Here's the MIT news article. This particular device uses solar energy to split water and store hydrogen. I recently attended a talk by Prof. James Barber of the Imperial College, London where he described his own work on understanding photosynthesis and described Dan Nocera's work as well. The photosynthetic machinery relies on a fantastically engineered molecular design which we would need to replicate using some heavy studies into single-molecular electron transfer in inorganic compounds. Time to hit the inorganic chemistry books, I say.

This TED talk is by the illustrious Cynthia Kenyon, where she describes experiments done by her which could reveal genes which cause aging, at least those that appear to do so in C.Elegans, everyone's favorite model organism.
An interesting debate should ensue about what the implications of such research could be on the human race, given that part of the population problem, and indeed most current global problems, is due to an increased lifespan in humans.

Electric + aircraft = good news for hippies and corporates.
This one was the result of a competition which was held, but that doesnt stop people from starting up interesting stuff with it.

No time to comment further from my side. I hope we see these in the market soon, presumably they should be quite cheap, assuming they're made of polymers.

This article reveals new materials which hold promise of being good enough to store solar energy indefinitely, and rather than as heat (which has till now been the most efficient way of storing solar energy), they store it chemically. very exciting!
It's energy lying around for anyone to use, and this guy had long ago come up with a way to make a miniscule amount of energy from heat.
However, as usual with any technology that hasn't made it to the bigtime, its too expensive and produces too crappy an amount of anything.
However, thermoelectrics are making a comeback with polymers. That's plastics, which have the potential to convert heat differentials into electricity.

I’m not meaning to be nationalistic with this post, but since I am Swedish I also have a special eye for Swedish innovations. During last year at my home university I heard about a project called Down to Earth. The project aims for technology transfer from you know what!? Space!!
Sustainable and energy conservative solutions have been a necessity on space shuttles since before Neil Armstrong said “One small step for man...blah ”. So why not apply these solutions in our everyday life? I am really looking forward to see what comes out of this project. And just imagine what other sources of inspiration lies in wait for exploitation? Can we find it in a remote African tribe? In your grandparents kitchen? In a children’s story?
Who knows, it could very well be ... a big step for mankind!

A vehicle that can move in the sky for ~3 weeks uninterrupted, doesn't need an airstrip to land, and has numerous other advantages.
It looks a bit like a zeppelin, which just makes it fifty times cooler.
I am anxious to know when these would hit the market.

The article says it all, I'm gonna go read the actual publication now, which is here.
google it and you shall find how much people's nuts are being driven with this. I haven't felt this excited since I heard what Craig Venter's lab had done.
Of course, one should keep in mind that these guys are trying to treat dementia, but I am interested in the memory-expansion applications, where one could upload memory into someone's brain. Perhaps even store it chemically, electronically. I think I need to get a few more degrees.

Well, after a bit of snooping around, this man has already tried this. But there's no mention of the efficiency etc. Of course, since he thought of it first, he's already give it his name.
Of course, it's a little more complicated than just applying a heat difference between two pieces of metal. And it's actually very interesting, with theoretical efficiencies being as high as 60%. It's still going on, hope we can get more updates soon.

These fluorescent films use total internal reflection of fluorescent light within these films to concentrate it, which can be fed to solar cells.
The coolest part is that even diffuse light (cloudy days) can be concentrated using these. That's the part that really got me really get aroused.

This power plant uses the principal of osmotic pressure where fresh water meets salt water.
These guys at Max Planck Mainz (incidentally my favorite max planck institute) have come up with a way to up-convert the IR-region photons of the solar spectrum to UV-vis range ones, thus using the entire spectrum.
I think spectrum conversion is the obvious next step that materials scientists and chemists need to explore. more soon.

This TED talk speaks of forecasting technologies, and the standard trends they seem to follow.
I think this is an excellent way to get some perspective, figure out where to head, and as a general case study of previous technologies.
'Nothing lasts forever, and we both know hearts can change.' - GnR, November Rain.
This site presents some facts and figures about why we'll be seeing solar energy everywhere soon. bottomline: coal is going out (even though its cheap) and solar is on its way in. More posts about R&D coming soon.
Hopefully this excited you as much as it did me.
The most interesting part of this approach is the use of the large IR portion of the solar spectrum, which means it is independant of cloudy days. (more research needed into this.)
This is more a review of technologies-to-be that shall change our lives, and less a review of the latest gadgets available in the market for consumer production. There are several other sites for this.
