Waarom pleit u niet voor de elektrische tankers ?
Een gat in de markt voor Tesla ?

Electrische passagiersboten zijn er al (Noorwegen).
En geen kleintje, genoeg voor 360 passagiers en 120 voertuigen.
En geen sluikstorten van giftige lucht:

Green Power Mix
Siemens’ experts therefore installed one lithium-ion battery at each pier to serve as a buffer. The 260-kWh unit supplies electricity to the ferry while it waits. Afterward, the battery slowly recoupes all of this energy from the grid until the ship comes back again to drop off passengers and recharge. The charging stations are housed in a small building about the size of a newsstand. The ship’s batteries are recharged directly from the grid at night after the ferry stops operating. This solution is both simple and ingenious. “Under the prevailing conditions, it was the only feasible way of building and operating a battery-powered ferry,” says Moen. “Otherwise we would have had to expand the entire grid, and that would not have been possible due to the high costs of such a project.”
It isn’t just its drive system that makes the new ferry so environmentally friendly. Its electric motors are of course virtually silent and don’t burn any fossil fuels. They also don’t produce any pollutants. By contrast, a conventional ferry traveling the same route consumes around one million liters of diesel fuel and emits 2,680 tons of carbon dioxide and 37 tons of nitrogen oxide each year. Nevertheless, the real reason for the positive environmental balance is the electricity mix. “The electricity in this area is generated exclusively by hydroelectric plants,” says Moen. “This makes the energy the ferry uses cheaper than diesel. It also means the ship doesn’t emit even one gram of carbon dioxide, directly or indirectly.”
