I was just thinking the same thing. I remember visiting a hydroelectric dam as a kid where they had an exercise bike hooked up to a generator and a 60W bulb. Everyone there who tried it had a hard time keeping it at full brightness.
Agreed. A 4MW generator is going to run $1-2M, or you could buy one rebuilt for far less. For another million, you could install enough flywheel storage to last you until the generators can be brought online. Double it for added redundancy, and you're still talking 1/3 the upfront cost of the system.
The BBC only has distribution rights within the UK. They have sold those rights to a 3rd party in the US. They can't stream the content to you because they are legally not allowed to.
This has absolutely nothing to do with market exclusivity. DRM exists to maintain control over the content AFTER the user has downloaded it, to prevent the user from being able to store and playback indefinitely. Market exclusivity has been handled since the inception of iPlayer by IP geolocation lockouts. You have to be using a UK-based to access the content.
India didn't even get the good version, they got the crappy one that only holds 200kg with a 290km range. FAIL
The Russians have stricter export controls on anything with greater than 300km range. The Indian missile is intentionally limited to under that range to allow for continued technical support from Russia.
Or is it the casing around the propeller that really makes a difference ?
It's the casing that makes the difference. The casing makes it a directional 'jet', rather than just a propeller in free stream. That's why turboprops and unducted fans are generally not considered jets, despite being gas turbine powered.
The problem there is that a small jetpack capable of carrying a human being for long flights in Earth's gravity is physically impossible. No conventional fuel has sufficient energy density, and even if there were tiny megawatt fusion reactors, that doesn't relieve you of the need to carry reaction mass.
Actually, a turbojet pack without enough power to fly itself and a human for a halfway decent duration could be built right now. The problem is two fold. How do you properly handle CG, since a backpack would do nothing but forward somersaults until the pilot's appendages fell off. How do you handle heat, since the exhaust is going to be flowing past at least part of the pilot's body.
Also this jet pack apparently works with fans instead of jets. Which is probably good news for your front lawn and your calves.
This is still a jet. It still receives propulsion from a 'jet' of high speed fluid. The only difference between this and a high bypass turbofan is that it is powered by a 2-cycle gasoline engine, rather than a gas turbine.
That is the consumption of a fully outfitted system, using some 70 odd 42U racks. It's going to be lower thermal density than your average server farm.
Didn't the WSJ, or one of the other business rags have a service in the 90's where your computer would automatically dial into their servers early in the morning, and have a copy of the paper in your printer by the time you woke up?
Because accurate inertial guidance is cheap... Scavage the accelerometers out of a couple wiimotes, and after a half hour of flight, you would be lucky to guess your location within a quarter mile.
The Patriot is a 1500lb, Mach 5 missile, with over 100mi range, used against ballistic missiles and high altitude bombers. Of course its ridiculously overkill against a drone. Chances are it would end up causing more damage than the drone itself was capable of. The Avenger system uses Stingers, and while still expensive are only 1/100th the cost.
I have to shut it down because hibernation uses the battery and I need that power to last all the way to work.
Standby uses battery to continually refresh the memory. Hibernation dumps the memory to disk and powers down. There is no battery consumption save whatever is needed to run the clock.
Someone commented on the original article about the Samsung 'UTN' and 'UXN' professional displays. This one results in less than a quarter inch edge-to-edge.
A head on collision would be a spectacular impact at 14km/s, that would destroy both objects and spread a huge cloud of debris in all directions. A glancing collision would be a spectacular impact at under 1km/s, that would destroy both objects and spread a huge cloud of debris in one general direction.
Why would you have to be in a higher orbit? You ablate from the front of the debris to slow it down, not from the top to push it toward Earth. Pushing something towards Earth would simply add energy, and put it in a higher orbit.
You need an absolutely massive amount of energy to vaporize something with a laser. The current concept of a 'laser broom' is to use the laser to ablate a small part of the debris, causing enough thrust in the opposite direction to eventually deorbit it.
In the past with XvMC, this was true. XvMC only offered the iDCT and MC parts of mpeg2 decoding. VDPAU is a complete offload, start to finish. You give it the raw compressed video stream, and it handles everything from decoding, deinterlacing, scaling, colorspace conversion, and dumps it onto the graphics framebuffer without it ever coming back across the PCIe bus. I believe VAAPI and XvBA also operate in the same manner. The CrystalHD stuff is a bit different in that you put compressed video in, and get decompressed video out, which you have to then do deinterlacing (if needed) and push onto the graphics card for scaling and colorspace conversion.
The ICT will be enforced on any display that does not support HDCP. That includes all VGA and some DVI monitors. Of course if you're using 'analog composite', you have already constrained yourself to 480/576i.

This sounds no different from VASCAR which has been used since the 60s.

Modern stingers are dual mode, IR or UV optical.

There have been at least two TV shows that I'm aware of.

They will not ban VGA, however any video with the ICT flag will be downscaled to 480i, before being upscaled back to your output resolution.
The ICT will be enforced on any display that does not support HDCP. That includes all VGA and some DVI monitors. Of course if you're using 'analog composite', you have already constrained yourself to 480/576i.
I doubt that this will be met with much resistance due to the fact that component only give you 1080i, and HDMI delivers 1080p.
Component video can do 1080p too.
That's pretty much how I felt about Sunshine. I was getting into it, right up until it turned out to be another Event Horizon.
