sQuba - World's First Submersible Car

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 Lotus Elise is the basis of this car.

The sQuba is a zero-emission, all electric vehicle which uses three electric motors, one for land travel and 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 can transport a driver and passenger in its open cockpit. The open cockpit design is intended to allow the occupants to escape easily in case of emergency. When underwater, the occupants breathe air carried in the vehicle through scuba-style diving regulators. Without occupants, the sQuba will surface automatically. The twin water jets mounted on rotating louvers at the front of the vehicle provide steering and lift while it is underwater and the propellers at the rear provide forward movement.

The vehicle's interior is water and salt resistant so that it can be driven in the ocean.

The sQuba also comes equipped with a laser sensor system made by autonomous cruise control system to allow autonomous operation.

WiTricity - Wireless Electricity

Transmitting electricity through the air is now a reality.

Witricity, standing for wireless electricity, is a term coined by MIT researchers, to describe the ability to provide electricity to remote objects without wires.

Witricity is based upon coupled resonant objects to transfer energy between objects without wires. The system consists of a Witricity transmitter, and devices which act as receivers.

Like radio receivers, the devices must be in range of the transmitter. Currently the project is looking for power transmissions in the range of 100 watts.

The MIT researchers successfully demonstrated the ability to power a 60 watt light bulb from a power source that was seven feet (2 meters) away at roughly 40% efficiency.
