Propellerless marine engine developed | HardwareNews
based in french finx The company obtains thrust by fluctuating a membrane with magnetic magnets. The thrust created in this way does not cut or shatter anything in the water, does not get tangled up in anything, and does not make any noise.
For now the small engine is just 3 tons It can be used in vehicles such as inflatable boats, but in the future 100 kW (150 HP) An advanced version with more power will be produced. This engine will also be used on cruise ships. It is also planned to use hydrogen fuel cells in this model.
Batteries that can be changed to giant electric trucks in mining facilities
Since the system has no moving parts, maintenance costs are very low. For maintenance, it is sufficient to remove the elastic membrane from its bolts and replace it with a new one every 2-3 years or every 1000 hours.
More economical engine for the same price
Price of the device 3000 € designated as . According to the company, it is sold at a price close to fossil fuel engines of the same power. Membrane fluctuation technology works even more efficiently than fossil fuel engines. In addition, this system provides around 30% extra profit compared to propeller electric motors.
Regarding the battery, the system can work with any 48V battery and offers 1 hour of operation if it operates at full speed with the battery offered by the company, and 6 hours if it operates in efficient mode. A special battery or hydrogen fuel cell is being considered for the next model. The current version has an open cable going from the motor to the battery. In the new version, the entire system will be larger and heavier than it will be in a box.
