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It’s an obvious truism, but one that may soon be outdated: The problem with solar power is that sometimes the sun doesn’t shine.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

I have thought a lot about the vocabulary we use when we speak about issues. Much of the language we use comes to us courtesy of Economists. We speak of consumers or clients rather than citizens. We speak of economic debt and deficit to the exclusion of the discussion of social, cultural, environmental or infrastructure debt and deficits. We speak of healthy economies rather than healthy people, or healthy environments. And we rarely ever focus on important issues like fun or happiness.
This vocabulary poses a number of real problems for us. One very real problem is that if we use economic terms to describe our problems, the solutions we find will be limited to those that offer economic value. This is the old problem where having only a hammer in your tool belt tends to make every problem look like a nail. In the long-term, if we are to really deal with important issues in a constructive way, we have to change the way we speak to reflect our real values. This type of culture change takes time, and, if science is to be believed, we don’t have a lot of time before the chaos starts.
In the meantime, we can at least frame our economic arguments in terms that demonstrate that sustainability is at the heart of long-term economic success, and that is done brilliantly in a TED talk (embedded below) by Chris McKnett from 2013.
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).
When we bought our new house about 4 years ago, we wanted to be able to take some control over the utility costs so that when energy prices rise, we would have a bit of protection. There are lots of technologies out there that are environmentally friendly, but not all of them are suited to use in a sub-division and many have a low rate of return on investment. 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!
