Your Questions About Solar Power International

Maria asks…

Would a massive international solar-power station in earth's orbit help reduce global warming?

I know the idea sounds very outlandish but I think it may serve many purposes. I would think that this station could help power the new space tourisim industry. Also, we may be able to absorb enough of the sun's light to help reduce global warming.

I apologize for the misunderstanding. I have no intention to transfer the energy back to earth… instead use it to help fuel to emerging space industry. Construction could be completed in space since… we will soon easily break the atmosphere in small jets. And I was not trying to shade the planet but use the solar panels to absorb energy from the sun before it hits the atmosphere.

Sounds like you are on to something here, although with respect to the size of it, and if you are thinking that it will shadow earth to some degree and reduce the direct sunlight upon the earth and create energy at the same time which could be sent to earth by microwave then in theory it would be wonderful, although I believe you would have to design it in such a way, or by using special materials that the solar winds, solar storms, meteorites, and space junk would not destroy it.

Also depending upon the distance you place it from earth, and with respect to the diameter of the object then gravitational attraction will increase so you will have to maintain its orbit using thrusters and Ion pulse would be perfect for such a power plant.

Although the down side is that the further the distance from earth the more massive the object must be to cast the shadow, and the materials involved in such an object would cost trillions upon trillions upon trillions of dollars unless you were capable of making it tissue paper thin.

Additional details

How about producing a vast number of multiple power plants connected to very large solar sheets and pepper them at multiple distances from earth, and multiple distances apart, however between earth and the sun. This would be much more cost affective and would be perfect for filtering out the sunlight, as with respect to us we would not even be capable of observing them, but with respect to the filtration which would be offered it would be most effective.

With respect to the energy created you could send it to any receiver which you wish to send it by microwave.

Mark asks…

How much power does the International Space Station produce from its solar cells?

ssadmin answers:

Up to 131kW. Much of the time they do not generate nearly so much power though – the solar panels are often angled in a compromise configuration between between generating power and minimising aerodynamic drag. Less drag means less propellant is needed to keep the station aloft.

Laura asks…

How to solicit the services of a professional to orchestrate the design & construction of a solar power plant?

Product and international investors are in place and ready to commence feasibility study. The professional will need to orchestrate the feasibility study, design, construction, final intergration, energy marketing, energy distribution, energy efficiency, and ongoing maintenace of the solar power plant(s).

ssadmin answers:

Place a free ad @ http://www.buildersstaff.com. There are professionals of every trade looking for opportunities. You will probably get many responses and excellent pricing.

Chris asks…

What are some rising, or already well established, solar or wind power companies?

International companies are acceptable as well. Does anyone know of any companies which are in the solar or wind (or any alternative source of energy) power industry? Or any innovative companies as well.
Thank you

I think rather than asking people here you'll get better results by searching for the answer in Google.

Ruth asks…

Could concentrated solar thermal generate 25% of world power by 2050?

A new study by Greenpeace International, the European Solar Thermal Electricity Association and the International Energy Agency considers three different potential scenarios for concentrated solar power‘s (CSP) growth over the next few decades. In the third and most aggressive scenario, we could see CSP generating 25 percent of the world's electricity by 2050.

The scenario includes increased investment in the technology to $29 billion a year by 2015 and $243 billion a year by 2050. These investments would lead to installed CSP plant capacity of 1,500 GW by 2050. The second scenario saw more modest investment increases and a total capacity of 830 GW by 2050, still an impressive 12 percent of the world's energy needs. The first scenario assumed no investment increases at all, with CSP making up only 0.2 percent of the world's energy.

The technology has been taking off recently. Spain alone has 50 projects in the works and will be generating 2 GW from CSP by 2015. Worldwide, CSP currently makes up 436 MW and investments in the technology will reach about $2.8 billion this year. Based on current global plans, by 2017, close to 20 GW of CSP capacity will be installed.

Realistically, how much of the world's power do you think CSP can generate by 2050?

ssadmin answers:

Realistically? Don't ask me that. I'm a pessimist. To many political problems.

Optimistically? Close to 100%. Easy. It's just a matter of will.

Balancing the two, 25% seems reasonable. But we are soon going to realize that 25% won't be enough.

We need to do something like this –

– and we need to start now.
