In a time of $4 per gallon diesel fuel, Christian Wyler has skills that could make oil executives shudder. For the past four years, the Garrard County High School senior has been making biodiesel in his own back yard. The fuel that Wyler makes now goes into the diesel engines of his father's Volkswagen Jetta, as well as much of the equipment on his grandfather's Lincoln County farm.

As an emergency room physician, I realized something had to be done when I repeatedly found people struggling with a widespread problem that needed a solution - getting medical care on nights and weekends.

As a result, I established FreeMD.com so that people can get immediate answers 24 hours a day about what may be wrong and where to go for appropriate care.
