Comment Re:As they should be. (Score 1) 628

I ascribe to this principle as well but there's another side to the equation: don't do the crime if you can't do the time. In other words, I am all in favor of people leaking classified information but I am also in favor of them being prosecuted for doing so. Similarly, while I find torture abhorrent, if someone takes it upon themselves to torture another and should the data extracted be valuable (even preventing something terrible from happening), then the torturer should still be prosecuted for the crime.

Comment How to make a watercraft do the same thing (Score 1) 393

I think a DDW watercraft could be made to do this as well. Have two propellers: one in the air and the other in the water. Mechanically link the water propeller to the wind propeller. Assuming friction with the water isn't too great (flat bottom boat?) and the ratio between the water prop and the air prop is tuned, you should be able to make a DDW watercraft move faster than the wind.

Improved High-Performance Energy Storage 129

Physicists at the University of North Carolina have developed new improvements for high-energy-density capacitors that can store up to seven times as much energy per unity volume as common capacitors. "The amount of energy that a capacitor can store depends on the insulating material in between the metal surfaces, called a dielectric. A polymer called PVDF has interested physicists as a possible high-performance dielectric. It exists in two forms, polarized or unpolarized. In either case, its structure is mostly frozen-in and changes only slightly when a capacitor is charged up. Mixing a second polymer called CTFE with PVDF results in a material with regions that can change their structure, enabling it to store and release unprecedented amounts of energy."
