The George R. Brown Convention Center

The George R. Brown Convention Center (GRB) Solar Pilot Program, managed by the Houston Advanced Research Center (HARC) is part of the Solar Houston Initiative (SHI), a Department of Energy (DOE) Solar America Cities (SAC) program. The DOE SAC program is a federal program to accelerate the adoption of solar energy technologies for a cleaner, more secure energy future. Sponsorship and funding for the GRB Solar Pilot Program was provided by the City of Houston, GRB, HARC, Houston Endowment Inc., Standard Renewable Energy (SRE), The American Institute of Architects, Houston Architecture Foundation, BP and CenterPoint Energy.

The system consists of  51.3 kW DC STC crystalline module array  and a 49.0 kW DC STC amorphous thin film array. The crystalline module array consists of 270 BP modules, rated at 190 watt (W) DC STC, located on the I-beam along the south side of the building, mounted on supports painted to match the color of the existing beams. The amorphous silicon (a-Si) thin film array consists of 360 Uni-Solar Photovoltaic (PV) flexible thin film panels, rated at 136 W DC STC, installed on the southern portion of the GRB roof adhered with Green Lock membrane adhesive. Each array is connected to a Satcon Photovoltaic PowerGate Plus 50 kW 480V 3ph 60Hz Nema 3R inverter system (Model # PVS-50-4UL-10 Years). The inverters are connected to the building’s electrical distribution system.

Spinach could lead to alternative energy more powerful than Popeye
Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.<img src="http://feeds.feedburner.com/~r/sciencedaily/matter_energy/solar_energy/~4/ZPOt4C7LmqY" height="1" width="1"/>
