The Super Aviator is a personal submersible designed like an aeroplane. But its first aim is to explore ancient ship wrecks. It is electric and so eco friendly and also noiseless. It can dive to a depth of over 1,000ft at a top speed of six knots. It can dive for four missions of one hour per day or a one four-hour long exploration mission. The creators say that it is the “closest feeling to what flying is like in your dreams.” Billionaires as Roman Abramovich and Richard Branson have already made requests to buy a £1,5 million sub.
