"In Europe you can find lots of small cars that have a comparable MPG"
Can you tell me please? I looked amoung all of the manufacturers last year and couldn't find anything actually on the market which was as efficient. The diesel in particular does 84mpg.
The evidence is that there is precious little prepresentation, or in fact democracy.

Anyway. Virgin Galactic as part of Virgin group is a global company, there's no particular reason to run the company from America, launch from America or even to build the craft in America.
Rather than RAID, they need something like AFS which would allow a bunch of servers to be knocked out but would still continue to function normally. Sprinkle them around half a dozen countries and taking out your organisation becomes extremely difficult, it just needs one to survive.
Hmmm, The FBI as a Disaster Recovery scenario, who'd've thought...
Unfortunately there's a crime the UK called Going Equipped. What this means is that you are equipped to steal something and you have the intent of doing so (crowbar, skeleton keys, screwdriver etc).
It could be that the installation or use of software like ANts could be construed by the CPS as going equipped, though it's civil offense to infringe copyright here, for the moment.
First point is that 200 W/m is what you get after the 20% efficiency of the cells. There's on average approx 1kW/m insolation.
Second point is that electrolysis can be 98% - 99% efficient depending on the rate you want to do it at and the cell design.
Third point is that current generation Li-ion batteries can have a higher energy density than hydrogen at 150bar, approx 405Wh/l. PolyPlus have a Li-S battery demonstrating 420Wh/l.
Your internal combustion engine is only 25% efficient, the gearbox, transmission and traffic/idling drop that efficiency to around 10-12%.
Current lithium batteries have a broadly comparable energy density with a tank full of compressed gaseous hydrogen (or are you going to spend extra solar energy liquifying it?), electric motors are 90%-95% efficient and batteries are 90%-95% efficient at storing the electrical energy.
So, are you going to use 10% of 400Wh/l or 80% of 250 Wh/l?
Bottom line is that a current generation electric car (Say a Solectria Sunrise) with current generation batteries (Say Thunder Sky Li-ions) will perform better than a car with a hydrogen powered internal combustion engine. Course, you can always give your money to the oil companies to fill up your big hydrogen tank every 200 miles when your solar cells can't keep up.
Since he's using a fairly conventional internal combustion engine, no high temperature ceramic kit he's only getting around 30% of the energy from the hydrogen that he's put in to elextrolyse the water.
It's lost to the efficiency of the cells which are usually only about 15%-18% and it's lost to the angle of incidence of the energy from the sun, unless your panel is at 90 to the sun's rays you'll only get sin(Ø) of the rated output.
Sexuality appears to be as much to do with the parenting environment as genetic or environment within the womb where both twins are subjected to the same genes and environment. It's a common misconception that identical twins are brought up in an identical manner.
Where identical twins have been brought up under completely different conditions and one is gay, there is only a 50% correlation with the sexuality of the other twin. This suggests that the environment plays a significant role in the development of sexuality, though the genes or conditions within the womb also play a role.
The UK government have been using them to royally sqrew up projects for decades. The US government seem to prefer CSC for that, so I'm not sure who's the market leader in fucking up big IT projects at the moment.
Is the F650 FAQ. It is amazingly detailed, in fact it's grown beyond FAQ status. It describes pretty much every detail you'd need to know to perform mechanical work on a BMW F650 bike.

The problem with it is that it's basically Frontpaged into place and the maintainers are now buckling under the strain of keeping it up to date and looking for volunteers. Unfortunately they seem to be unwilling to investigate tools like those mentioned in the article which could take the load off and improve productivity.
As a consultant I've found that small businesses are by far the most likely to make use of free and open source software to try to keep their costs down, but the irony is that small businesses are the ones which benefit least from license, support savings, the difference is really fairly marginal for a small company with only a few employees.
I've also found it's better to roll out free software on their existing Windows systems before introducing them to Linux (usually as a mail/file/web server first).
There's a US government paper on it, the link's been posted to/. a number of times but I've forgotten it. You're right though, there are better crops to use for biomass. The Brazilians have been using sugarcane for decades, and the Hawaiian government have some good papers describing the relative merits of different crops.
In fact, the vehicle which could do it was developed 7 years ago. It was called the Solectria Sunrise. Composite construction, 4 seats and a trunk for bags, very low drag, and 400 miles per charge on NiMH batteries. Updated to use current battery technologies would just about double that range and with next generation li-s batteries the potential range would be around 1300 miles per charge.

Anyway, who wants to drive 1000 miles per day. Any more than about 400 is seriously painful.
It's fucking terrifying. I've only experienced it on my bike, on a track after a few laps of giving it some serious stick. Doing 110 miles per hour towards the end of the straight apply said brakes and sweet fuck all happened.
If you've been applying brakes, they heat up, they heat up the pads, the disks and the brake fluid. If it all gets too hot, it all just stops working.
You know how films rarely live up to a book?

It's pretty much the same the other way round for books based on a film or TV series. My take on it is that the arts don't often translate well across media.
The throttle sensor gets stuck on max, the gearbox is a sequential automatic with safety features to prevent damage to the engine, they take away the key and lock the card while driving and you get launched down the road at 120mph.
Yay Renault! Sounds like a lot of thought has been put into how to make a single point of failure *really* dangerous.
Sequential, slipping it into neutral might not be an option. I can't find out enough about it from the Renault web site to see if it can be dropped into neutral from any gear.

They are a global organisation, use a global filesystem, replicated servers. Hell, the software is even free, all they have to do is set it up:
OpenAFS or Coda.
As long as a single server survives your sites stay up.
Rather than RAID, they need something like AFS which would allow a bunch of servers to be knocked out but would still continue to function normally. Sprinkle them around half a dozen countries and taking out your organisation becomes extremely difficult, it just needs one to survive.

I've posted the link to the Solectria Sunrise several times. Look it up on Google.

But I think your conclusion is otherwise correct.
"Try and build a car that will go 200+ miles on a charge."
It's been done, a decade ago.
Your internal combustion engine is only 25% efficient, the gearbox, transmission and traffic/idling drop that efficiency to around 10-12%.

The fact that only 50% of the population bother to vote is a reflection of the lack of political representation.

Next... Low Earth Orbit, then I suppose Lunar orbit.
Cool...
