MIT Engineers Experimenting with “Solar Antennas”
Thinking hard about installing a solar system on your home or business building? While costs have often presented the biggest barrier to integrating solar energy into a building’s power mix, new financing and leasing programs have helped many overcome that hurdle. Roof space, however, still presents a challenge: unless you’ve got a big piece of land, rooftop panels are likely your only option for system placement… and the size of your rooftop will limit the number of solar panels you can install.
So far, few have gotten into the roof expansion business (which probably doesn’t make sense, anyway); a team of researchers at MIT (above left), however, have been digging into new technology that could help you make much more power in the space you do have. Chemical engineering professor Michael Strano and a group of his students have been experimenting with building solar energy “antennas” out of carbon nanotubes (hollow tubes of carbon atoms — above right) that would “concentrate solar energy 100 times more than a regular photovoltaic cell.” These tiny antennas consist “of a fibrous rope about 10 micrometers (millionths of a meter) long and four micrometers thick, containing about 30 million carbon nanotubes.”
In conjunction with a semiconductor, these nano-antennas could collect usable amounts of solar energy, and convert it into electricity, with very small space requirements. As Strano describes it, “Instead of having your whole roof be a photovoltaic cell, you could have little spots that were tiny photovoltaic cells, with antennas that would drive photons into them…”
While this technology is nowhere near commercial availability, it does create an innovative context for rethinking solar power production and efficiency. If you’re interested in the geekier details, check out the MIT News Office’s explanation of Strano and team’s “solar funnels“…

We at My Solar Power Information liked this post where the author differentiate between two distict types of solar energy systems. The post enlightens your thought when you think of solar power systems. "There is definitely a major difference between residential solar energy systems and passive solar energy systems but most people do not know what makes these two systems so different. The type of solar energy system that works for your situation will depend on what type of set up you have and where the system will be used at."
