At the LHC, to understand all the particle physics processes they do a ton of calculations using quantum field theory. So I guess it can still be considered quantum physics. Since quantum field theory is based on quantum electrodynamics, which is based on many-body quantum mechanics, which is based on standard QM. QM…

You're talking to a nuclear physicist. There's a big difference between kW.h and kW/h. That's why I pointed out your mistake. I don't know the maximum discharge times of batteries since at some stage it is limited by chemical processes, but in terms of power transfer, yes it will be large. 20kw.h in 5mins is only…

Thanks for your post. But I am going to defend Ashley here. I wouldn't call the article "misinformation". You just elaborated with more details. I do recognize the prongs to be a standard 3-phase connector. Combining the DC into the same plug is a good idea though. Consumers don't want to learn the difference. They…

Neat. The key to this "dance" is that the piece of sodium isn't too large. It was too heavy such that the weight force was stronger than surface tension of water, then it would sink into the water and then the dude/dudette would have sharps of glass in his/her eye. :D

hahaha love this comment! +1000 HP!

Sometimes smart tech guys don't follow technical/legal details. :-)

Thanks!

Where has Molly Oswaks disappeared off to? I miss her posts.

Do you mean 85kW.h?

Oh. Is Ashley Feinberg a new author at Gizmodo? Welcome and good luck!

Where did the 8 hours to 20mins charging time come from? I didn't know the time was restricted by the plug shape/connections.

Any process involving pressurizing (the 1st step for producing LN2) and then liquefying is very energy inefficient due to the 2nd law of thermodynamics. According to the ideal gas law one learns in physics class when we're 15-16 years old: PV=nRT, so if pressure goes up, so does temperature. And we supply this energy…

Negative. The price is set by supply and demand. Currently LN2 and LO2 are only used for very few applications. If LN2 becomes a pressure source for cars, demand will increase dramatically, so will its price. Especially when it is no longer a by-product.

The answer is "no". Energy used in the production not taken into account. Bad science. Q.E.D.

Magellan did. On an earlier trip to east india he made it further east past the point he died on his last trip via the land of vespucci.

Don't need no infographic. Just the word "balloon" is a give away. It was a floating balloon. To float a object needs to displace gas. Gas != space. QED.

Is this what you tell the ladies? "2" is close enough to 6"! Let's not split hairs about this! It might not be technically exact. Don't cheapen it!"

Your human blood will boil if exposed to pressure above Armstrong limit? Not if you have more steroids then red blood cells in your veins! SNAP!

That's a lot of +s. I'd say +1.2 jillion would suffice.

That's what I meant.
