Awesome, that is very helpful. > Then the _material_ is a store of energy. Once it's exhausted, the condensation will stop. The paper points out that the sample was surface that maintains a particular temperature (20 degrees C in th

It was definitely an interesting time. That said, the summer of '78 I was renting a room from an IBM engineer who had bought a Heathkit H-11 and was using it to trade stocks. They would enter the prices from the Wall Street Journal eve

Does hydroelectric power violate the second law of thermodynamics in your opinion? I mean 1. Drops fall from the sky 2. They collect and flow down a river 3. We use that river to generate hydroelectric power to get free energy! Water vapor,

Okay, I see where we diverge. The 'cube' was something I was thinking about not in the paper. I'll see if I can describe what I was thinking and you can tell me it breaks the rules :-). You coat a piece of aluminum with nano-

You didn't read the paper did you :-). First, it isn't a "condenser" (which is kind of the cool science here) it is more of a molecular sieve that exploits two materials (one that repels, and one that attracts) the molec

I think the work stands out anyway. Unlike adsorption techniques there is zero change to the mechanism which just keeps pulling water from the air. Presumably, they will put a layer of this material on aluminum to conduct the latent heat an

As a coding abstraction I really like this (not sure I'm completely understanding it, but it sounds handy.) I wonder if that's because I spent a couple of years doing kernel programming at Sun? Its nice to be able to write sleep(f

Nice work! I love an "impossible" problem that falls to bounding estimates like this one does. There was a surprisingly lot of work done in protein folding that had similar sorts of techniques to eliminate structures that would ei

This is pretty cool. I believe it was Bob Metcalf at PARC who had a device in his office that was hooked up to the 3Mbs Ethernet cable and would essentially do the same thing. He built and installed it to get a feel for how much of an issue
