I am planning a solar concentrator for a later use on free piston Stirling engine.
for the said purpose following are required
An 8-10 ft Solid Satellite Dish (preferably a solid one)
local or used may suffice. what are the costs involved? and where to get these in Lahore? probably Hall Road?
Solar Tracking Arrangement (dual axis)
i have heard of some remote motorized alignment arrangement which is supposed to do the job very well.
At first the above mentioned arrangement will be used for heating water.
