Absolutely Cool Application Of Technology

My buddy Ron sent this link (here) to me yesterday.  Man, if I were independently wealthy, and had no need for money to pay my bills, I would quit my day job and contrate my 2 dozen years of engineering experience to perfecting these types of mechanisms, to help advance and improve the lives of those who have little or nearly nothing in the world.  Tip of the hat to Rufus Blooter.  Very cool stuff.
