Or without any additional hardware at all
You can add an app to your smart phone that creates an ad-hoc mesh network on the 2.4Ghz ISM band that does the same kind of thing.

Based on photographic evidence of the crime then it's not a bad idea. The photographic database on which it feeds is the creepy bit. If a person is cautioned or convicted then there's a fair case for keeping a photograph on file. If there's only suspicion, or involvement in another case then I don't see it as reasonable to give the police the right to hold photos for that long.
And all their information can be encrypted with a key token so that even stealing the physical machine is useless.
Conversely paper documents can easily be digitised with a digital camera, and encoded data on them can be broken more easily as the current generation of ciphers aren't suitable for manual use (the older versions were replaced because they weren't strong enough to resist a computer attack).
The security of a digital system can be as high as your paranoia and budget allows while still being usable (perfectly secure systems can't be used at all).
"Meanwhile - feel free to replace your car with an electric one, because from all the pushing from politicians and "energy experts" you'd be forgiven for believing that the electricity they use just appears out of nowhere and doesn't have to be generated first......"
Power generated by renewables is intermittent in nature and hard to store. That's one source. The second (existing and well known) source is the large gap between capacity and demand over night. They already sell off-peak power cheaply in an attempt to get people to use it. You don't need any more generating capacity in order to cope with (IIRC) 30% of the country's traffic being electric powered.
There are these devices called EEPROMS that can store a few hundred K of data power free. A number of microcontrollers have them built in. That or there's something called flash memory, maybe you've heard of it? PCs tend to have a battery backed clock (powered by a small lithium cell) and EEPROM combined, so they stand for years without power and still start correctly.
The reason that devices like to be left running is something called heat cycling. Components expand as they warm up, and contract when they cool down. This results in failures due to mechanical stresses.
I would contend that nobody actually pays anything like £24k for an Astra, regardless of spec or list price.
It's not very hard to take the price of the Astra, with options, past £28K. The Beemer may have a list price starting below that, but for that you'll get 4 wheels and an engine. Everything else is an option.
You chose based in the purchase and running costs NOW, not when the government discovers that there are enough of them on the road to effect their revenue. When there ARE enough of them on the road to have that effect then the economies of mass production will have cut in, and they will be much cheaper to buy.
The main reason for the congestion charge is to cut pollution levels in Central London, not to do with traffic levels (traffic is actually flowing at the same speed, pretty much, as before the charge as they have introduced traffic calming to slow it down). EVs definitely help there.
And take a look at its price tag of around £34k for a car the size of an Astra. You've got to be a rich eco-warrior to be able to afford one.
Considering that an Astra with roughly equivalent spec (the 2 litre diesel automatic) lists at roughly £24k, and after government rebates the Ampera costs you about £28K, plus the facts that it costs about 1/3-1/4 in fuel, costs you nothing at all in road tax, is exempt from the London Congestion Charge and costs only 5% BiK tax if it's a company car (vs 15% for the most efficient Astra) means that you don't have to work hard at all to justify it as an option.
Take a look at the Vauxhall Ampera/ Chevy Volt. It's got a 50 mile range on pure electric, but also has a small petrol engine to generate power when the battery gets low, giving it a 320 mile range on a tank of fuel. Short to medium term that fixes your problem of range, and most people drive less than 50 miles per day so will use little or no petrol. It's also quite lively, with a 150PS motor and a sub 9 second 0-62MPH time.
running a green felt tip around the outside of a CD makes it sound better. Mostly because you think it does. There's probably some effect to the wow and flutter of the source, but high end HiFi folk can rarely spot the difference with their treasured improvement in a blind A-B-X test.
2nd generation Prius models have a large, multifunction screen in the middle of the dash that covers everything from the GPS maps through power usage to the audio system. You don't see too many of them embedded in the landscape or other cars because of it. Screens are only distracting if they are continuously updated with information not relevant to driving.
The other point about Li-ion cells is invalid also. The cells are very recyclable (95%+). Lithium mining isn't impact free, but it's one of the cleaner mining operations and it's certainly no worse than the extraction of oil.
You live in the Aereo warehouse? It's not a domestic location. The exemption is for personal home use. Under no stretch of the imagination could the Aereo warehouse be considered to be a personal home location. Renting a house or flat on the other hand doesn't change it's status as a domicile.
TiVo doesn't rent you the machine or location. They also don't insist that you accept their TV guide in order to get the service (though it becomes somewhat less useful). The only part of the equation that they are providing externally are TV listings (which I believe they pay the TV companies for in order to source them), everything else is within the user's personal domestic space and therefore covered by the exemption.
Stop me if I'm wrong, but that still involves rental. There is a special exemption in US copyright law for personal home recordings. The minute that a company starts involving themselves in charging for the ongoing provision of recording as a service then they're outside of that exemption.
