The engine is not new to the market with millions having been installed in the Smart Car, manufactured by Mercedes in Europe and Canada for the past 5 years. The complete unit installed weighs in at 9 lbs less than a Rotax 912, and can put out between 40 and 64 DIESEL horsepower.

The Pelena Express vessel does have a propeller - but it's located inside a pipe inside the boat. A screen or trashrack stops logs & coconuts from hitting and damaging the propeller...................

Pelena Energy of Australia has developed technology for reliably operating diesel engines on coconut oil (CNO). It is planned that the vessel will be operating on a blend of diesel fuel and coconut oil in late 2006/early 2007, after business establishment, and later on pure coconut oil. The aim is to eliminate the copra processing in villages and instead produce oil directly at the village level. This will provide income for villagers and minimise the dependence of Solomon Islands on imported oil. Of course, the minimisation of Greenhouse-gas emissions are also significant.
