NC State’s new efficient pico projector raises hopes for smartphone cinema

NC State's new efficient projector

A team at North Carolina State University has developed a new liquid crystal projector that could spell the end of bulky and noisy cinema gear. Conventional tech passes unpolarized light through a filter, but the process is so inefficient that nearly 50 percent of the energy is wasted just keeping things cool. Fortunately, the Wolfpack and ImagineOptix filter claims to be 90 percent efficient -- meaning that future projectors could be far sleeker. It's also a good sign for future smartphone pico projectors, although we're not sure how the owners of our local theater will feel when we start undercutting them with just a phone and a white wall.

Inhabitat’s Week in Green: solar supertrees, pee-powered plasma and a bug-eyed mantis shrimp with a serious right hook

Posted on by
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

DNP Inhabitat's Week in Green tktktk

It's been a big week for energy-efficient breakthroughs in the scientific community. Scientists at MIT developed a new type of textured nano surface that could reduce the thickness of silicon used in solar panels by more than 90 percent, bringing down the cost of photovoltaic technology. Meanwhile, in the land down under, researchers at the Australian National University are working on a pee-powered plasma thruster that could make deep space missions more feasible. Also this week, a team of engineers from MIT developed a new glucose fuel cell that runs on the same sugar that powers the human body and could be used for brain implants.
