How to Overcome Sea-Sickness and Become Amphibian

Soon ships causing no sea sickness will sail in seas and oceans, everyone can become an amphibia with no oxygene ballons and non-chargable fish-robots will appear.

Avoiding sea-sickness. Norway's Salt Ship Design shipbuilders together with Marintek Institute invented a new technology of Offshore Accommodation Vessel which decreases ship rocking.The technology is based on placing huge water tanks on the bottom and on the sides of a ship. Every tank has an air valve to regulate water motion inside them.

Offshore Accommodation Vessel engineers suppose that water motion in reservoirs will compensate the force of the waves. That's why the level of ship rocking will decrease considerably. The influence of tanks on the speed and other ship characteristics is yet unknown. But it's known that Hyundai Heavy Industries concern is now building such ship and it will be put in water next year. However it is planned to use it as a business-centre.

Breathe – don't breathe. Prototype of gills, respirator Triton, was invented specially for the fans of science fiction. Triton has a filter made from special water resistant threads which let oxygen get inside. Microcompressor pumps air into special reservoir so that you can breathe.

The only reason Triton is not manufactured yet is small capacity of today's accumulators, which can't let respirator work long. However the inventors hope that their gadget will be useful when accumulators with higher capacity appear. Unfortunately, Triton developers don't specify whether the air from this respirator will be breathable for a man or not.

Now I'm a fish-robot! AeroVironment company invented an ocean robot which works on sun enegry only. It's called Mola, in the name of one of the largest fish. The fish and the robot are similar in drifting on a surface. The robot, understandably, stays on the surface to charge, but why Mola fish does, scientists yet don't know. After all, she can swim well.

Robot looks like a transparent plate with fins and tail, with no accumulators. He spends energy to move. It's possible to put equipment on Mola, and he'll have speed of 2 knots per hour. Mola is yet a prototype, but AeroVironment is sure that future models will be used for automated water research.
