For all those people out there wanting to go GREEN - there's a new yacht available - called the Island Pilot DSe Hybrid - that is powered by an electric/diesel hybrid engine. I believe I've stated it before, what is considered alternative today, will become common-place. Hybrids are going to be the rule, not the exception over the next few years. In ten or twenty years, Gasoline/Diesel engines will be considered antiques and collator's items.
Here's a business idea for someone -- how are we going to deal with all those "old" vehicles (not all will be collectibles) when they start to be discarded by their owners? There's lots of salvageable items - start thinking about that.
