Man-made Fins Propel Swimmers Through the Water

Ciamillo’s Lunocet fins will make you faster than Olympic Gold Medalist Michael Phelps. The fins promise to propel swimmers up to speeds of 8 miles/hr, almost twice as fast as Phelps’ fastest clocked time of 5 miles/hr. The fins mimic the more efficient fins of dolphins and whales and can even push a swimmer out of the water.

While pictures are worth a thousand words - videos are even better:

What’s a Scuba Doo?

Here’s one that’s straight from the pages of a science fiction novel: A moped-type scuba machine called the Scuba Doo:

The Scuba Doo allows would-be divers to sit back, relax and enjoy the underwater landscapes without having to get any certifications. The diver’s head is enclosed in a glass dome (allowing for maximum view) and the air is being replenished by the on-board tanks. It cruises at speeds of up to 2.5 knots and can go down to a max depth of 4 meters (about 13 feet).

Because of its limitations, the Scuba Doo would probably not have any appeal to experienced licensed scuba divers. This device is probably geared towards younger people, people with disabilities or those who may not be ready to take a full certification course, but would want to experience going underwater. The hefty, almost 20 grand price will probably make this only affordable to the independently wealthy, but some reorts all around the world are offering rentals, with average rates around $130 per 15 minutes.
