"The concept is a simple one, borrowing from some very
elementary principles. For instance, everyone knows the best way to capture and
contain the most of an element or substance is with a funnel. These cones make it easier to put oil in our
cars or fill small glass shakers from a larger bag of sugar.
Now, some MIT engineers have worked out a
computational model which shows how solar energy can be more or less
funneled before it’s captured, ensuring an efficient and effective solar energy
capturing mechanism."
