As if we didn’t have enough to worry about this kind of nutty business pops up. What’s wrong with these people ? This won’t work😧 https://www.thedrive.com/the-war-zone/43838/spaces...ome-images

There is A LOT of misinformation posted here, on basically every topic that comes up, electric vehicles and otherwise.

Thank you.

As a test bed, it's pretty slick. Add in solar panels on the wings for in-flight recharging and it might be a viable option.

It's amazing to me that electric vehicles have been around since the early 1900s and we're only recently considering them a viable option. As a nation, we went from not even having put a man in space to putting men on the moon in just over 8 years. Why did we drag our feet on this?

Hope the poor bastards don't try flying out of a major hub during any high volume times. Can you imagine the frustration of having to head back to the gate for another recharge because it took too much battery power during the taxi out and subsequent wait in line to take off (you're currently number 38 in line, says the tower).

I'm curious what they're using for flight control actuators, as well as what kind of setup it has for pressurization and heating/cooling. What kind of redundancy is there in the event of electrical bus or battery failure? Does everything run off the battery packs or do the motors have IDGs attached, possibly even ram air turbines for power generation inflight?

I can see no upside to that apart from possibly gaining a bit of charge on decent for an emergency go-around. The rest of the time the weight and drag would eat more battery power than would be gained.

Late 1800's

First one in the 1830's.

Solar panels on the body (wings) would be far too cold at 30K . Maybe some day when they invent clear aluminum.

Only if they intend to transport a pair of humpback whales through time. :wink:

answer = cheap oil, readily available
It is only the development and demand for easily portable devices that has spurred the progress on battery performance.

This was routine until ATC learned to manage traffic from gate to gate. Now you don’t leave the gate until you have a landing slot at destination. You might stop in the penalty box worst case.

As far as battery technology, I rest my case.

The term "petro-dollars" comes to mind.

FYI - It's already real, just really expensive last time I checked.

People are in Love with conspiracy theories!
Everything is some big evil plan.

What was the electric vehicles problem in the 1910's?
Short travel Range
Long recharge times.

Gasoline however gave you unlimited travel distance and a refuel time of mere minutes.

The same issues are in play today.
Range and charging time.

Not to mention in 1910 MOST of the Nation didn't have electricity!
An electric car isn't much use when you have nothing to charge it with.

How much petrol does it take to make a electric car battery. Well you have to mine the ore, transport it, process it, etc. The what do you do with it when the battery is expired. How much cost is it to install a charging station, well you generally have to dig the ground (petrol machine) pour concrete (petrol machine) and so forth and so on.
Personally we like to cover about 600 imiles a day...cannot do that with a battery sorry the charging times would make the arrival late in the evening.

Charging times for a Tesla at the stations is only 15-25 minutes depending on how much you charge you want so you could do that when you stop for food/bathroom breaks

With the Supercharger (tm) 200 miles in 15 minutes.

That’s impressive. A 15 minute break every 3 hours is totally reasonable even to this anti-electric wanker.

Imagine stuck in that snowstorm in Virginia in an electric vehicle, charge runs out they can't bring a charging station. You're being towed, to say nothing of blocking the road until s tow truck comes

We already have a thread about the snowstorm. :wink:
Electric cars don't use much power when they aren't moving. Also, https://www.geekwire.com/2013/aaa-electric-charging-mobile/

AAA answers half a million calls a year from people who have run out of gas. And lots of people ran out of gas while stuck in the snow.

Last I heard they may be discontinuing the remote charging trucks because they weren't being used. https://insideevs.com/news/330686/aaa-charging-trucks-seldom-see-action/
