Our deep freeze is located in our semi-attached unheated garage. Never placed there because of energy reasons (didn't want to haul it to the basement), in the cold of winter it seldom turns on and in the summer it uses less energy because it's in a cooler place to begin with.

An interesting new technology for the fabrication of solar cells...

BBC News - Solar cells made through oil-and-water 'self-assembly'



Quote:
the team borrowed an idea familiar to fans of vinaigrette: they built their two-dimensional sheets at the border between oil and water.
They first built a device blank as before, with depressions lined with low-temperature solder, designed for individual solar cell elements.
They then prepared the elements - each a silicon and gold stack a few tens of millionths of a metre across - and put different coatings on each side.
On the silicon side, they put a hydrophobic molecule, one that has a strong tendency to evade contact with water. On the gold side, they put a hydrophilic molecule, which has the converse tendency to seek out water.
By getting the densities of the oil- and water-based parts of the experiment just right, a "sheet" of the elements could be made to "float" between the two, pointing in the right direction thanks to their coatings.
The conveyor belt process is to simply dunk the device blank through the boundary and draw it back slowly; the sheet of elements rides up along behind it, each one popping neatly into place as the solder attracts its gold contact.
The team made a working device comprising 64,000 elements in just three minutes.

Solar Shingles See the Light of Day

Quote:
In October 2009, the chemical giant unveiled its product, which can be nailed to a roof like ordinary shingles by roofers without the help of specially trained solar installers or electricians. The solar shingles will cost 30 to 40 percent less than other solar-embedded building materials and 10 percent less than the combined costs of conventional roofing materials and rack-mounted solar panels, according to company officials.

A start, although price point needs to drop a bit further. Big stumbling block here is the inability to sell back to the power utility + the exorbitant gouge fees that further inflate the power bill. The only way to really benefit is going completely off grid which then means a large bank of batteries which also have to be purchased and maintained.

Ontario signs green energy deal with Samsung team



Quote:
Ontario has signed a multibillion-dollar deal with a South Korean consortium, which includes Samsung, to develop green energy in the province.

The group, which also includes the Korea Electric Power Corp., will set up production facilities to manufacture wind turbines and other renewable energy equipment, and it will also develop large swaths of wind and solar farms.

The consortium's investment in the project - which promoters say is the largest of its kind in the world - is estimated at between $5-billion and $7-billion.

CM, what do you think about charges from some people that wind farms are not the way to go?

FeXL, depends on the criticism / problem. I know some people claim there is noise, or feel vibrations, or kill birds, etc., but I see that as just an issue of engineering and design.

For example:
New wind turbine design could triple power

New wind turbine design overcomes drawbacks

and then this innovative design...

+ YouTube Video

Wind power anywhere with MARS
