Alternative Energy-Solar Energy - Precisely what are Solar Balloons?
This past year an original concept in sustainable energy won the "Forward Thinking" award from the RE:VOLT Electrifying Ideas competition. That which was this new idea? Solar balloons produced by Israeli scientists Joseph Cory and Dr. Pini Gurfil for Sun Hope.
What are Solar Balloons?
Historically the phrase "solar balloon" has described simple black balloons that were filled up with air. Based on Wikipedia, "as sunlight shines around the balloon, air inside is heated and expands, causing an upward buoyancy force, comparable to an artificially-heated heat balloon. Some solar balloons are big enough for human flight, but usage is restricted to the toy market as the surface-area to payload-weight ratio is rather high."

As technology evolves, terminology evolves too. Now the title of "solar balloon" also can talk about a balloon like "platform" that contains embedded photovoltaic arrays or solar arrays so that you can convert solar technology into electrical power. In the case of the Joseph Cory and Dr. Pini Gurfil's Sun Hope design we percieve a lighter-than-air helium filled fabric balloon because platform or base. Each fabric balloon is stuck just using the bottom with two cables Body for helium refills, one other for passing generated electricity with a cp.
Sun Hope isn't alone of their pursuit of an affordable, functional solar balloon design. Another solar balloon design arises from Cool Earth Solar. Cool Earth Solar uses plastic balloons which might be suspended on wires. To acquire a visual, make a 2 meter wide mylar balloon. These plastic balloons also provide concentrated solar photovoltaics where light is magnified onto solar cells to maximize electricity generation output. A typical worry about solar balloons could be the ability to remain true in high wind environments, according to Cool Earth Solar, their system can withstand wind speeds as high as 100 miles-per-hour.
While solar balloons show promise like a photovoltaic implementation there are several concerns to get noted. These concerns however, are not any diverse from those found with medium to large wind power installations. Depending upon the size and style and of installation you can must consider things like air traffic regulations and potential bird collisions.
Solar balloons provide impressive value in isolated, off-grid locations along with temporary portable power supplies. In situations such as these, solar balloons supply a path to escaping a fossil fuel dependency.
Concentrating Solar Power
Both in of examples of solar balloons, the efficiency of the photovoltaic cells are improved by concentrating solar power (CSP). Based on the US United states doe, "concentrating solar power's relatively inexpensive and skill to offer power during times of peak demand - when and where we require it - imply that it's really a major reason behind the country's future needs for distributed options for energy."
Concentrating solar power system work by utilizing mirrors or another reflective surfaces to accentuate the force with the sun to a specific point. This power of energy can help the efficiency of electricity cells. As outlined by Cool Earth Solar, "multi-junction, high efficiency cells produced from satellite technology allow CPV systems to build exactly the same amount of electricity as traditional lcd PV systems while using around 500 times less solar cell material." With diminishing supplies of unprocessed trash required to manufacture pv cells, concentrating solar powered energy offers more energy with less garbage.
While today solar balloons are a new technology, soon they may be a strategy to curing our nation of it's reliance upon standard fuels. The Cool Earth team recently received $21 million that they can prefer to use to create a 10 megawatt plant utilizing their solar balloon technology. Because of forward thinking, environment friendly investors, a solar balloon based solar powered energy plant is often a reality over the following couple of years, someday it may well even power your own home.
