Uw woorden:
Elektrische vliegtuigen ..... zijn hybride-vliegtuigen.

Leesproblemen? Begrijp je Duits?

Zijn dit ook 'elektrische' boten?

Oh fijn dat je het over electrische boten hebt.
Waarom? Er bestaan veel soorten electrische boten naargelang (hybride) techniek, maar er zijn er zeker ook zeer grote bij die volledig emissievrij zijn = GEEN HYBRIDE.

Bvb deze ferryboten varen 100 % electrisch (en het snellaadprobleem hebben ze ook opgelost met een buffer) :

In conjunction with Fjellstrand, a Norwegian shipyard, Siemens has developed the technology for the world’s first electrically-powered car ferry. The fact that the ferry, which entered service in early 2015, causes no carbon dioxide emissions is in part due to Norway's electricity 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.”

Project specialists have also adopted a new approach for the ferry’s design. After all, unlike most electric cars, this ship was developed from the ground up as an electrically-powered vessel. This has had a noticeable effect on its weight in particular.
Despite its ten-ton batteries and capacity for 360 passengers and 120 vehicles, the ship is only half as heavy as a conventional ferry. That’s because it's made exclusively of aluminum rather than the steel normally used in shipbuilding. The ship’s corrosion-resistant structure also means it doesn’t require the special coat of paint that’s used to protect steel ships against rust. Its robust aluminum hull needs far less maintenance, says Moen. That too lowers the ferry’s operating costs. In addition, the ship’s designers searched for the most energy-efficient systems available.

Is het mogelijk om in uw titel ook echt te vermelden over wat het eigenlijk gaat i.p.v. te pas en te onpas te spreken over 'elektrische' tuigen?

Het gaat over het electrisch vliegen in de toekomst, je begrijpt toch Duits? En bij vliegen voor lange afstanden -met veel lading- zal het wel zeker hybride zijn (staat in de tekst), tenzij men meer gaat (traag) zweefvliegen (en voor heel weinig passagiers), en steeds boven de wolken waar zonne-energie de batterijen op peil kan houden, of natuurlijke hybride. LOL.

Weet je wat een range extender is? Al van een Opel Ampera gehoord? Van een BMW i3 met range extender ?
