Green Steel Homes
Made entirely of recycled, re-claimed steel, these kit homes are long lasting, termite and bug proof, water/mold resistant,
and enduring... and the variety and architectural beauty for a kit home is un-matched.

Concentrated Solar Power (CSP) Plant powers 6,000 homes in Seville, Spain
The researchers found that by rearranging the mirrors, or heliostats, in a pattern similar to the spirals on
the face of a sunflower, they could reduce the pattern’s “footprint” by 20 percent and increase its potential
energy generation. The sunflower-inspired pattern allows for a more compact layout, and minimizes heliostat
shading and blocking by neighboring mirrors. The researchers published their results in the journal Solar Energy,
and have recently filed for patent protection.
Source: New Type of Inverter Could Drive Down the Cost of Solar Power
The new inverter setup mentioned above involves equipping each solar panel with a small inverter, instead of connecting
all solar panels to one large inverter.
Typical solar setups suffer from lower efficiency because of the way the panels are connected, which is in series.
A series connection means that electricity flows from one panel, through the other, and then the next, until it reaches
the end of the circuit. When one panel is shaded, the power output of the rest of the panels is reduced because the
electrical resistance of the shaded panel restricts the flow of electric current to the rest of the panels.

Discovery Could Cheaply Provide Significant Solar Cell Efficiency Boost
According to a recent University of Texas (in Austin) press release, solar cells could soon extract twice as many
electrons from each photon of sunlight received. This would be achieved using an organic plastic semiconductor material --
doubling the current solar power efficiency from 15% to 31% for solar energy capture and conversion.