The difference is that it's all done using your own kit without paying a 3rd party rental and without streaming over a public Internet connection.
Where Aereo messed up was the idea that they could profit from offering a service that Congress had already decided should be payed for (they had legislated retransmission fees). They tried for a technical loophole in the law as it stood and were always on shaky ground.
The answer is in the difference between peak and off-peak demand. Economy 7 has been around for years to try to encourage people to use off-peak power because it's expensive to have capacity that isn't used, even more so if the government insists on adding renewables which are intermittent or cyclic in nature. EV charging with smart chargers can help even out the troughs, and it is even possible for them to help with the peaks too by feeding surplus energy (as defined by the driver, and at a profit to them) back into the grid.
You can get a device with built in GPS and a degree of Arduino compatibility (you can program it from the Arduino IDE at least) for less than $30 these days. It's called a NavSpark, and it has a 100MHz 32 bit core with FPU so it's quite fast enough for this kind of work. Add a 10DOF sensor and a PWM controller and you should have change out of $60, plus a much smaller and lighter system.
Is how Google expect to launch that number of satellites for only $1bn. Iridium are working on a replacement cluster for their current network. 66 satellites are costing them $2.9bn, plus nearly $500 million for SpaceX to launch them. Google want to launch nearly 3 times that number.
So if we give it another 50 or 60 years of research we may be able to start an oxide based fuel cell with less energy? This compares to Lithium Air cells that should be in production in 5-10 years and have 3 times the energy density of current Li Ion cells (think of a Tesla model S with a battery pack half the current size and a 450 mile range)
The problem with solid oxide IIRC is that you have to heat it quite a lot before it starts to work. The cost of a start/stop is therefore high, making it poor for automotive use, though it's pretty reasonable for continuous draw uses. All of these fuel cell systems need an auxiliary battery pack BTW as they're quite poor at instantaneous demand.
@Aitor, given your own numbers a 4Kw installation would cost €8,000 to install. That money could have been earning interest (or, more likely, you have to pay interest to borrow it) so you can safely ignore the increasing cost per year as that is offset. If you can manage ENTIRELY on the power of your PV system then the average household would take 15 years to pay that back, ignoring maintenance and storage costs (you're dreaming if you think the system will sit there and need no work for over 15 years). If you can't store all of that power, can only sell the surplus at wholesale prices and need to draw from the grid at night then the time goes up significantly.
You're pushing it rather to describe the Xerox Star as a personal computer. It didn't use a microprocessor (using TTL logic, or bit slice chips in later versions) needed a file server and a print server to be any use and cost $16,000 just for the terminal, back when a secretary earned $12,000 per year.
The Apple vs Microsoft case proved that copyright wasn't a good way of protecting designs, so the Apple vs Samsung case was over two issues, design patents (the shape and design of the physical device) and utility patents (the way certain things were done in software), neither of which prevented competitors producing phones that were distinct from Apple's design, but Samsung decided they could make more money copying the iPhone as closely as possible.
The only reason they couldn't mention the F700 was because they tried to introduce it as evidence too late in the process. It was a misstep by their legal team, not anything malicious.
Once again, which was the patent for "touching a touch screen"? Nothing was as simple as that, and all of the patents were non-essential to making a smartphone.
Samsung got their chance to try to convince the jury that the patents weren't valid (for reasons like obviousness) and failed. A patent that has been upheld by a court is regarded as stronger.
BTW, which patent do you think was "touching a touch screen"? I think you'll find you're wrong.
asking for the damages to be reduced, it doesn't seam unreasonable for Apple to ask for them to be increased (these things cut both ways).
Given that Samsung have yet to pay up for the first set of damages it doesn't look like either side is in a hurry to settle this.
It's about phones containing features that are patented (like data detectors). It doesn't matter what they look like, providing they contain these features (which can either be worked around or removed, they aren't an essential part of a smartphone) then they violate Apple's IP.
I want a bloody desktop monitor capable of more than the bog-stock 1920 x 1080 they've been stuck at for the past decade.
You can't have been looking too hard. 2560x1440 screens aren't hard to find starting at about £400. 4K screens start at a little over £500 (though these are currently in limited supply).
Where did they ever say it was a "budget device"? They previously had been using last years model as their mid-range device and the previous years as entry level. The 5c took the innards of the 5, upgraded the LTE radio and a few minor bits and put it in a cheaper case. The 5 was dropped, the 4S was sold still as the entry level model.
Putting the iPhone 5c out as low cost budget device pretty much says it all
The 5c was never intended as a budget device, it was always targeted at the midrange market and Apple would have had to have been mad to contemplate jumping directly from high-end to budget in one step. The cost of handsets tends to be masked by the carriers including them in the cost of a contract. From that point of view the 5c costs a consumer about the same as a mid-range Windows 8.1 Lumia 930 (and it's not too far different if you pay cash too).
