New green energy course inspires high school seniors from across the country

I always look at MIT’s stuff whenever the world gets me down and I feel like giving up.  There is so much innovation and enthusiasm there that my hope gets restored.  Thanks MIT!

New green energy course inspires high school seniors from across the country.

A molecular approach to solar power (MIT News)

This is another example of excellent innovation from MIT and Harvard. This one is for energy storage and it is quite similar to one I just recently posted on the “bionic leaf”. With better solar energy conversion and more efficient energy storage the idea of moving away from fossil fuels and nuclear power begins to look possible.

A molecular approach to solar power
Switchable material could harness the power of the sun — even when it’s not shining.

It’s an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn’t shine.

Now a team at MIT and Harvard University has come up with an ingenious workaround — a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand.

This solution is no solar-energy panacea: While it could produce electricity, it would be inefficient at doing so. But for applications where heat is the desired output — whether for heating buildings, cooking, or powering heat-based industrial processes — this could…

Solar light bulbs for pennies (Isang Litrong Liwanag/a litre of light)

A litre of light

I just ran across a wonderful innovationthat seems to have been around for a few years but just now seems to be garnering widespread attention. The innovation seems to be the brainchild either the Massachusetts Institute of Technology or of Mr. Illac Diaz of the Philippines. It is as brilliant in its simplicity as it is as a light bulb. I am going to leave the description of the “bulbs” and how they are used to the foundation (and to two interesting YouTube videos (describing the why and how). One of the linked videos below describes this as an idea out of MIT and that makes sense because that institution seems to focus on a lot of simple projects to help the poor (see my earlier blog about solar powered water desalinators that were developed by MIT folks).
