Trying to find super cheap way to collect solar

[infringer]

I gave a fairly good idea on a solar project some time ago but no one cared to discuss it it is cheap ...

Look up the posts by me...

Or I can briefly explain the concept here ...

Magnifying glasses cheap ones at the proper distance aligned around a tube full of water metal tube copper is fine... A tube about 1 - 3 ft in diameter with a ton of cheap small magnifying glasses to concentrate the sun onto the tube at all hours of sunlight...

If done properly cheap and productive.

I think everybody's ideas on solar energy is important.I have seen solar collector designs that do not use foil but use a white surface with a black pot inside a  clear plastic bag to keep the warmth in.Great for countries where foil cannot be had for the price. everybody keep posting.triffid

Infringer,your design is similar to one of my projects.I came up with a burning mirror design that could generate up to 10,000 degrees.I want to use it for solar powered rockets.If I could find a material (metal or ceramic)to soak up the heat we could probaby use seawater for fuel and let the rockets take off at sea level.triffid

Actually you can buy sheets of Fresnel lens at office supply places.
These sheets are about 30cm x 30cm in size and they can light a piece of wood on fire very quickly.
They sell them for book reading lenses, because you can place the sheet across the whole page.
These would be ideal for focusing the suns rays on any type of collector.
Here's a video of a large one at work.

They used to sell large ones you could place across your TV screen to turn a smaller screen into a larger one.
