From NOVA PBS, Solar Power:
The amount of solar energy that strike the surface of the Earth in one hour is more than enough to supply every person on the planet with electricity for an entire year. However, there are limits that prevent us from being able to fully take advantage of this energy.
For now, at least!

Footage Note: The slower video represents a closer resemblance to the true speed of the International Space Station; this footage was shot at one frame per second. Clips are all marked with an *.
There are more International Space Station videos in the archives, including a tour of ISS and what is perhaps our favorite time-lapse view: Further Up Yonder: A Message From ISS To All Humankind.
Powered by wind turbines, solar panels, and a biodiesel generator, the NY Sunworks Science Barge (now in Yonkers, New York) is a model for energy-efficient, sustainable urban farming. Using a hydroponic system that requires no dirt, the floating greenhouse uses less water and space than traditional farming in fields. And their state-of-the-art computer technology creates an optimized environment for nourishing tomatoes, cucumbers, strawberries, basil, lettuce and more, “with zero net carbon emissions, zero chemical pesticides, and zero runoff.”
It’s not only a great educational field trip for school kids from all over the region, but continues to be an example of how growing local food in cities can be fresh, healthy, and sustainable, all while cutting down on transportation costs and fuel needs. From NYTimes.com:
“It’s a living science lab that on its first level is a demonstration of how we can grow food with fewer resources and that we can produce what we need without damaging the world around us.”
If you want to make your own hydroponic plant-growing experiments, there are kits for kids here and here. Or Instructables has written out steps for making your own hydroponic system using stuff around the house.
If you’re in the New York area, visit the Science Barge!
This video might seem like déjà vu — you’ve seen something like it before — but this one is so much more stunning! Be sure to watch it HD full screen.
This new (or newly edited?) video was shot with a special low-light 4K-camera by the crew of expeditions 28 and 29 onboard the ISS from August to October, 2011 and captures numerous shots of the Aurora Borealis.
