Doesn't this just turn your EV into a less-efficient gasoline-powered vehicle?

There's a common misconception that because an EV puts out no emissions, that it's 100% clean. And that because electric motors are 80%-90% efficient, EVs are 80%-90% efficient.

That number conveniently ignores the battery efficiency.

So lets re run those number including every thing.

Fuel to electricity 40% ( Generation plant)

Transmission ~90%

Battery Depends on chemistry

NI-MH ~66%

Li-ion ~80-90%

NiCd ~70-90%

SOFC ~60%

DC Motor 75-92%

Bottom Line From fuel to road

Best case 30%

Wost case with current EV batteries 18%

Modern ICE 20-25%

SOFC EV 45%

+ - Team Fortress 2: Free to play, forever->

Submitted by dotarray
dotarray (1747900) writes "If you think about it, it was slightly obvious. Steam started supporting free-to-play titles. Valve then confessed that it was working on one of its own. Valve also announced the “biggest, most ambitious update” in the game’s history.
and we still didn’t put the pieces together. We all assumed that the company was referring to an unreleased game, perhaps Dota 2. We slavered in anticipation of Meet the Medic. We were very pleased that Steam was broadening its horizons.
Until today, when the penny dropped: Team Fortress 2 is now free-to-play, supported only by microtransactions."

+ - France Bans Facebook And Twitter From Radio And TV

Submitted by Anonymous Coward
An anonymous reader writes "In France, radio and television news anchors are no longer allowed to say the words “Facebook” and “Twitter” on air, unless the terms are specifically part of a news story. The ban stems from a decree issued by the French government on March 27, 1992, which forbids the promotion of commercial enterprises on news programs."

+ - Is SHA-512 the way to go?

Submitted by crutchy
crutchy (1949900) writes "When I was setting up my secure website I got really paranoid about SSL encryption, so I created a certificate using OpenSLL for SHA-512 encryption. I don't know much about SHA (except bits that I can remember from Wikipedia), but I figure that if you're going to go to the trouble (or expense) of setting up SSL, you may as well go for the best you can get, right? Also, what would be the minimum level of encryption required for say online banking? I've read about how SHA-1 was "broken", but from what I can tell it still takes many hours. What is the practical risk to the real internet from this capability? Would a sort of rolling key be a possible next step, where each SSL-encrypted stream has its own private/public key pair generated on the fly, and things like passwords and bank account numbers were broken up and sent in multiple streams with different private/public key pairs? This would of course require more server grunt to generate these keys (or we could take a leaf from Google's book and just have separate server clusters designed solely for that job), but then if computing performance was a limiting factor, the threat to security of these hashes wouldn't be a problem in the first place. I guess with all security infrastructure, trust becomes a more important factor than technical abilities. Can I trust that my SSL provider hasn't been hacked (or at least snooped)? How do I know some disgruntled IT admin hasn't sold the private key of his company's root CA to the same organisation that developed the conficker virus? It would certainly make for a more profitable payload. I've read some of Bruce Schneier's work (I'm subscribed to Cryptogram) and he tends to highlight the FUD that surrounds internet security, and I agree that there is a lot of FUD, but complete ignorance and blase attitude toward security can also be taken advantage of. Where is the middle ground?"

+ - New giant offshore wind turbine with 80 m wing->

Submitted by jackd
jackd (64557) writes "Quite an interesting news piece on a new giant wind turbine being able to produce a whopping 7 MW, designed for rough sea conditions. Each new Vestas turbine will be able to provide electricity for 6,500 homes. The turbine has a greater capacity to generate electricity than any machine currently working at sea. Can't help but think this announcement is relevant in the face of the nuclear troubles, but how can they possibly cope with energy demand, or compete with one 1,000 MW nuclear plant."
