Alternative Energy-Solar Energy - What exactly are Solar Balloons?


Energy and metering
A year ago an exceptional concept in sustainable energy won the "Forward Thinking" award within the RE:VOLT Electrifying Ideas competition. What was this new idea? Solar balloons put together by Israeli scientists Joseph Cory and Dr. Pini Gurfil for Sun Hope.

Precisely what are Solar Balloons?

Historically the definition of "solar balloon" has described simple black balloons which were filled up with air. In accordance with Wikipedia, "as sunlight shines for the balloon, mid-air inside is heated and expands, causing an upward buoyancy force, similar to an artificially-heated hot air balloon. Some solar balloons are just right for human flight, but usage is limited on the toy market because the surface-area to payload-weight ratio is quite high."

As technology evolves, terminology evolves at the same time. Now the title of "solar balloon" may also reference a balloon like "platform" which has embedded photovoltaic arrays or solar arrays to be able to convert solar technology into electricity. When it comes to the Joseph Cory and Dr. Pini Gurfil's Sun Hope design we see a lighter-than-air helium filled fabric balloon because platform or base. Each fabric balloon is associated with the ground with two cables - one for helium refills, one other for passing generated electricity with a cp.

Sun Hope isn't alone of their quest for an economical, functional solar balloon design. Another solar balloon design comes from Cool Earth Solar. Cool Earth Solar uses plastic balloons which can be suspended on wires. To obtain a visual, visualize a 2 meter wide mylar balloon. These plastic balloons also provide concentrated solar photovoltaics where light is magnified onto solar panels to optimize electricity generation output. A common concern about solar balloons could be the capability to operate in high wind environments, as outlined by Cool Earth Solar, their system can withstand wind speeds of up to 100 miles per hour.

While solar balloons show promise being a photovoltaic implementation there are many concerns to become 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 placement of installation one may must consider items like air traffic regulations and potential bird collisions.

Solar balloons provide impressive value in isolated, off-grid locations and also temporary portable power supplies. In situations like these, solar balloons supply a approach to escaping a fossil fuel dependency.

Concentrating Solar Power

Both in of instances of solar balloons, the efficiency with the photovoltaic cells are improved by concentrating solar power (CSP). In line with the US United states doe, "concentrating solar power's relatively inexpensive and ability to provide power during times of peak demand - location we want it - imply it's really a major reason for the country's future needs for distributed causes of energy."

Concentrating solar power system work by making use of mirrors or other reflective surfaces to intensify the force with the sun to a specific point. This power of energy can improve the efficiency of photovoltaic cells. According to Cool Earth Solar, "multi-junction, best quality cells produced from satellite technology allow CPV systems to build the identical level of electricity as traditional flat panel PV systems with all the as much as 500 times less solar cell material." With diminishing resources of unprocessed trash necessary to manufacture photovoltaic cells, concentrating solar energy offers more energy with less garbage.

While today solar balloons are a new technology, sooner they might be a strategy to curing our nation of it's reliance upon classic fuels. The Cool Earth team recently received $21 million which they want to use to create a 10 megawatt plant utilizing their solar balloon technology. Thanks to forward thinking, environmentally conscious investors, a solar balloon based solar technology plant is often a reality over the following couple of years, someday it may even power your property.
