3D model of the AT catamaran (thermal energy conversion system). The AT catamaran is a catamaran design that is locally buildable and cheap, and which allows (emissionless) transportation of a relative large amount of cargo. It can also carry 4 people. The steam engine powered catamaran is powered by a firebox serving 2 Tesla steam turbines. The firebox is filled with desalinated water from 2 alambics. The alambics themselves are supplied with seawater using a pump. The catamaran is also fitted with suspension (leaf springs) which make the ship longer lasting, and also improve comfort to the passengers. It is also fitted with a caged propeller, and climbing harness and a control stand fitted with navigational aids. The steering is accomplished using the motors (more power can be given to either of the 2 propellers), and to some degree also by means of the electricly-operated tiller. 2 sea anchors and bollards are present for mooring.
