If I build one of them it'd cost half a million dollars. Would you buy a battery powered car at half a million dollars?
If I build 100,000 of them they'd cost twenty thousands dollars.

Solectria are a small company, they can't afford the manufacturing capacity. Note that their Solectria Force car has a 250 mile range.
We keep hearing that the technology isn't up to it. Simply not true, that problem has been solved. The problem is manufacturing investment.

Yup, it's true. A battery powered 4 seater electric car was developed in 1997. It had a range of 373 miles at a steady 55mph. That's as good as my petrol car. It would also do 0-60 in 7 seconds which is a damned sight faster than mine. Looks not bad too.
NiMH batteries, good for 100,000 miles worth of recharges. Right *now* there are lithium ion batteries which have a significantly higher energy density than NiMH and there lithium sulphur batteries on the horizon with higher still energy density.

So... Where are the production models of all these electric vehicles which would allow me to run for a week on a charge and then charge it up on solar power? It's almost like there's some vested interests out there who don't want to see them on the streets.
Because it's built into my phone, I've always got a usable keyboard with me and a hierarchical note management utility (myList). As well as a decent voice recorder, wordprocesor and the rest.
Would you believe the government have classified them as motor vehicles, which they are, but FFS!
You need a license and it has to have type approval and be taxed and have a registration plate which means you need insurance etc. None of which are going to happen.
Because you can scale an A4 page down to A5 size and print two of them on each A4 sheet and they fit *exactly*. Saves paper.
If you are a *real* skinflint and have good eyes you can scale down to A6 and print double sided. It works quite well with a decent laser printer.
The reverse is true obviously if you want to scale up. You can tape (A4 usually because it's the most common) pages together to make A3, A2 and A1 sheets and it all fits together exactly.
Having said that, I kind of assumed that the same thing applied to US paper sizes. Surprised it doesn't.
How does evolution work if you keep saving people who have no sense of direction or danger?
Humanity would end up unable to read maps and work out where they are trying to go... Come to think of it, I think there is evidence that has already happened to women.
Hence the Internet. The beauty being that you have 1TB worth of stuff to watch in the meantime. There must be something decent on for it to record in the weeks it takes to go through it all.
Course, this is where Tivo's autorecord feature comes in, though with a Bayesian discriminator to decide what it should be recording.
Blair got 42% of the vote, 58% of the people didn't want him. He has a majority of around 65% which allows him to push through just about any policy he likes.
Rather than giving someone your timecard, you just make a mould of your finger and they press that against the fingerprint reader.
Not only can you make a mould of a finger from a willing participant (and why not if you want to commit fraud against an employer). You can create fake fingerprints from residual prints that someone has left behind.

Cry To Beat Iris Scanners

Both Labour and the Conservatives support the introduction of biometric ID cards. Labour because they believe it will give them control and the Conservatives because of the amount of money their contributors are going to make while rolling the system out.
We're lucky in that there is one party who are definitely against ID cards, the Liberal Democrats, but realistically, they don't matter. The UK has an election system which favours the largest minority (35%-40% is enough), handing them a disproportionate majority in parliament (around 60%).
P.S. For UK residents, the BBC has a campaign page for those who are against ID cards:
Iris scanners have a failure rate of around 4% -> 7%. This is a failure to identify a legitimate person against a *previously stored scan*. I.e. the scan stored in your biometric card or the scan stored in the government database.
Fingerprint scanners have a failure rate of around 2%.
There will be a couple of years of turbulence as the economies are integrated but unless the US swallows Canada and Mexico it's going to be playing second fiddle in the mid future.
Quite true and rather a confusing situation for everyone for a while. Interesting you talk about territory when the EU is a political entity. It's the people which matter. About 2/3 of the countries have joined.
The EU is now 450 million people, just two weeks ago it was 380 million. In 3 years it will be 480 million when Romania and Bulgaria join. Then it will be just Switzerland, Norway, the Balkans. I suspect Russia will never join and it be a good few years before Belarus and Ukraine join.
In 50 years the EU is going to be a unified superpower and the EU and Europe will be synonymous. Hopefully they won't forget the reason for it existing in the first place.
The UK went metric for most stuff a couple of years ago. It'll take a few years for everyone (possibly a generation) in the UK to switch over and there are a few odd things like miles which will take a while to go away, but it's happening. America will convert to metric eventually.
Decent compressors are around 70% efficient. The air heats up due to the ideal gas law as you increase the pressure, the temperature rises naturally, *quite significantly*. In fact, the temperature in the tank would reach several hundred degrees C just through the act of compressing it.
The problem is actually cooling the air (this is why compressors get hot BTW, it's not because they are using energy and wasting it as heat, it's because they compress the air to a high pressure in the cylinder and then allow it to decompress into the scuba tank/tyre/whatever). You would have to siphon off the heat to use elsewhere, say for heating hot water or central heating. It means that when the air is used to power the generator it would cool as it decompresses, probably well below 0 degrees C, handy for air conditioning.
I don't see a big problem with a big air tank though I'd probably bury it to save real-estate, not much more of a problem than a tank of petrol, hydrogen or propane. Scuba tanks are filled to 300 atmospheres and people wander around with them strapped to their back.

The parliament seems to be a puppet organisation with no real power. I think it may be best to avoid it until there is some real democracy.
I'll be emailing my existing MEPs with that sentiment and my voting plans.
