Why can't all car manufacturers be like this?

For the last week or so, you couldn't open a newspaper or turn on a radio or TV news bulletin without growing increasingly concerned about fuel shortages. Thankfully in the South East generally, and Kent in particular we seem to have escaped the kind of fervour affecting other parts of the country.

But almost as certain as death and taxes is the fact that fuel prices are unlikely to fall; surely all the more reason why we should be exploring alternative technologies. Yet the hybrids, like the Toyota Prius or the LPG Ford Ka, whilst novel and perhaps a little more economical, still don't really make the kind of fundamental shift that's needed.

Until now. I see from the Dow Jones "Market Watch" blog site that the Japanese have developed a car which delivers 188 miles per gallon - of water.

Don't believe it? Watch the video here.

And then wonder why all car manufacturers can't be like this?
