds of billions. Requires a change in space access, favouring cheap over reliable, for cargo. The other option to get there is orbital laser assisted propulsion, which can make launches very cheap, but has a pretty big startup cost. (and worries people because of the honking big lasers flying overhead).
Even a lot of hands on jobs have things you can do from home. Paperwork, planning, estimates, reports, emails, etc. You may not be able to do the core work, but you can usually clean up a lot of the crap that surrounds it, which makes it easier to catch up when you do go back.
I think the usual argument is that all the volatiles condense out on the dark side. However, I just had a thought, this only applies to solid planets. What if there was a lot more water in the planets makeup, so that the surface was an ocean a couple of hundred km deep? I think you would end up with a hot sea facing the star, massive rainfall starting near the terminator line, and suficient glaciation to balance whatever water made it all the way into the dark side.
Also, one hell of an ice cap on the dark pole.:)
Larry Niven pointed out that a binary pair would be tidally locked to each other, rather than the star. While probably a lot rarer than single planets they would likely be a lot more comfortable too.
Your figures are off by a factor of 1000. Tera versus Giga maybe?. From wikipedia :
Last available year on wikipedia 2009:
USA = 3,741,000,000 MwHr/Yr
= 3741 TwHr/Yr
Which is :
3741 TwHr/yr / ( 5 KwHr/m2/day x 365 d/yr)
= 2049863000 m2
= 2050 square km
0r an area about 20 by 40 miles for the metrically challenged.
Still feasible, but a lot bigger.
There's no link to the actual yelp post, but the FA says she accused them of "losing" jewellery. It will come down to whether she said: 1. "they lost it", or
2. "they stole it".
1. is an acusation of incompetence, - possibly libel, hard to prove.
2. is an accusation of a crime. Libel if she can't prove they did steal it.
Easiest way to fix sea level rises is to dig two channels.
Connect the Caspian Sea and the Dead Sea (and the rest of the Great Rift Valley) to the open ocean and watch the water level drop.
If you have a travelling colony I really think you'd want to set it up so that you are in constant sunset. It is much easier to survive cold, and repair things in the dark than in an oven.
Oz is slang for Australia. Other side of a much bigger pond.:)
The used bookstores here were never in the good spots. They seem to be run by unusual characters because they want to, not just for the money. They are mostly still doing ok, at least compared to the new books.
The high margins on new books are because for a long time it was illegal here to parallel import, and they had a monopoly. A bit like the music cartels, they expected it to last forever. I remember a couple of cheap import chains that tried to open over the years, and were sued out of existence.
Hydrogen gas, because of it's low molecular weight, has a very high ISP. Given that extra fuel will exit in the engine exhaust, just chucking in enough to cool the airflow to operating temp may still be a net win. Also, your calculation only allows for heat of vaporisation. The H2 will also be increasing in temp by about a hundred degrees, which will absorb a lot of heat also. .029 g x 100K x 14 kJ/kg.K = about 40 kJ/kg. So it is going to be absorbing about four times as much heat as you calculated.
Where are you that bookstores are not going away? Here in Oz they are just about all gone.
Charging a minimum of $25 for a paperback novel that you can buy online for $7 (incl postage) is what killed them.
They blamed it on on-line stores not paying the sales tax, but that is only 10% here. It doesn't explain a factor of four.
I think Amazon hurt them, but the final killers were places like "The Book Depository" - I'm not certain, but I think they collate orders from all over the world, then farm out short print runs to digital printers, delivered direct to mail houses. No inventory, on-demand printing of damn near anything, but with just long enough runs to be really cheap.
And why is having robots do the grunt work bad?
Why not automate the hell out of everything and give everyone a twenty hour work week and ten weeks of vacation each year.?
More time off means more recreational activities, more holidays, economic boom for all the service sectors. Lower stress means reduced health care costs and probably just an all round happier society.
The average hunter-gatherer worked about five or ten hours a week to survive. With all our advances, it now takes 60 hours a week? That's bullshit.

I expect humans to be a bit less subservient to blind authority than dogs.
Your expectations are different to Police expectations.

Never before on wikimedia have there been so many searches for skittles and toothbrushes.
That's interesting. It's varying from 49.9 to 50.1
2% is a lot more variation than I thought they would have.

Quite a bit more was made by those selling booze and hookers.
Are you a large breasted woman?
A Dire Straights song comes to mind. No, it's not "Sultans of Swing".
Was it "Industrial Disease" ?
