MIT Unveils First Solar Cells Printed On Paper 125

lucidkoan writes "MIT researchers recently unveiled the world's first thin-film solar cell printed on a sheet of paper. The panel was created using a process similar to that of an inkjet printer, producing semiconductor-coated paper imbued with carbon-based dyes that give the cells an efficiency of 1.5 to 2 percent. That's not incredibly efficient, but the convenience factor makes up for it. And in the future, researchers hope that the same process used in the paper solar cells could be used to print cells on metal foil or even plastic. If they're able to gear efficiencies up to scale, the development could revolutionize the production and installation of solar panels."

After Learning Java Syntax, What Next? 293

Niris writes "I'm currently taking a course called Advanced Java Programming, which is using the text book Absolute Java, 4th edition, by Walter Savitch. As I work at night as a security guard in the middle of nowhere, I've had enough time to read through the entire course part of the book, finish all eleven chapter quizzes, and do all of the assignments within a month, so all that's left is a group assignment that won't be ready until late April. I'm trying to figure out what else to read that's Java related aside from the usual 'This is how to create a tree. This is recursion. This is how to implement an interface and make an anonymous object,' and wanted to see what Slashdotters have to suggest. So far I'm looking at reading Beginning Algorithms, by Simon Harris and James Ross."

mrxak writes "It's official; Activision Blizzard's much-anticipated sequel to 12-year-old StarCraft is going to enter closed beta 'this month,' according to company President Mike Morhaime during an investor conference call. This comes in the wake of the SC2 beta forums showing up briefly on Battle.net. If you've got a Battle.net account, it's probably not too late to opt-in for upcoming Blizzard beta tests."

Great minds run in great circles.
