Very cool stuff. Electric plane seats 19, travels 250 miles with no emissions.

Mile high club says otherwise.

What if it's so quiet people can hear farts in the cabin? Isn't farting with impunity the real perk of air travel?

Electric puddle jumpers.  

Probably a hedge on rising fuel pricing for quick trips.

The ES-19 could hit the market as early as 2026.

This is exactly what big car companies used to do with All Electric Vehicles before Tesla came along.  They dump a little money into some interesting startup, sign a meaningless, non-binding 'deal' for some number of units, and they get great press out of it and it makes it seem like they care... and then they continue business as usual. 

In this case Heart Aerospace seem to only have just received $35Million in Series A funding.

Heart has made a full-scale prototype of its electric propulsion system, the core of its technical innovation. But the company still has to complete many steps along the way to its proposed date of commercial operations. Chief amongst these is actually assembling a prototype of the full aircraft, testing it and getting it certified with relevant authorities in the U.S. and Europe.

I'll make a not-so-bold-prediction that this will not fly in 2026 and United will never receive any planes.

I can see it now.  

Ladies and Gentlemen I apologize for the delay, we have had lots of ground traffic during our taxi to the runway and have used a good deal of our battery power on the ground.  We are currently 25th in line for takeoff so we are going to head back to the gate to charge the batteries so we can actually make it to our destination.  We will set a new departure time of 8-10 hours from now.  Please remain in your seats during recharging.

Like the Boom supersonic jet I think Kirby really likes a PR stunt. Minimal investment by the company for some good press, but a 250nm range? Air shuttle, NY approach, say when ready to copy holding instructions.

With apologies to Ron White, that sounds like just enough range to get to the crash site.

I think we are a couple of generations of battery and motor technology away from being able to make an electric airplane a commercially viable product.

And the electricity required to charge this plane's batteries comes from a plant powered by what sort of magical source?

I’m surprised the air force hasnt developed a micro nuke plant for a plane that can fly indefinitely during a nuclear war.

Not saying they don't, but door-to-door in most cases it's a waste of time.

This is definitely an empty contract. But the answer to your question if these planes were to end up being real is a power grid that, even if it were entirely natural gas based, would still be more carbon efficient than a typical plane engine. Scale matters when you're working for efficiency.

When I was flying a lot for work at my old job, our informal rule of thumb was genrtslly to fly if driving would take more than 3 hours. Part of the reason was that was about the threshold for actually saving time and also to make sure we wouldn't be too tired from the drive for meetings/giving presentations.

Dallas-Houston is borderline IMO; Houston-Austin is drive all the way. And now they have those ritzy buses like Vonlane that's another option -- maybe the best, depending on where you need to be.

I flew Dallas to Houston fairly frequently a few years ago. The Hobby-Love connection could definitely be done in under two hours of total travel time (door-to-door), making it much better than the drive, particularly if it was a day trip. I did drive more often if I didn't have something early and planned on being there multiple days.

Why, the plane’s propellors provide the constantly renewable energy of course!

It is easier for us to drive down to SPI from Round Rock than it is to fly from ABIA to Harlingen, then get a rent car to complete the trip. It takes a couple of hours longer, but there’s no airport hassle and having to sit next to some asshole (except my wife still has to).

Electric jet airliners

oooooh electric jet airliners

driving’s faster anyway

Lost in all this craze is the fact that new geared turbofan models of the 737 and 320 burn a gallon a minute less fuel than their predecessors. 

I would think the logical intermediate step between them and electric planes would be something like having an APU provide power to two electric motors with battery back up like a diesel electric locomotive. Or have the apu top off the batteries as needed. 

They're obviously still  a few leaps in technology away from practical emission free travel. 

BTW, the navy did patent small fusion reactors recently. That would be a start if it ever reached fruition and battery and other electric tech took another step forward with stuff like graphene etc..

What would be the point of that? If the power is still coming from combustion, it doesn't seem like you're gaining anything unless planes can also take advantage of regenerative braking in some form. 

At any rate, we are a ways off from electric planes being practical, mainly due to energy storage limitations. Current battery isn't great for that purpose. Conceivably hydrogen and its higher energy density could better suited for planes. When it does become a reality, I think the big advantages are making planes mechanically more simple and removing combustion entirely from the pressured tube thousands of feet in the sky.

So I'm not allowed to have a Li-Ion battery the size of a deck of cards in my checked luggage due to risk of fire, but this bird is going to be powered by a giant bank of them...presumably in the hold? Okay...

Both we and the Soviets experimented with this back during the 1950s. Abandoned as impractical for lots of reasons, not least the issue of what happens if one crashes. A submarine or aircraft carrier sinks into the ocean, it doesn’t rain fallout on what would most likely be your own territory or an ally’s.

ICBMs, especially submarine based and better early warning made the whole concept irrelevant. The issue was always survivability for a second strike…not the need to operate indefinitely. Any nuclear war between the big boys will be SHORT.

Here are the official travel method guidelines by trip length (that I made up just now):

0-2 miles: walk, fatass

2-20 miles: public transport, if available (disregard south of mason-Dixon); otherwise, drive

20-120 miles: drive

120-300 miles: bus/rail, if available; otherwise, drive

300+ miles: fly

This. Besides contaminating everything behind you, it's ridiculously easy to track.

Should we now google the apocalyptic lithium and cobalt mines, many being mined by children and workers sold into slavery.  These batteries are not without a cost....often a heartbreaking one

Major manufacturers are either moving on from cobalt entirely or are re-sourcing their cobalt from better run mines. The problem is primarily with the Democratic Republic of Congo, which controls half the world's reserves of cobalt.  I'm not aware of the same allegations regarding lithium mining, which is much wider spread. Regardless, the US actually has huge reserves of lithium (#4 in the world). I know Tesla is looking to start sourcing its lithium from Nevada for instance.

Asked and answered.  "Better run mines" on paper sounds nice.  At first these Congolese mines were sold as "humane" and "better run" to get major corporations to entertain them.  As demand rises, and scarcity sets in, these mines will be revisited.  If not us, China and other countries won't bat an eye. 

The point being these batteries are not without a physical and human cost and leave massive scars in the landscape that will never recover (in our lifetime).  The brackish, contaminated water to the tune of hundreds of thousands of gallons per metric ton.  Not sure when NV is going to get 500,00+ tons of water per metric ton of lithium, even with it's reserves.  EPA will have a field day with them, hence the dependence on foreign mines.

That's why I said most companies were transitioning away from cobalt entirely for batteries. It isn't a necessary component and can be replaced.  e.g.,

You could literally say this about pretty much anything done to gather resources for our modern life. I'm sure you have the same concerns about ground water contamination associated with fracking or the mining of other metals. The solution isn't to abandon development entirely, but rather to improve our processes to lessen human and environmental damage.
