Inhabitat's Week in Green: shifting towers, hydrogen beads, and the shockwave engine for fuel efficiency

Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

It was a big week for alternative energy as Inhabitat showcased a range of green fuel innovations that cut costs while bringing clean energy to the forefront. We looked at hydrogen 'Micro Beads' that could fuel cars for $1.50 per gallon, and we saw Michigan State University unveil a new shock wave engine that could triple fuel the efficiency of hybrid vehicles. XL Hybrids also got in on the action by releasing an add-on kit that can transform any gas-guzzler into a hybrid, and Google made waves by announcing their investment in biofuels startup CoolPlanetBiofuels and adding EV charging stations to Google Maps. Finally, to round out or green automotive news this week we also have to give a special shout out to Artega, who introduced their hot new SE Electric Sports Car - we can already hear the honks and catcalls!

Off the road and out into the ocean, we showcased a design for underwater kite turbines that harvest energy from ocean waves, and we were wowed by Kinetura's shape-shifting Kinetower. In other architecture news, construction finally commenced on MVRDV's massive Amanora Vertical City Apartments in Pune, India -- a mixed use development totaling over 4.3 million square feet.

We also saw several new developments on the solar power front - scientists in the United Kingdom are working on a solar-powered kit that could lighten the load of soldiers-and, more important, increase their mobility-by up to 50 percent. That seems like the perfect complement to OS' amazing GSR 110B - a retractable solar power system that delivers 40 watts on the spot with a combined solar and battery backup. Lightweight and easy to pack, the solar unit is easily deployed in emergency situations as long as the weather permits.
