Simple compressed air works well too for avoiding friction across large surfaces - think hovercraft. The air escaping from the perimeter is relatively small compared to the surface area "levitated". Bascially it's scale working for you.
The picture showed a large vertically arranged wind turbine (VAWT). One scaling problem of all wind turbines and VAWTs in particular is that the RPM drops as the mill gets larger. The alternator required to extract the power from a slow moving but huge torque shaft becomes unwieldy. Perhaps the alternator is built into the magnetic levitation system?
Guards only knew about you if they saw you (line or sight) or if they heard you shoot your gun. You could also use an enemy uniform so that they would ignore you. That was about as stealthy a game dynamic as was possible in 1981. The sequel in 1984 added a dagger for silent kills
Stealth was rewarded over killing. The trail of bodies (supposedly) caused SS to hunt you down. They had bullet proof vests, grenades, ignored your friendly uniform and chased you room to room - a very nasty surprise. SS definitely showed up either way, but perhaps more often if you left a trail of bodies.
The axle and bearings have to be able to transmit the torque for the angular momentum to cancel. High RPM flywheels use magnetic bearings that will not handle that force - not even close.
As you are probably aware, Flashback was a "sequel" of sorts inspired by "Out of this World" (OOTW). OOTW had no dialog or subtitles, fit on 720k disk and had 2-d line art graphics. It was also one of the most immersive, creative and thoughtful games I have ever played. Flashback had better graphics and similiar gameplay but lost the awesome weirdness and surprises of OOTW - in my opinion.
I just wanted to highlight Flashback's inspiration.
Some articles imply that there are ways of sensing whether the universe has needed to resolve the white/black state of the rock without looking inside the pouch. By entanglement it is possible that a distant person checking their rock color will force resolution of your rock color. The information "transmitted" isn't white/black, it is color resolved/unresolved. That seems to be enough for instant communication, but something gets in the way. I can't rememeber the details of it either - IMNQP (I'm not a QED physicist).
It isn't that it's DC. It is that the DC is low voltage compared to 110V AC. Wire losses are inversely proportional to the quare of voltage so 110 AC is about 100 times as efficient as 12V DC (Think I^2xR for the resistive power loss). It is very difficult to change the voltage of DC and very easy to do it with AC. For that reason high(er) voltage AC is preferred for power distribution.
HVDC makes the most of the voltage limit in the wire insulation and the relative lack of inductive losses to ground from the magnetic fields emited by AC lines. The voltage quoted for AC is actually the DC voltage amount with equivalent power. The true AC voltage oscillates with an amplitude about 40% higher (and 140% lower) than the quoted figure. The peaks would exceed the insulation limits and corona discharge into the air.

www.fieldlines.com is a good forum for off-grid issues. The site sponsor builds his own wind turbines - big ones. His latest has a twenty foot diameter and produces all the power he needs.
The best off grid systems combine two or more sources of power. Wind, solar, microhydro - pick two and then get a back generator. Having more sources reduces the need for batteries, which is arguably the weakest part of any off grid system.
Concentrating has efficiencies that you cite but also costs. The mirrors have to track the sun to produce any power. The tracking mounts and controls are expensive. Off axis the mirror directs the light away from the target cell - no power - so tracking is critical.
Non-concentrating panels produce more power if they track the sun but still produce power according to the cosine of the angle between the sun and the panel if they don't. Also direct panels can get some power from diffuse sun, such as on a hazy day. Contrators can only use direct sunlight.
Excess heat is radiated into space. Global warming is thought to be caused by greenhouse gases changing the equilibrium that determines the "excess".
Romans would make ice by keeping the ground in a pit cool during the day and allowing the heat energy from buckets of water in the pit to radiate into the cold night sky. As long as humidity was low enough, they made ice!
So the issue isn't generating heat, it's greenhouse gases trapping the heat.
Maybe to entice people to keep playing them in Street Fighter or some other competitive arcade game? Better to let them win one round so that they do not see that it's hopeless.
US patents may be granted without a prototype. Plenty of patents are issued for products that are "hypothetical" in the sense that materials or other engineering challenges remain to be solved. I'm not agreeing with that protocol, but again, hypothetical is fine in our system.
Some purification technologies also need less circulation. That would be worth looking into. You can also look at using a timer to run the pump at night for a TOU pricing improvement.
That assumes the price of electricity doesn't go up. It you charge an interest rate you ought to credit a cost inflation rate. I think the cost will rise faster than a typical mortgage rate. Also the variability is asymmetrical.
Electricity costs can't drop below zero, any drop is unlikely. They can however double and you'll be waiting in a long line with everyone else to buy and install those panels.
The concern involves the aggregate energy consumption of this power transmission sheet versus wall warts. You and I can us a power strip for our wall warts and diligently switch off the power on the strip. Great. What about the other 500 million that don't?
Wall warts are probably worse for wasting energy, especially since they stay plugged into the wall even when the gadget is not recharging. That burns energy 24/7.
One pad - even with transmission losses - is probably better than the typical 3-6 wall wart chargers in use at a given time.
It's important to note that flourescent bulbs contain mercury VAPOR, not the liquid stuff. It is the vapor that is dangerous. The stuff in thermometers hasn't vaporized and is therefore much less dangerous, microgram for microgram.
"Clean up" should be as simple as openning a window, though. I guess I'd check that the draft would pull air out of the window rather than in.
Oh, and don't cry about sending the mercury into the environment. Your neighborhood coal plant is doing that times a billion on your behalf.
This is so true. We had a totally different mindset towards rolling out new technology back then. It was a nation security crisis if the Russians had mastered something that we didn't. Because of that urgency, we didn't mess around.
Now it feels like many new technologies are "optional", would be great, etc... Where's the crack team from skunkworks to figure out if this fusion tech has legs?
From websites alone Blacklight Power LOOKS much further along. Of course I think BLP is a sham. They do have lots of pretty pictures, and some data that is not well recognized in the scientific community. Ten years later and they are still in the pretty picture business... That's why you don't just "throw $200 million" at these projects.
Mount the steel door frame so that it floats on automotive valve springs. The springs are pre loaded to push the frame flush outside but with about three inches of travel towards the inside. That way, when rammed, the door gives and the masonry/conrete doesn't take the concentrated impulse of the ram. Apparently valve springs are quite stiff so that using several of them will absorb the energy of a very heavy ram.
This suggestion was published in one of those counter-culture Paladin books.
That is actually a pretty good idea. Laser eye surgery is sometimes done with one eye biased for near vision and one for distance vision. That seems to be a greater compromise in depth perception.
In any event I don't think depth perception would be effected. It doesn't rely on color. It relies on relative size and orientation.

Castle Wolfenstein, 1981 for the Apple II
Castle Wolfenstein is much earlier and used stealth as a key game mechanic. It came out for the Apple II in 1981. Beat that...

A robotic "bumper boat" could push / turn away approaching craft to enforce a perimeter.
It could further escalate the altercation by pumping water into the boat, harpooning it, fowling the propellor, throwing a net, etc...

You can go one better:

LOTR and 300 are both movies. That said, I still doubt the models are the same.
Funny choice considering that the Greek empire did eventually fail.
