"Maldives plans 18-hole floating golf course"

Here I was thinking the royal wedding was pricey, but then reader Rob sends me this Wired story by Duncan Greere about plans for a $500 million "floating" golf course.

The 18-hole course might sound like the kind of energy-guzzling project you'd see off the coast of Dubai, but it's intended to have zero footprint on its environment. It's powered by solar energy -- a resource that the Maldives has plenty of, lying as it does just north of the equator, and the development will also employ sustainable desalination and water cooling techniques.

The course will be made up of a series of floating platforms containing two or three holes each, which will be linked together and to a series of surrounding hotels by underwater tunnels. Waterstudio.NL designed the project, which is being engineered by floating-architecture expert Dutch Docklands. Troon Golf is on hand to offer their expertise in the design of the course itself.
