Backyard Aquaponics
A place to discuss aquaponics

Apparently it is that simple, there was a company called Sun-Trac which used this principle to track the sun to heat water (solar style), we had one but one of the big companies bought them out and shelved the idea.

Highlight of every dawn was to race out and watch the panels roll over as the sun heated one side of the coil, basically had 2 pipes running parallel with a divider in between as one side got hotter the solar panels would rotate until both pipe fluid were equal in temperature - had it for over 12 years.

dang, wish I had seen one of those - no computers, just physics!

Les, did the heater die of old age? Why don't you have it any more?

Some of the mechanical parts wore out and replacements were not avail, we had a mechanic who worked for SunTrac living nearby and eventually he just couldn't keep it working properly - bummer really, it was a lot more efficient then the flat solar panels.

The principle behind the tracking device was soooo simple

poop, that must have been really disappointing

sing me up for this one

Remember it now - worthwhile somebody having a crack at incorporating it into AP - a project for later

I see the link is just a diagram ... makes it all seem just too easy ...

would it work?


I guess like the autosiophon we all worked through (and had so much fun messing aroound with) , it will take time, but I have a gut feeling that this one would a a lot more difficult to nail if at all possible.

Anyway, here's to the drinking duck! (Remember them.. pivot duck thingo, some glass tubes, and evaporation made the siphons do their thing!

(I that is essentially a fuidyne engine).

Would be nice to see it on a workable scale .....
even 1 ft lift ...

Hee Hee...

different thing, i think.

i reckon it might be a go-er, but not with just "incident" solar radiation. you'd either need a concave mirror reflector to conc. the sun, or a source of waste heat to get it to pump useful volumes.

Around here we have solar water heaters that the water is acutally boiling when it comes out, even on a rainy day.

Its done useing a copper pipe placed over a coper plate and all painted black then enclosed in a glass box.

here's a pic

Yep ok, what i should of said was the air reservoir alone won't collect enough solar radiation. If you used a very small solar hot water setup and wound the pipes around the air reservoir then that might just do it

A few years ago i had a erickson rider hot air engine it weighed 1 1/2 ton it was designed to pump water it burnt a lit of wood and dident pump much water these were not designed for economy. If you have plenty of time buy all means muck around with it [ has enyboby thought of having a go at perpetual motion if you can crack it that would be something]

hey j can you shorten it to this:*Example*
its run it off the page

Thanks Ell. (I know how to do it .. I just don't get the time!) Well thats my exuse! Hee Hee!
