Wind power isn't confined to massive turbines found in the
middle of cornfields; a Polish company has developed a
3D-printed, foldable wind turbine that can generate up to 300W
of clean electricity -- enough to power your smartphone. And
best of all? It fits in your backpack. We're also one step
closer to having phones that charge themselves -- Michigan State
researchers unveiled a crystal-clear solar panel that can be
integrated into smartphone displays, windows and other
transparent surfaces.  Portable renewable energy has real
benefits beyond fighting climate change. Case in point: A new
type of solar-powered mobile technology is being used in India
to help prevent prenatal deaths. The device can deliver health
information about patients in remote areas to doctors, alerting
them to possible pregnancy complications. In other green energy
news, NASA scientists have created a new type of solar array
that unfolds like an origami flower. A human mission to Mars is
still a few years off, but that isn't stopping
