Scientists figured out how to grow a material that could make solar panels cheaper. And a new jacket on Indiegogo captures heat from UV light then stores it in a steel mesh center to warm you up.

3D? Feh. MIT has already moved on to 4D printing (video)
The bad news: just as much of the world is starting to get excited about the prospects of 3D printing, science is moving on to the world of 4D. The good news: in the future, you might not have to assemble that Ikea chair yourself. "4D printing" is the term cientists are using to refer to a technology that MIT's Skylar Tibbits talked up during a recent TED appearance. The fourth "d" here is time, referring to an object that, once printed, is capable of changing shape (over time, naturally). "Essentially the printing is nothing new," Tibbits told the BBC. "It is about what happens after." So far the concept has been demonstrated with thin strands of plastic, which, once added to water, form into a predetermined shape, using energy from the absorption. Suggested future applications involve furniture, pipes, bikes and buildings. First, however, scientists will have to demonstrate the technology on a larger structure, of course, and they'll explore the possibility of other energy sources, like heat, sound and vibration.
