Comment "Explorations" had a good interview on this (Score 1) 581

On an episode of "Explorations" about a year ago Michio Kaku had an interview with David Goodstein of Caltech. Unfortunately the archive was deleted but it was on May 27, 2008. Prof. Goodstein claimed that if we were to switch to all Nuclear power for our electricity needs, we would run out of Uranium in 20 years.

Comment Re:ok, so now what (Score 2, Interesting) 64

If we're going to have graphene consumer electronics though, it's going to be based on the wafer-scale CVD manufacturing process developed in Korea and MIT.

Trust me, CVD synthesis of graphene is in the earliest of early stages. The problem is that neither group (Korea nor MIT) have figured out how to get the graphene off the nickel layer that catalyzes the reaction. There are other ways of making graphene that are much further along, such as epitaxial growth on silicon carbide.

Comment I prefer computer labs for work (Score 1) 571

This is unfortunate. The two universities that I am very familiar with both have very large computer labs where people can print out things. I am wholly reliant upon the university currently to print things out. I HATE toting around my laptop and so I prefer to use campus resources. That said, my department made the switch from physical computers to remote desktops. It's worked out well, but I have to say I don't like not being able to pop in and check my e-mail between classes without having to lug my laptop around like a ball and chain.

That's actually pretty cool. By concentrating the light, they need less photovoltaic material per square foot of land used for solar. I'm curious how the efficiency of photovoltaic cells varies with the concentration of light

For a constant temperature, efficiency goes up logarithmically with light concentration. A solar cell with 1 sun on it is going to be less efficient than one with 500 suns on it assuming you have a way to cool the cells. Past a certain point the efficiency drops like a rock due to lack of cooling the cells and this reduces the voltage you can produce by about 2.3mV/C past room temp.

Comment Facebook has had an evil ToS for awhile (Score 1) 409

I regret ever putting any information about myself on that website. Even though I deleted some of my old stuff (like e-mail), Facebook still holds the data hostage. Anyway, I found this funny:

and a new Facebook group called 'People Against the new Terms of Service' that has added more than 10,000 members today."

God that is the laziest form of protest ever. Yeah let's join a group on the service we are protesting to show how much we disagree with this new policy! If you take such exception, stop using the damned service.
