Overview:

Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

First test flight of largest all-electric aircraft used just $5 of electricity (arstechnica.com)

The X1 aircraft is comparable in size to a small regional airliner and can achieve a maximum takeoff weight exceeding 25,000 pounds with the help of four wing-mounted electric motors. The battery-electric propulsion system delivered more than one megawatt of power during the maiden flight.

Curious how much fuel would have cost for a comparable flight. Could this make short flights significantly cheaper than they are currently? Or open up the possibility of flying with many short hops in some cases.

A 4-seat Cessna 172 burns 8 gallons of 100LL fuel per hour, so 4 gallons in 30 minutes. That fuel costs $7 per gallon at best. 4 gallons times $7 means it costs $28 for 30 minutes. That's roughly $1 per minute for the lightest aircrafts.

Some fuels are cheaper but they also get burned at a higher rate, so exact numbers depend on many variables.

@rimu@piefed.social pilots are expensive, and airplanes are also expensive to maintain- unless you skip the regular maintenance. This might be a little cheaper, but it still won't enable short flights for anyone not already rich.

The electric engines are easier to maintain than jet engines. Far less parts, especially not having to deal with fuel pumps and all the safety issues around fuel storage. Not having to withstand the huge temperature differential between the engine combustion and the high altitude air probably helps too.

Pretty sure fuel is still a fairly big part of the cost of flying. I wonder how the maintenance compares on an electric plane engine compared to jets too.

Planes are already cheaper than other options for short distances anyway, going electric would be great for that.

If you skip the plane and go with a drone style you can drop all the complex hydraulics and just have a dead simple electric motor. A large version with a flying wing shape could work well.

Those are vastly less efficient than a wing. They are great for slow speed and pin point accuracy at short range, which rarely matters.

If it works you can have a range extender medium size drone at the start and finish for mid air refueling by cable.

@Einskjaldi@lemmy.world

@rimu@piefed.social @HerbGrower@slrpnk.net maybe, but that is complex logistics.

[–] HerbGrower@slrpnk.net 2 points 4 days ago

Yeah, that sounds incredibly complex compared to just landing and switching plane or recharging.
