I goofed here.I should have said that glass blocks uv radiation and quartz does not.So quartz allows more light energy through it than glass(ie,more wavelengths).Although what I said about ir radiation going through glass was correct.I may not be right about about quartz blocking it(ir radiation).Triffid

For those of you wanting pirate satellite TV doing a web search on "satellite rookie" is a good place to start.Some one in this thread earlier mentioned satellite recievers.It is up to the broadcasters to secure their signals.If you happen to have a receiver that can pick them up.You are pretty much ok
unless you sell copies of broadcasts or rebroadcast the programs.Triffid

Kampen, if you could make a mirror diffuser(a half coned cylinder lined with mirrors on the inside) at the focal point it would bounce the solar energy to narrower part of the cone.  At this point you add a mirrored tube containing magnifying lenses. This would shape the rays into a beam-solar laser.  The only real complicated part would be directing it-would need a mirrored sphere with an apeture eye that could open/close and rotate the ball to direct it.  Then you could heat or not heat stuff from distances away from the dish.  I designed something like this my last time in afghanistan.  The system consisted of a 300m aluminum polished dish with all those listed components that operated in a system of 12.  This way there would never be a lack of solar power to any one.  They could beam energy from one dish to another, from the day side to the dark side from one to one or from all to one for max power.  We could grow crops at night by opening the eye all the way or focus it into a narrow beam for either heating up water or blasting stuff into ashes.  I'm sure the atmosphere would react in a bad way not to mention burning away cloud cover and messing up weather patterns.  But then again it was just an idea of 24 hour solar power.

@ All,

Looking/searching for a small circulating pump, mustbe heat-resistant because I intend to circulate oil in my Parabolic Solar Heat Absorber. Any advise/help is welcome.

Thanks in advance.

 The parabolic dish is so simple. Such an eloquent way to make power.

 This guy has some experiences with making parabolic dishes to use as power sources:

http://www.youtube.com/user/GREENPOWERSCIENCE

 A parabolic dish power source can be compact too. A 24" dish is capable of making a few thousand watts of electricity on the fly.
 The problem, of course, is converting that energy into electricity efficiently.

 I love the idea of the solid state Peltier device converting power/sunlight from the parabolic dish. But most Peltier devices are inefficient at the moment.

 However, this company claims to have an answer to higher efficiencies, 70-80% of Carnot efficiency. Very useful to the parabolic dish setup.

http://www.powerchips.gi/technology/pcalc.shtml

 There must be a way to make these "solid state thermal electric generators" cheap and plentyful.

I envision a 36" parabolic dish on the roof of my RV, tracking the sun as I camp.  Providing 3500 Watts of power on the fly, and charging my 8 deep cycle batteries.

Any inputs?  Any homebrew ideas?

Hi Kampen.

You'll get your greatest efficiency by building an efficient wave guide, one that traps the heat and radiation the longest within the wave guide it self, Aerogel has a 99.98 efficiency at trapping heat and bouncing it around so you may want to look into that for making a wave guide block, one side of the Aerogel can be mirrored to help trap other frequencies of radiation as well.

If you need some engineering advice on building a Radiation Wave Guide Trap just ask and I will see about looking into parts for you to assemble.

I see that you are using a oil based medium to conduct heat? there are better Heat Moderators that could increase the efficiency even higher.
I could show you how to make a Ultra high efficient Heat trap but the only draw back is the very expensive materials needed, they are not cheap at today's rates of scientific instruments.

The perfect energy production system
1. uses no moving parts.
2. converts all band gap energies to usable energy.
3. made of ultra light material.
4. made ultra transparent for optimal radiation transmission.
5. utilizes Radiation traps or internal mirror wave guiding to reuse trapped radiation within the confines of the solar photovoltaic optical cell. (recycles its own radiation near 100%).

these are just 5 of the attributes to a ultra efficient power production system. no motors or engines could keep up with such a system.

on a secondary thought besides the one above, it may be possible to use a magnetically confined ultra positive ion plasma to attract negative Electrons to a capacitive surface trap that conducts the Electrons away from the +++ Plasma attractive source, this is just a thought and nothing more.

It's a Dual-Axis SatDish Motor (36VDC) from JAEGER.
