Question by Mahesh: How are small images of the sun in partial eclipse,seen under the shades of tree during solar eclipse?
Prior to the total solar eclipse, you may be able to look at the shadow thrown by a tree onto the ground. Often thousands of small images of the sun in partial eclipse will be visible. How does this happen? Does this phenomena have any thing to do with the term,'Fraunhoffer Diffraction?
Best answer:
Answer by Roger KDon't know if it is related to Fraunhoffer Diffraction, but each opening between the leaves through which the sun shines acts like a pinhole camera to project the image of the eclipsed sun on the ground.

How can I set my house up for total solar power?
Question by zaynpevy: How can I set my house up for total solar power?
I am looking to find out how to go about setting my house up for total solar power? I live in the South so sun isn't a big problem for us. I'd really rather be using a sustainable product than keep letting the electric company keep charging me for THEIR gas usage. Exspecially when I see their trucks running all over town to run their daily errands instead of working.

Answer by Justin HYou really cant, it would take large ammounts of space and thousands of dollars in solar panels to even come close to a fraction of what a house uses. also solar panels create DC power which would have to be converted to AC in a dynamo or inverter... and there is always losses do resistance etc.
Also solar panels don't last forever, they have to be replaced every few years depending on the quality so in the end it's cheaper to stay with your local utility provider....no I don't work for one...
