World's First 3 Underwater Submarine Cars
3.
Rinspeed sQuba
Motoring enthusiasts can now buy a $2 million (£1.2 million) sports car that can be driven
underwater.
The sQuba, developed by Swiss company Rinspeed, is the world's first car that can be driven
both on land and under water.
The original idea by Rinspeed founder and CEO Frank M. Rinderknecht was inspired by
the 1977 James Bond film The Spy Who Loved Me.
The chassis from the Lotus Elise is used as the base for this vehicle.
The sQuba is a zero-emission, all electric vehicle which uses three electric motors,
one for land travel, two for water.
It drives on land powered by its electric rear-wheel drive powertrain, utilizing rechargeable
lithium-ion batteries.
Upon entering water, it floats on the surface until the operator floods the interior to
submerge it.
It can be submerged to a depth of 10 metres (33 ft), powered by twin electric-powered
propellers supplemented by two Seabob water jets.
It "flies" when underwater, like a submarine, as it is not designed to drive along the surface
at the bottom of the water.
The car's top land speed is 120 km/h (75 mph).
On the surface of water, the top speed is 6 km/h (3.2 kn; 3.7 mph) and underwater it
is 3 km/h (1.6 kn; 1.9 mph) The vehicle's interior is water and salt resistant
so that it can be driven in the ocean

Wet Nellie
Wet Nellie is a custom-built submarine, created for the 1977 James Bond film The Spy Who Loved
Me in the shape of a Lotus Esprit S1 sports car.
The Esprit was chosen to give James Bond a glamorous car to drive.
"Wet Nellie" is named in reference to Little Nellie named after Nellie Wallace, an autogyro
featured in the James Bond film You Only Live Twice.
It was built by Perry Oceanographic, Inc., of Riviera Beach, Florida, USA, specifically
for the film, using a Lotus Esprit S1 bodyshell, for about $100,000 at the time.
The wedge shape of the Esprit is designed to provide downforce, so would force the submarine
to dive, so was compensated for by fins placed where the wheels would be in a conventional
Esprit.
The sub would require a crew of two to operate.
It has four electric motors that allowed forward motion only.
It was put up for auction as a Bond Car in 2013.
In September 2013, the submarine sold at auction for £550,000, at RM Auctions in Battersea,
south west London.
Elon Musk bought the vehicle, and as of 2013, planned to convert it into the functional
car-submarine from the film.

DeepFlight Dragon
The $1.5 million Undersea Aquahoverer DeepFlight Dragon is the easiest submersible to operate
in the world because it hovers in-place without the need for adjusting ballast or managing
drop weights.
Requiring no more skill than driving a car, the sub's fixed positive buoyancy combines
with its six 400-rpm, 1.2-kilowatt ducted propellers-two front and four rear-to provide
easy unidirectional movement and stand-still hovering underwater next to reefs, wrecks,
and underwater species.
Capable of exploring the twilight zone down to a depth of 400', its streamlined composite
pressure hull keeps two explorers safe in custom carbon fibre seats, with acrylic domes
optimized for best underwater sightseeing.
Intuitive and fly-by-wire controls (from either cockpit), two independent digitally monitored
oxygen systems, and a closed-circuit internal (and VHF-to-surface) communications system
provide submariners with a safe, flexible environment for investigating underwater anomalies.
The entire craft is powered by a rechargeable 15kWH battery.
