It's not often nowadays that you see a product that really makes you wonder about the sanity of its creators.

Meet Rinspeed Squba, an electric Lotus Elise that goes up to 75 mph on land ... up to 5mph on water and up to 2mph submerged.

This is one item where you really have to see the video to be impressed. Check out the second one where the intrepid Top Gear magazine reporter takes a drive ... and a dive.

Like the Tesla Roadster it's based on the versatile Lotus Elise. An open model. If they closed the cockpit it would have to weigh tons to offset the bouyancy of the cabin!

Practicality factor about zero, cool factor off the charts. 750,000 British pounds (about $1,250,000) buys you one.

To fund his search for the legendary Titanic, Bob Ballard asked the US Navy for money. They said no ... unless you help us out by looking for two lost submarines.

And that's exactly what he did, finding debris from the USS Scorpion and USS Thresher, two subs that sunk with all hands during the 1960s. He discovered that contrary to the Navy's fears, there was minimal environmental damage from radiation from the two ship's reactors. He also determined that the Scorpion was sunk by one of its own torpedos and not Soviet activity as suggested.

Then, using the same techniques he perfected finding the subs, he was able to locate the Titanic.
