We had some really great threads last year, with the following four nominated for the Thread of the Year award in this January's Environment Site Awards ceremony.
Solar Energy ForumI have no doubt that we will be successful in harnessing the sun's energy.... If sunbeams were weapons of war, we would have had solar energy centuries ago. ~Sir George Porter
Guys... i really need a simple way (simple!!!) to make a small solar collector... should be the size of max. and A3 or A2 card... it's for school... namely physics, if you could provide me with any ideas... coz i see these pages : "simple solar collectors" and what do i see!!!!???? i see a huge piece of metal like 5 metres long n wide...
any other simple solutions?? well i mean such things that would show my teacher i've actually done a bit of work, not just went to my neighbor for a piece of pipe and paint it black... i want it to look like it took me at least 1 hour to make it... but in fact like 20 minutes.
