softdragonz Posted December 6, 2005 Posted December 6, 2005 Undoubtedly we are paving way to the renewable sources of energy. I assume that intensity of heat recieved by a body from a star decreases as we move away from it. (the surface of temperature of mercury is much greater than that of Pluto) I was wondering that instead of having a solar energy system inside our planet, why can't a solar system be sent into space as close to the sun as possible.....perhaps more energy can be derived that way.....to server generations
timo Posted December 6, 2005 Posted December 6, 2005 What do you do with the energy your solar panels collect, then?
Asimov Pupil Posted December 6, 2005 Posted December 6, 2005 Why not just wait for a very efficient fussion generator? you wouldn't have the problem of building a panel to send into space and then when you get the energy you would have to bring it back somehow.
TheDMan05 Posted December 6, 2005 Posted December 6, 2005 The energy could be transfered to a receiver on Earth in the form of microwaves. It would be a very efficient method of transfering the energy that is collected.
Klaynos Posted December 6, 2005 Posted December 6, 2005 right so you're going to collect electromagnetic waves with a big thing that will take LOTS of energy to build and send into space in the correct position and then transmit using some probably very lossy method other em waves to earth to be collected by another lossy collection method?

Sisyphus Posted December 6, 2005 Posted December 6, 2005 why can't a solar system be sent into space as close to the sun as possible..... At first I thought you were talking about moving the Earth closer to the sun... On a related note, try googling "Dyson spheres." The logical extension of what you're talking about. 1
ecoli Posted December 6, 2005 Posted December 6, 2005 The energy could be transfered to a receiver on Earth in the form of microwaves. It would be a very efficient method of transfering the energy that is collected. That would be a big waste of energy. the amount of energy to build the "solar system" and sending out into space, converting the energy into microwaves, and building a system to convert this into usable system... not to mention that Microwaves are more dangerous then heat. Anyway, its pointless to convert the energy like this.
silkworm Posted December 6, 2005 Posted December 6, 2005 We're not that desperate for solar energy that we need to go and get it. There's more than enough sun that hits the surface of the Earth to supply our energy needs. We just need more effecient and durable panels and better batteries.

silkworm Posted December 6, 2005 Posted December 6, 2005 Ecoli, Did you hear that there has been such a solar boom in California that panels are backordered for 6 months? It's just something I heard and I was hoping it was true.
ecoli Posted December 6, 2005 Posted December 6, 2005 Ecoli' date=' Did you hear that there has been such a solar boom in California that panels are backordered for 6 months? It's just something I heard and I was hoping it was true.[/quote'] no... I haven't heard that. I'd say it's good news, but if there back ordered that means people aren't getting their solar cells! Seriously though, I know about two are three households that are currently using solar cells where I live. Which isn't bad, considering I'm not living in "sunny california." My parents are seirously considering getting them. We just hav to figure out how long before they pay for themselves. cost is always a factor. But with increaing oil prices I'd say we will get them within a year or possibly two.
softdragonz Posted December 7, 2005 Author Posted December 7, 2005 That would be a big waste of energy. the amount of energy to build the "solar system" and sending out into space' date=' converting the energy into microwaves, and building a system to convert this into usable system... .[/quote'] Of course the energy to build a solar space system would be darn difficult...but think what would happen after you build it. It would stay there for a BILLION years.....(average life time remaining for the sun) Definitely the first nation to do that would seriously release its wrinkles on energy crisis (...provided the system works ) READ THIS: According to an April 2000 article in the Electric Power Research Institute (EPRI) Journal, photovoltaic arrays in a geostationary Earth orbit (at an altitude of 22,300 miles) would receive, on average, eight times as much sunlight as they would on Earth's surface. That means, closer to the sun, more the energy Now, even if we install a solar system near venus or something......do we experience power transmission losses?? Perhaps it would be better to transmit the power generated in some form of electromagnetic radiations...as they travel fast minimising losses
Quantoman Posted December 7, 2005 Posted December 7, 2005 would it be better to try to collect the antimatter from the sun? i think it would be worth the effort and energy if we could get a pound of that stuff.
Klaynos Posted December 7, 2005 Posted December 7, 2005 would it be better to try to collect the antimatter from thesun? i think it would be worth the effort and energy if we could get a pound of that stuff. Even if we found a way of capturing anti-matter from the sun (tbh I wasn't aware of it emmiting much/any) how would we store it?
Klaynos Posted December 7, 2005 Posted December 7, 2005 We'd have to make a fully evacuated box and then expend lots of energy creating the magnetic field :|
[Tycho?] Posted December 10, 2005 Posted December 10, 2005 but it would be worth it? As far as I know no antimatter is emitted from the sun, I dont see how it would be since it would have to be created apart from any mater for it to make it away from the sun. Then if you captured it in a magnetic field you would also caputure all the normal matter charged particles of which there are many..... So no, it would not be worth it.
Kermit Posted December 11, 2005 Posted December 11, 2005 You know, antimatter-matter annihilation converts every single bit of mass into energy.. that's a 100 percent efficiency right there. Maybe we should ask Leonard Nimoy.
softdragonz Posted December 11, 2005 Author Posted December 11, 2005 You know' date=' antimatter-matter annihilation converts every single bit of mass into energy.. that's a 100 percent efficiency right there. [/quote'] As per the brief history of time, the particle accelerators that are required to produce anti matter would be at least as large as the solar system ..... which is unfortunately not possible as per present economic conditions

Then if you captured it in a magnetic field you would also caputure all the normal matter charged particles of which there are many..... -antimatter is when a high-energy proton in a solar flare collides with carbon, It can form a type of nitrogen that has too many protons relative to its number of neutrons, This makes its nucleus unstable, and a positron is emitted to stabilize the situation. -Looping eruptions on the Sun create antimatter. -i am sure if we would attempt to collect the antimatter with a magnetic trap we would also know that it would have to filter out matter... ___________________ free thinkers need debunkers and debunkers need free thinkers
Klaynos Posted December 11, 2005 Posted December 11, 2005 I feel that that anti-matter probably anihilates long before it ever reaches us... How could we filter out matter?

It has been possible to create anti-matter for several decades now at CERN. In extremely tiny quantities, but definately created. I remember that passage of the book, and whatever he was talking about I dont think it was anti-matter. -antimatter is when a high-energy proton in a solar flare collides with carbon' date=' It can form a type of nitrogen that has too many protons relative to its number of neutrons, This makes its nucleus unstable, and a positron is emitted to stabilize the situation. -Looping eruptions on the Sun create antimatter. -i am sure if we would attempt to collect the antimatter with a magnetic trap we would also know that it would have to filter out matter...[/quote'] There is no way that kind of beta decay (sounds like it would be beta decay anyway) would form nearly enough anti-matter to be of any use. The vast vast vast VAST majority of it would just hit some particle nearby an annhilate itself. How is anti-matter created from looping eruptions? (I assume you are reffering to solar flares) Regardless, it would suffer from the same difficulty of there being too much matter around for the anti-matter to collide with. And how could you filter out matter? You would have to somehow filter protons and atomic nuclei (which are positively charged, like positrons) as well as any free electrons, which are the same mass as positrons. Seems hard to filter. Plus your filtration system couldn't use much energy, otherwise you'd end up using more energy to filter then you would gain from the anti-matter. And if we want to go into technicalities, how do you propose actually getting usable energy from the anti-matter?
