Wave-Powered Desalination 184

Posted by kdawson from the wanna-buy-a-duck dept.
dptalia writes, "Scientists think they've found a way to harness the energy of waves to desalinate salt water. Currently desalination is an energy-intensive process, but this new design harnesses the renewable energy of waves to produce fresh water. Many countries depend on desalinated water to support their populations, and this invention could lower the cost of water generation." Production versions of the "desalination ducks" would be about 10 meters in diameter and 20 meters long. Each would supply water for more than 20,000 people.

So do smart cards!

Thats the point of them, you cannot retrieve the secret key, as opening up the hardware on the card destroys it. Previously the only known way to brute force crack the key (in threory - there are other implementation specific exploits - remember ITV digital!) required very very expensive equipment and that doesn't work all the time. This is a revelation because now you can view the secret key for onlt 30 bucks.

But I quite like the look of these iButton things too.
