If you're looking for a lighter-than-air yacht, 21st Century Airships builds highly advanced craft that can be used for promotions or just for fun. Powered by a hybrid diesel and electric system, the spherical orbs can have a full luxury cabin built inside for their lucky occupants. These airship yachts can be custom built to exacting specifications and can lazily float and fly cross-country or even across oceans.

21st Century Airships is even working on projecting full-motion text or video on the inside of these spectacular craft, and can build them with just about any design on the outside. The company is also experimenting with high-altitude airships which could be parked at 65,000 feet in the stratosphere to be used for cellphone antennas and other communications.
