Top 10 green tech stories of 2009 | A recent article in Discovery News has outlined the top ten green technology stories of the year 2009. At number
one is automotive researchers looking towards nature for inspiration to build
car parts, like coconuts, wheat waste and even root vegetables. At number two
is the report of solar cells becoming cheaper than before, with Australians breaking
record with their solar cell production, DIY panels hitting store shelves and
the massive Desertec project moving forward. Desertec is a concept for making
use of solar energy and wind energy in the deserts in North Africa and Middle
East proposed by the Desertec Foundation. At number three is the launch of the
first legal "flying car", developed by Terrafugia. Known as the transition plane,
it is a street-legal plane that gets great fuel efficiency, requires a pilot's
license, and could mean less congestion in the skies. At number four is the official
launch of the DustCart robot, which has potential to make recycling collection
quieter and smarter. At number five is the story of scientists discovering a special
mineral in shark teeth called apatite, which could help us determine what ocean
temperatures used to be like long ago. At number six is researchers focusing on
developing the bike as an eco-friendly tool. For example, a group at MIT made
a laundry bike and a group of students from New Jersey fashioned an agribike thresher
for sorghum and millet. At number seven is the story of nanotechnology demonstrating
its "green" potential. A superhydrophobic surface crafted by Duke University scientists
with carbon nanotubes could shrink power plants, AggraLight nanoparticles promise
to lighten up solar cells while improving efficiency, and a nanostructure in algae
led to lightweight, flexible batteries. At number eight is the story of geoengineering
becoming real with the University of East Anglia doing a scientific evaluation
of the most massive Earth-scale engineering plans out there and the Oxford Geoengineering
Institute launching in the fall. At number nine is scientists using manure to
generate electricity in a big way. The city of Oslo in Norway made plans to turn
municipal sewage into methane for a new city bus fleet, an aid group in Haiti
called SOIL set up dry composting toilets to make humanure, and a sterling engine
powered by cow dung was tested. At number ten is the development of smart grid
devices in 2009. GE (General Electric) announced that it will start making smart
appliances, Google made a smart meter application, and a bunch of competitors
collaborated to secure smart grid devices. |
