Making investment practices more sustainable – Another great TED talk

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).

Further complicating matters is the fact that many of the municipal inspectors have no idea what they are looking at when presented with some of the new technologies. So which one to choose… Continue reading “Solar Hot Water – Not easy, but worth it!”
