Boston College and MIT collaborate to research improvements to the conversion efficiency of solar thermal panels. 

Nanotech materials and panel design techniques combine to boost the electric power conversion significantly.  …

…   “The team’s introduced two innovations: a better light-absorbing surface through enhanced nanostructured thermoelectric materials, which was then placed within an energy-trapping, vacuum-sealed flat panel.

Combined, both measures added enhanced electricity-generating capacity to solar-thermal power technology …”   …

Boston University’s Sean Elliott is researching a biochemical pathway to hydrogen fuel using bacteria-based red blood cells.  By combining light-sensitive pigments with hydrogen-producing proteins, bacteria could produce hydrogen through exposure to the sun.  …

…   “If they can make it work, the researchers hope to apply sunlight to induce chemical reactions in the pigments that will enable the microbes to produce hydrogen, an environmentally benign fuel. ”   …

Boston College researchers work on the nano scale to address the challenges of thin film solar cells and energy conversion efficiency.  The approach taken in this research on nanocoax cell architecture is to avoid the use of crystalline materials, which will result in lower-cost power with ultrathin solar films.  The team has achieved power conversion efficiency of over 8 percent, which is very encouraging.  …

…   “Physicists at Boston College found a way to resolve the thick & thin challenge through a nanoscale solar architecture based on the coaxial cable, a radio technology concept that dates back to the first trans-Atlantic communications lines laid in the mid 1800s. ”   …

Boston has a new take on trashcans. 

Their BIG GREEN compacting cans can hold up to 150 gallons requiring less frequent vists by sanitation workers ... and less mess as they do not tip over and spill!

"... solar-powered, self-compacting trash receptacles. ...need emptying only once or twice a day, ... ..."

"... powered by photoelectric panels, which supply power to motor-driven compactors inside. ..."

"... has placed 50  ... machines in neighborhoods and hopes to buy more as it gauges how much it can save in labor costs.
