Comment Re:by putting back doors in (Score 1) 98

There are two fatal flaws in your reasoning:
1. You assume that "the police" and "the criminals" are disjoint sets.

He does no such thing. He is suggesting that, say, Apple would hold a key and would only unlock a device in response to the concurrence of two separate branches of government. In this case the executive and judicial.

2. You assume that innocent people have nothing to hide, and nothing to fear from the police.

He made no such assumption.

Yeah, if he was spilling his guts to Russia, you could hardly blame the guy since they are keeping him alive. If the US had any vestigial brains left they would give Snowden a pardon, even if only to shut him up.

No, I could and would definitely blame the guy. It wasn't an accident that he would up in that position. It took quite a bit of effort on his part.

In the end he'll probably be traded back to the U.S. for some trivial concession.

Comment Re:Hydogen is just a way to store energy (Score 1) 630

You're absolutely right. Fuel cells are just an alternative (or more likely an augmentation) to batteries.

Batteries are efficient in terms of storing electricity, but are very heavy to lug around even when almost 'empty'. They also take a relatively long time to take on a full charge.

Fuel cells solve both of these problems, but are currently more expensive to fill. Cost to manufacture is in flux for both.

Don't be fooled by overall efficiency arguments. It's only about cost and convenience. Both of these technologies are just beginning to challenge internal combustion engines - which are notoriously inefficient, but cheap and convenient to run.

I see this being mentioned over and over again - Hydrogen is nearly impossible to contain. Yet Germany managed to do it in f'ing dirigibles in the 1930's. Yes, it ended with the Hindenburg disaster, but they had made several transatlantic flights, containing the hydrogen with 1930's technology balloons, before one ruptured for reasons still argued about. But you know what? Most of the people aboard the Hindenburg survived.

Today, hydrogen is shipped all over the world. The hydrogen tanks in the Toyota, Honda, and Hyundai FCVs are not science fiction. They're in production.
