The electric powered seaplane in the story needs to be certified to carry passengers but that will happen long before 10 years.
The passenger service anticipated for this plane is short (30 minute) flights in the lower B.C. mainland. Btw, the plane is owned by an existing seaplane service and has be extensively modified for electric flight; I don't think the company would interested in maintaining a demo model, not making money, for ten years.


Incidentally, the federal throne speech last Thursday had a sentence saying "the government would be it easier for Canadians to buy emissions-free cars".....I can see the government giving financial incentives for full sized electric flight.

Evidence of change north of Toronto... one of the York Region forest tracts - Hollidge -received upgraded visitor infrastructure in the last year, one of which were a couple of electric charging stations in the public parking area.

What negative comments? I was pointing out the fact that they didn't mention that model aircraft have been using electron power for over fifteen years. That was an interesteting omission.

As for electric flight that is nothing new. Heck, even flite test built an man-carrying electric foamy and yes, it DID use Hobby King batteries .

Now **THAT** is a noteworthy achievement!

Re: Full Size Electric flight

As usual , people read into a statement what they want to read . All I said was (jokingly) that HK batteries not used.... . Ok , back to the future and my original post . The reference to power source was that Harbour used lithium-ion batteries similar to the ones on the space station because of previous testing done and high approval rating even though they do not provide the power to weight of other lithium based battery sources .

The whole electric power source will advance battery technology for commercial use and THAT will eventually filter down to our hobby.

The impact is reaching around the world and less than 18 hrs after the initial flight.

Re: Full Size Electric flight

Thats my bad, 10 years to a new aircraft, 2 for commercial use. That makes much more sense now that im thinking about it

Re: Full Size Electric flight

I think its neat. Was it a Canada first? I wonder how hot the power cables got. When Commercial jets started flying with Lion batteries they got grounded because of fires. I never read where but I can assume the batteries and cables caught fire from the heat generated. Cheers Floyd

Re: Full Size Electric flight

There have been other converted commercial built aircraft that have flown on electrics
previously designed to run on a fueled power plant. And definitely never one on floats so this is as far as we know it; is a first for Canada or even in the world. The electric power plant ( am sure someone will try to correct it) was built in Seattle ( more specifically, Redmond) by a company whose head office is in Australia but owned by an Singapore investment company. How is that for a combination ? The system had previously been well run and tested before installation
in the Harbour Air Beaver.

There have been many pure electric aircraft that were specifically designed to fly on electrics before but not an all aluminum aircraft like this.

Re: Full Size Electric flight

Although very cool I still don’t see the environmental reasoning behind electric airplanes, motorcycles, or vehicles for that matter. Until batteries can be produced in a more environmentally friendly way (and last longer and be recycled), and the electricity to charge them is produced/delivered in an environmentally neutral way...what have we gained? From what I’ve read it’s questionable if any of our current electric technology is going to be any better for the environment once everything is taken into account.

To date, electricity hasn’t done anything to improve the environment. It has actually caused more harm than oil products. It’s nice to pretend to help the environment by going electric.. but I don’t think it’ll be a better alternative to oil in my lifetime.

Re: Full Size Electric flight

The maintenance on brushless is very low in comparison to IC engines and more so on aircraft engines. A year or so ago someone did a more realistic comparison between electric vs fuel vehicles and the fuelled power came out on top by a slight margin . They took into account the initial investment on comparable sized/ features car , cost of replacing batteries and so on.
It’s like diesel vs gas vehicles . Sure ,the mileage may be better on diesel but the maintenance cost is higher , initial investment is higher , cost if fuel may be higher and so on. Gotta look at the big picture. Pros and cons with each.
