In honour of BlogActionDay, we're writing about our plans for making Scream an environmentally friendly boat.
Scream is currently equipped with a Diesel engine, which both supplies propulsion and provides electricity to charge the batteries. Like all Diesel powered boats, the engine is acceptably efficient at moving the boat, but it doesn't generate electricity efficiently.
We intend to equip Scream with several high-power solar cells, perhaps 190W Solar Spruce from Evergreen. We also intend to have a wind generator. Wind generators are increasingly powerful based on the length of their arms, but Scream has a very good place to mount a small one. We're debating whether to add an extension pole to allow us to mount a 1 meter radius generator or to live with a 50cm radius generator.
The big plan is to replace the diesel with an electric engine with regenerative power. Electric engines are available from Thoosa and Solomon for comparable prices to Diesel engines. We're looking at 50 HP models under $10,000. The benefits to this technology are many:
- No pollution
- No fuel costs
- Electricity is generated from the drag of the propeller while under sail.
We're committed to converting Scream from a 20th century fossil fuel boat to a clean and green boat to lead the way for the coming century.
