what does the sun have to do with technology ?

it many substances lik light helps people travel or u can go to google

Converting sunlight to energy requires solar panels, which involve technology.

Since this is not my area of expertise, I searched Google under the key words "solar technology" to get these possible sources:

http://en.wikipedia.org/wiki/Solar_power
(Broken Link Removed)
http://en.wikipedia.org/wiki/Solar_cell

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. "Sun technology" got only listings of specific companies, so I tried "solar technology." Although I got more company listings, it included some informational sources.

I hope this helps a little more. Thanks for asking.
