After a ball or compact rounded shape, the cube is the worst shape for passive cooling efficiency.

Also the shape must have been chosen only for aesthetic and not with any pratical considerations: this is not what I call design.

I'll check later for novel advice here, I surely missed the best ones he wrote.

France might help also. Areva has a lot of experience with nuclear reactors and wastes. They were willing to help during the meltdown, but at this moment Tepco seemed too proud to accept any help from the foreign countries.
They accepted later, as they bought some water filtering equipment to capture radionucleids.

Next time such a disaster occurs, I hope that the host country will not wait to aks help from the most competent companies in the world.

Am I alone on /. to be surprised that comment is "5 Insightful" ?

I've seen a scientific documentary that shows how crows can learn just by looking at other fellows and imitate them to solve practical problems.

Human, apes and dogs are hardly the only species to do so.

Maybe you are talking about Psygnosis - the company, but I am talking about Psygnosis - the band

Thanks for the refs, I forgot that...

So... do you also know why did they not carry on with this model ?

Some music groups have switched to Pay What You Want for a digital copy (mp3 download) of their album.
I bet they will have much more money than with any other distribution model.

For example, Psygnosis band started with this model, along with other merch and bonuses for those who want extra.

Even if I'm not a big fan, I paid a whooping 8€ for their album, digital copy, because I was happy to have it DRM free, and to be trusted by the band which feels confident that their listeners will pay a fair price.

All this money goes to the band, this is at least three times what they could get with physical sales.

The first thing the theft will do: an offline OS installation.

I bet the stolen Linux laptop will have its OS erased to either to run MS Windows or an other Linux distro.

Note: block change tracking is used to reduce reads in case of incremental backup. It is not required to allow incremental backup.

What would be your reaction facing the same harassment ?

- Do as if he does not exist, or as if he were transparent.
- Film him with a phone camera, but for how long ?
- Run away, faster than him.
- Freeze, but for how long ?
- Make a fake call, calling for an imaginary team of tough guys to get him and beat him bad.
- Start talking a lot, as if it were an interview, a VIP interview for something big, and answer imaginary questions.
- Hold a mirror, big enough, toward the camera.
- Do the same thing as Cowboy Neal.

XKCD has great ideas and methodology. Also finds out that...

Check out some funny paradox at 2032 and 2044 :)

Maybe we should google bomb the empty years and ask XKCD for a refresh!

I understand what you mean and you are not completely wrong. I know that the wind doesn't turn the propeller, the wheels are. This isn't an harvest as usual with a turbine.

The point is that the energy comes from the wind, or air momentum. A mass of air is stoped, or at least slowed down, and the energy gathered is transfered to the cart.
The only thing that can interfere (significatively) with the wind is the propeler. So it is not wrong at all to say that with the propeller the cart has gathered wind energy.

Again this doesn't mean it works like a turbine. It doesn't. That is why this mecanism is not easily understood.

I would like to thank the original poster, this is one of the best story I've read for weeks. I should have known this earlier but I didn't... Thanks again for pointing out this enlightening discovery.

First I really doubt it was real, then I wondered how it could be possible, now I understand how it works !

My short explaination: the propeller harvests the wind energy (relative to ground) that was in front of the vehicle. The more it moves forward, the more it stops different masses of air, accumulating wind's forward momentum.
