Of course the big question is how efficient is the process? Is it more efficient than just using the electricity to charge up batteries in an electric car for example?

TFA says 70%, then you get about 30% out of the engine, so the answer is no, but it trades that off against faster refuelling, longer range, and ability to use existing infrastructure rather than starting from scratch.

Which leads to an obvious question: Isn't the U.S. capable of producing its own anesthetics? At least the ones used for executions which should no longer be covered by patents?

Sure they could, but there's basically no market for it.

The established European companies have the legitimate-medical-uses market sown up, so that just leaves the killing-people market, which is really damn small, so they'd never even make back their investment, much less make a profit on it.

It would be possible to whomp up a government-owned corporation or government division to do it and not care about the cost, but the free market mania that the Republicans running the states that still do executions subscribe to probably wouldn't allow that or even have it occur to them.

How come proven liars such as Pelosi and Feinstein keep on getting re-elected despite all the goddamn things that they have done?

Because the alternatives presented by the other party are even worse, and due to the way the system was set up, both originally and by the changes made via the 17th amendment (which made senators elected, rather than appointed by the state legislatures), it's all but impossible for anyone not of the current major parties to get in (it's difficult enough for them to even get on the ballot).

Voluntary birth control is only a temporary fix. I still see plenty of big families.

All those big families don't make up for the childless and one-child families. It's simply statistical reality.

Even with those large families, the USA is slightly below the replacement rate. According to the CIA World Factbook, The USA is sitting at about 2.01 births per woman. You need about 2.1 to keep the population constant. The only thing that is keeping population growth going is immigration.

And the almost all (France is an exception at 2.08) rest of the developed world is way the hell below that. Canada is sitting at 1.59 and the EU collectively is at 1.55. China is also sitting at 1.55, and Russia is at 1.61.

Innocent people are inconvenienced and harassed all the time by unreliable evidence and eye witness testimony. Some are even convicted. The false positive rate for familial DNA is way down in the noise level. Why not point your outrage at the harassment of blacks on the streets of every major city.

Because unlike you, we have sufficient neural capacity to walk and chew gum at the same time and thus are also able to criticize police for multiple lousy practises at once.

Comment Re:512 should still be too high a bar... (Score 2) 89

512 bits isn't a very high a bar anymore.

It took 6 months and 8000 MIPS-years to factor RSA-155 back in 1999.

According to Dhrystone, the CPU in the computer I'm typing this post on could do those 8000 MIPS-years in roughly 3 weeks and you could probably knock that down to less than a day if you brought the GPU into the matter, let alone something with some real oomph.
