1st electric seaplane flight

Recommended Posts

That's 3 short minutes for a pilot; 3 long minutes for a Beaver.

Poor raped Beaver. And the loss of the great radial sound. Couldn't they have used a modern toy like the Icon, where this mod doesn't hurt?

The potential for low noise flying is huge, glad this test flight went without a hitch.  Save the environment for future generations too.

Cheers, Rob.

Well, I have lived in interesting times. And I never thought a DHC-2 could have been made totally electric. It`s gonna need more power obviously. More power had been one of the reasons why the Beaver was/is great. I'm in Northern Canada; where Beavers are still doing what they were designed to do. They honor their designers, their pilots, the mechanics that keep 'em flying, the passengers and operators who trust them. The dust of WW2 was still settling when the Beaver was being developed and I still can't find the right words to describe it's greatness.

Now that's cool! I agree: the old engines and all that will be missed, but seeing the de Havilland Beaver and eventually other aircraft, which were originally designed almost ages ago, to continue flying in the future with state of the art engines by then, is something that makes me a very happy camper too!

Enjoy flying and happy landings.

Well, you need a massively overbuilt and strong airframe to carry one ton of batteries, yeah? 😉

I read elsewhere that the motor is tiny, the size of half a beer keg. Consider that weight savings in the engine, plus no fuel tanks in the wings, no fuel pumps.

It's still probably overweight compared to a stock Beaver with all those batteries, but it might be practical for what they're aiming for -- basically a demo flight from Vancouver BC to Victoria BC and back. After a battery charge or replacing the battery pack.

The electric motor they used was actually de-rated to produce the same horsepower as the original engine. In the long run they are looking to use the same engine at full power in their Otters. This article gives more technical details than most of the others I have seen.

One of the biggest challenges is getting battery weight down and power up.

Batteries are big business and the race is on ... I recall watching a show on some prototype batteries that were very efficient and you can actually cut them up and they don't explode and even more impressive will continued to provide energy even when sliced up.  Reduces an aircraft's bomb potential for terrorist ... 777 is what about 149 tons of fuel ... DCH-2 about 1.05 ton of fuel?

And an environmental disaster. There are already a few documentaries about the still little known large impact on nature, animals etc.

True. But in all fairness: literally all fossile fuels are an environmental desaster too. In the end the source with the lesser impact on the environment should be preferred i think. And the development of batteries is still early stages here so i remain confident that there is lots of potential for optimising still to be discovered. But sure, also lots of lessons yet need to be learned before a real sustainable and convincing solution will be on the table. But at least it seems to be heading in a good direction.

TBH I'm not very impressed, electric motors are relatively straight forward. The difficulty is storing the electricity, I'd be interested to know what payload and range/endurance are, I'm willing to bet if you want to fly the thing for a couple of hours you'd have to fill it entirely with batteries. Gonna take more than 3 minutes to transform the industry, I wouldn't even call this a start.

Only if you don't dispose of the batteries in correct methods ... most local electronics stores have battery drop points and 90% of batteries are recyclable... so you're ok with if people dump used car oil down the drain rather than taking it to a recycle center? ... and then we have the oil spills, drilling, etc. etc. ... I can go on and on and on about how much worse oil is for humans but sadly it will get flagged as "political" regardless of the science involved and viable sources of cleaner, cheaper, an easier alternative energy.

The aircraft flew, it's a start ... how do you think humans made it to the moon if they didn't start somewhere?  You can take your same logic and say this wasn't a start:

uc?id=1UwS0tzyiJlq-2DNPOkPT1QpG_JYvnqSB

a whopping 852 feet flight ... and yet here we are today:

uc?id=1KIJluSkP0Es0IpcQ9Zkneedg0Sf-o8hy

Thankfully people do think outside the box, that's how progress happens.  BTW, 81 hours is the longest all electric all solar powered flight.  Longest battery powered 9 passenger aircraft flight is about 564 nautical miles and that will likely increase to over 1000 nm in the near future as battery technology evolves just like oil based combustion engines evolved over 100+ years of R&D.

Cheers, Rob.

Cutting co2 emissions to pre-industrial level? Dream on... At some point the harsh reality will dictate the only possible course of action, i.e. adaptation.

I'm talking of the little know fact about the environmental problems when producing large batteries for cars etc.  That's a drama that just starts to unfold since the production rates are still very low.

Concerning disposal; A few month ago the first Tesla crash happened in Austria with a totally destroyed Tesla and it took the owner of the car seven weeks to find a company which can handle/dispose the battery correctly. In the meantime the car had to be placed in a special container because no one knows if or when the battery ignites.

As Murmur mentioned, the co2 problem is way bigger than many of us dare to assume.

Btw, powered flight started with Gustave Whitehead, not the Wright brothers 😉
