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 »

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 »

Combining The 5 Best Solar Technologies

Monday, October 27th, 2008

I know there is a lot of red tape and patents that would make this impossible in the near future, but what if we could combine the 5 most effective solar technologies in the world and create a super solar collector that would be able to take care of our energy needs? I know it kinda sounds like Captain Planet, but I don’t think its too far out of reach. A few criteria have been taken into consideration. The super solar cell must be efficient, drive the cost down, and solve the problem of solar power at night. I know its a long shot, but here are my five picks.

1. In terms of the shape of the cell, I think Solyndra has it right in making cylindrical solar cells. They don’t have to be mounted at an angle. They can be mounted flat which saves installation costs and makes them more durable read more »

Hydrogen Storage Milestone

Tuesday, October 7th, 2008

Nanotechnology is at work once again. The US Department of Energy’s target of 45 grams per liter for hydrogen storage has almost been met using graphene sheets that are one atom thick connected by columns of carbon nanotubes. Hydrogen is stored in the gaps between the nanotubes and the graphene sheets. The researchers also added lithium ions to the structure for increased storage capacity.

While they haven’t built the ‘pillared graphene’ structure yet, the scientists’ calculations indicate that it could store up to 41 g of hydrogen per litre, just short of the DOE target of 45 g per litre.

“Our material is capable of hosting a large number of hydrogen molecules without the aid of external pressure,” says Froudakis. “Thus the material [should be] safer for usage on automobile applications and will provide faster loading times than any other existing material.” read more »

Solar Panel Works At Night

Monday, October 6th, 2008

Researchers at Idaho National Laboratory partnered with Microcontinuum Inc. and Patrick Pinhero of the University of Missouri, are developing a new way to collect solar energy using nanotechnology that could cost pennies a yard, be imprinted on flexible materials and still collect energy at night.

The technology uses a special manufacturing process to stamp tiny square spirals, or “nanoantennas”, of conduction metal onto a sheet of plastic and the team estimates individual nanoantennas can absorb close to 80 percent of the available energy in comparison to current read more »
