New Solar Panels Don’t Need Direct Sunlight

Friday, September 18th, 2009

GreenSun Solar Panels

In North America, one of the problems in harnessing solar energy is the fact that there needs to be a slightly south facing roof in direct sunlight for the solar panels to produce an optimum amount of energy.  This might no longer be the case. read more »

Better Than CFL, Better Than LED…ESL

Friday, September 18th, 2009

esl bulbOver the past few years, the light bulb market has become more and more competitive as consumers want to spend less and less on electricity as the price per kilowatt hour rises.  I wish it were a more altruistic reason, but I digress.

CFL’s are the cheap alternative, and I don’t mean Canadian Football League.  They are relatively inexpensive, and have a good bulb lifespan at between 6,000 to 15,000 hours.  However, it produces a poor light quality, takes time to warm up, and is not fully dimmable, but the real detractor is that it contains mercury.

LED’s are thought to be the future of bulbs.  They have a longer bulb life at between 25,000 -100,000 hours, read more »

Nanotech Film Could Boost Solar Efficiency

Thursday, September 17th, 2009

nanostructure filmChemical Engineers at Oregon State University have come up w/ a way to deposit a “nanostructure film” on a multitude of surfaces.  The film will essentially make solar cells less reflective and able to absorb more photons for conversion of light to energy.  This new technology will enable solar cells to perform better at a lower price.  What makes this technology even more convenient is that it can be applied on site in a dispenser’s office.  No special manufacturing process is needed. read more »

Boston Bike Sharing

Monday, August 17th, 2009

bixi-bikeBikes are great ways to get around, especially if you live in the city and go no more than a few miles to get to work or to get groceries.  They are more nimble and can get in and out of traffic much faster than cars or other forms of public transportation.  The only problem with bikes is that they are a pain to store, and where are you going to put that in a 600 square foot efficiency?

The Metropolitan Area Planning Council of Boston understood the plight of its citizens and started working on a project that would allow Bostonians to borrow bikes for short trips as early as next summer.

The Public Bike System Company, a Canadian company will start implementing the bike share stations in Boston and will eventually extend the program further into Cambridge, Brookline, and Somerville.

A similar program has already been implemented in Montreal and has had glowing reviews.  Riders will simply  scan a credit card before they take a bike.  No more waiting for buses or taxis, and more importantly, no more pollution.

10 Ways to Save Water Today

Monday, August 17th, 2009

water_drop1As we all know drinking water is a precious thing.  Its such a shame that so much of it goes down the drain without it even entering our body.  I am pretty sure that I am conscious of it because my parents strived for an efficient lifestyle (turn off the lights if you are not in the room…turn off the tv if you are not watching it…etc…)  So here are some tips to save water starting today.

1.  Many people leave the water running when doing the dishes.  This is not necessary.  This is how I do the dishes.  I turn the water on about 1/4 to 1/3 of full blast.  During this time, I scour the dining ware.  Then I wash a small sized read more »

Increased Solar Yields By Two to Three Times

Tuesday, September 30th, 2008

Vinod Kohsla, the founder of Sun Microsystems, who is now an alternative-energy venture capitalist, has discovered a new technology that will increase solar yield by 2-3 times what it is today. In an industry that lauds even the most incremental gain, this is a huge leap towards mainstream solar energy.

The new technology really isn’t new at all its simply using the heat behind solar panels and harnessing it for additional energy. This technology not only provides an additional heating source for a hot water heater or heating in the winter, it also helps the solar panels to cool. The hot air is moved by a small fan that pumps it to wherever the heat is needed and additionally adds more efficiency to the solar panels by cooling them down.

“We make around 100 percent more energy than a regular PV system,” said Gordon Handelsman, president of PVT Solar. Although no specifics numbers were given on specs or how many they have installed, they said have successfully installed between 10 and 20 units.
