This is good for hot water but I think it will cool off at the end fast enough when high pressure.. I think I will use a mirror like that one day because it makes a longer beam, than a round or oval mirror. I still like my oil and pyrex idea=) I just need to go bigger. what’s great about the oil is it will heat all around the pipe instead of just the bottom, but you got some intense heat with that!! I think This is More usefull for Canada because we get the coolers temps. – more to heat.

GREENPOWERSCIENCE really worship the sun…

I hope someday they make a usefull use of it…

I don’t think it takes much imagination to extropolate this into “usefullness”.

Great vid Dan.

So flowing watter how hot it gets?

Good job, guys. That looks hot! I only had $5 for my solar experiment, but maybe that’s a good thing. We need cheap power, too… I’ll post what I got. ‘Keep em comin’!

Could you attach a small fan and some ducting to make a solar convection oven?

Hey Dan , Great coffee maker.
I’ll bring the donuts, you make the mudd.

By the way the wooden pipe holders might get a little hot if the sun shifts to the side a little. maybe not.

It’s cheating to preheat the pipe then run water through it. The real test is how many degrees can it heat water at a sustained (and measured) flow rate? If you had those numbers we could calculated the watts you are getting.

Hey guys.
After looking this video I think that center point this through mirror is not exactly at the center,…. is near by. And photons from sun will hit this black pipe only hour, maybe two. Is not so easy to create something like this. I konw that because I made the same project half year ago.The curve ( arc ) of mirror you must calculate very exact.Exist appropriate range of curve when center point can stay a long time.Also angel of all contruction is very important.

im thinking of a hot water heater … (wonder why:) but in order to heat a sufficient amount of water – would you run multiple pipes or make a presurised single loop with a heat exchanger. similar to the steam generators on my Nuclear Submarine. My next question is how much “heat time” would you get from 1 day? does the focal point follow the arc of the sun or is it fixed and only works at “High Noon”?

Love your vids Dan.

Dan I would love to see some data on steam production, psi, water flow rate.

I would like to build this twice as long. make everything automatic. and produce power through a steam engine to a dc generator then to a grid tie inverter. Can this be done efficiently or am I a dreamer?

Any ideas on how to deal with snow? It looks like the trough would fill up and brushing it off could scratch up the mirror. Maybe put the whole thing in a glass enclosure like the oven you made?

Yes you can enlarge the system dan built. At my home in Cape Coral Florida I used a 8 ft by 24 foot trough and produced 6 KW with plenty of preheated water for my hot water heater

Cheap, clean energy! But how does the pipe get hot enough?

By: locouk

If you paint half the pipe mat black (Lighted side) with small heat sink fins, and the other side polished or high gloss white you’ll find alot more heat will be generated with a slow but constant water flow. This could be used for a small steam engine and geni… this solar could be really useful to your average bod!

i been dying to make this parabolic mirrors and could you please help me out how to make my own??? Making your own looks simple and i need the design setup on how to make my own so i can use my natural resources. it would help me a lot. we dont qualify for energy assistance so i need to make my own due to high electricity bills and heating bills.

Hey Dan nice work
There are alot of folks that would like to know if you could drag this setup back out and Place an orifice aka “pipe cap w/hole drilled ” limit flow to a few gal per min and do a temp check for out put?
Thanks Keep up good work

You touched the water?

Wow you’re a dumb ass. Solar water heaters a common. Did you think it’d just be lukewarm?

Very nice setup. As AcidRaZor already said, I too cant wait to see a steam engine and a motor connected to that rig. If you do this, please include info like what type of generator is best for the job as well as some measurements like rpm, temperatures, voltage/current, materials for the tubing, etc. Thanks and keep up the good work.
