Relevant to today's hand-wringing about jet fuel costs:
I was trolling around looking for an update on Harbour Air's eBeaver project (electric conversion for their DHC-2 "Beaver" commercial/passenger fleet) and the latest I have found and most comprehensive on the state of development is here.
Looks like they're continuing to invest and progress. They first flew in 2019 but the pandemic made a big dent but the regulatory certification sounds like it has been difficult and the parts (motor and battery) have had to evolve, but they are still working on it and now are converting a 2nd plane with upgraded specs and are targeting 2027 for commercial readiness!

I had been following this pretty closely, but it has fallen off my radar. Thx for digging into it again!
I still think dirigible travel with solar skin has a viable business plan for transoceanic leisure travel.

@kboyd I have a lot of confidence in HA. They have been very determined and have been working consistently. I think they (rightly) see that given their clientele, it would be an extremely popular option if they had zero-carbon flights on their routes between VI and the mainland. And it looks like they want to leverage their knowledge to enable other conversions as well.

@chris This is awesome. As battery tech improves (more kWh per kilo and per litre) range and performance will increase. But someone has to be a pioneer and I'm glad it's a local company. I used fly HA between Victoria and Vancouver for work and always thought of them as a first rate company.
@tobiaspatton they are really great. I was so excited for their first flight back in 2019 that I very nearly went to the show myself. But settled for the youtube/twitter livestream.

@chris all true. The efforts that faltered were from the other side of the industry...

@mediocratese @Amgine oh that would be a slightly terrifying and awesome way to fly!

also found this excellent article about the motor developer, MagniX. It has some great technical info, delving into just how much more efficient the electric motors are compared to the piston and turboprop engines that they are replacing.
“a single magni500 Electric Propulsion Unit [the engine, inverter and cables], which weighs 185 kg… produces up to 560 kW. By comparison, the Pratt & Whitney R-985 Wasp Junior SB engine replaced in the eBeaver weighed 290 kg (not including oil) and produced just 300 kW.”

@chris Thanks for theresearch. I had been wonderding what happened to the project. I had seed videos of other efforts and always commented on Harbour Air being the actual first, but lack of news made me think that the stunt wasn't viable and abandonned.

the engineering article about the motors is super in depth, some of it way over my head, but they also compare the development of EV cars to planes and I get this... at least now... because it didn't occur to me:
Regeneration is great for cars!
Regeneration is a BIG NO for airplanes! Because if you glide and the propeller to regenerate power, you fall out of the sky.
so ya, none of that!
"Critically, one area the company worked hard on reducing was regeneration. At no point during flight, as well as descent, can the plane simply carry on under its own momentum while air drives the propellers to generate current. That would create a large amount of drag, and the plane would start to fall rapidly.
“Maybe a glider or UAV could do that, but not a passenger aircraft,” Armesmith says. “There are rules against it in aerospace, so we have to actively stop regeneration from being possible, it’s a fault we have to arrest,” Armesmith says.
“So, if we’ve either lost power or had to turn the motor off for any reason, the propeller needs to be able to windmill freely. We can’t have any electromagnetic resistance to the propeller free-turning owing to regeneration back into the DC bus.”
ya... glide good! fall bad! lol
I am very glad these very smart people are making it happen and a local company is right in there!!

@chris The explanation for the silence in Harbour Air electrification:
"programme despite a setback, revealed in 2023, that requires it to use Magni650s instead of less-powerful Magni350s."My guess is that the test flight worked with single occupant, but wouldn't with passengers on board.

@jfmezei ya one the other articles said it had to do with both power and redundancy as the higher power motor also uses 4 inverters, each powering a section of the motor, so if one fails the motor can continue just at a lower power.

Russia built rather a number of models studying ground effect planes. They are now producing them commercially to replace ferries.
All of the modern ones I have seen photos of have extremely short wings.

@Amgine that would be sooo cool!
There was a video a few years ago of a semi-dirig being marketed to extremely wealthy people. And a couple things stand out in my memories. The whole thing was electric - you do not need a lot of thrust if you are not overcoming gravity.
The second was 'sailing': the Zeppelins mostly used wind for their transatlantic flight speed.
But most important was the silence. They cranked the mic gain so you could hear the wind outside. The guy's breathing was louder.

@Amgine i would so love to try that out!!

Forgot to share this article from last summer, so about 4 months after the article you linked:
I am looking for any news they got the magnix650 motor(s) at the end of 2025.

This is the latest info I have found about the Magni650 - published today. But nothing about shipping them to Vancouver…
