Re: [Phys-L] [SPAM] Re: solar constant

["Craft, Peter" <PETER.CRAFT@det.nsw.edu.au>]

A very quick search on trusty google showed up two experiments that may be worth the effort.

You have inspired me to give both of the above a try to see what sort of results they yeild.

Thanks! Can you send me that article, or is there a web link?
