Can Floating Solar Balloons Power Remote Regions?

One of online order viagra the key stumbling blocks for supporters of solar energy is the fact that many of the planet’s sunniest spots lay in the try it viagra profesional middle of oceans or inhospitable deserts. Now a team from Israel’s Technion Institute of Technology have developed solar energy balloons as a means of harnessing the sun’s energy in exactly such remote areas.

The team argue that the devices may be a cheap way to power remote areas lacking either the land or the infrastructure to accommodate "traditional"-type large power stations.

According to the concept’s developer, Pini Gurfil, the idea is “to take advantage of the height dimension. When you do the best choice buy cialis generic that, you save a lot of only best offers cheap canadian levitra land resources and only now buy levitra pill can get to places otherwise hard to reach.”

The helium-filled balloons, available from around spring 2009, are covered with thin-film solar panels, and can float at heights of up to link for you cialis cialis several hundred meters. The electricity generated is cheapest 50mg generic viagra fed via a wire cable into an inverter capable of converting it for household use.

Initial research has shown that a typical 3 Meter (10ft) balloon should cost around $4,000, and be capable of producing around 1Kw of energy. This roughly compares to the same output from 25 square meters (269 sq ft) of traditional solar panels, at a cost of $10,000.

However, critics suggest that the system may have only limited niche appeal, and point to the widespread availability of "free" space on city rooftops and relatively low cost land around many urban centers. Now if they could get them to ten or twenty thousand feet...above the cloud layer, that would be another story.

And that would cost?

What would the cost/loss be of transporting that power 10-20 thousand feet down to ground level. What would the risk be to aircraft of having a giant cable... and... well there's lots of good choice discount drug cialis ands.

What would be cool, is if they could just fill them with helium and send them up to the space station for mounting. That, would be bad ass.
Can we say space and under water citys

Space - shoot it at the moon and bam we have a solar cells, outside of Armies space base on the moon (we all know its there)
Under water you could have it attached to a dome and then power the cities.

Very interesting thing... I think it's going to evolue with the time. Just wait & see smilies/wink.gif

I'm missing the point of this.

Some of the sunniest parts of the planet are large deserts where land is very inexpensive.

Just stick the thin-film (or solar thermal) on the ground where it's a lot easier to maintain. And a lot easier to secure against high winds.

Panels do need the occasional cleaning...

The only real place I could think where this might be useful is maybe an oil rig or something else out in the ocean where there isn't land.

Long tethers for high altitude, low voltage photovoltaic (or high altitude wind) will not work.

Keep it on the ground.
'Free' space but expensive panels
written by Flint, April 09, 2008
$4000 versus $10000 for the equivalent generated amount of electricity? That 'free' rooftop space is actually costing $6000! How high do these things float? If it's not so high that it affects aircraft flight panels they would be a fantastic alternative to expensive panels in urban areas as well, particularly in high density housing complexes like those that are common where I live.

Very interesting indeed. I still have a lot to learn when it comes to the many environmental issues that are before us. I have learned a bit of something new each time I've visited this blog and we recommend fda approves levitra I appreciate the education. Thanks.
does height make a difference?

I wonder if the solar collection is more efficient the higher it is in the sky?

When I look at some of buying viagra without a prescription the ideas that get thrown out I find myself wondering if the author has a stronger background in Photoshop than in Physics.

to keep the balloons floating one needs to fill them up with light gas.helium can be used but it is rare and can be obtained only through petrolium products,hydrogen cannot be used because it is a explosive.
so what gas is used?
