Electric Jet Boats From Enevate and Sealence Collab
An electric jet boat may result from the collaboration of two companies: EV battery tech company Enevate and electric boat propulsion company Sealence.
Italy-based Sealence has developed an electric propulsion system called DeepSpeed that operates silently and reduces vibration for sea craft ranging from fast tenders to large yachts.DeepSpeed electric boat jets can deliver from 250 horsepower to 1,300 horsepower, and the company claims that the jets feature energy-efficiency parameters that are higher than propeller-based naval propulsion systems.
DeepSpeed requires battery performance similar to Enevate’s EV performance specs: namely, high-energy density with high discharge rates, long cycle life, and extreme fast charge capability.
(Via Electrek)
As far as I know, the first reference to an electric boat is found in The Great Drought by Capt. S.P. Meek, published in Astounding Stories in 1932:
(Electric boat from 'The Great Drought' by Capt. S.P. Meek)
Before the doctor’s surprised gaze, the edges of a huge box rose above the surface of the water, around the electric boat. The boat was raised and water could be heard running out of the box which held it. When the box was drained, a man leaped in and made some adjustments. A cover, hinged on one side, swung over and closed the box tightly with the boat inside.
