"Trump Destroyed the EV Industry, Just When We Need it Most”
And Mark Carney and Doug Ford just went along for the ride.
I “filled" my EV yesterday (200km) for $8.
This is the same price as it would have been a month ago.
This is not a brag. This is a statement of fact and a call to action.

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.”

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.

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!!

Alternate Headline: “Trans Mountain doubles exports in 2025 resulting in 82 million tonnes of CO2 to atmosphere.”
The news dutifully omits the CO2 impact so here's the math:
There is 2.79 tonnes of CO2 in 1 tonne of average crude oil.
2025 exports: 24.4 million tonnes
= 68 million tonnes of CO2
Oh, but that's not all!
Alberta oil emits about 85kg of CO2 for every barrel of oil produced.
24.4 million tonnes of crude is 176 million barrels
Another 14 million tonnes of CO2!
Yay Canada!
🔥🔥🔥🔥🔥

A little dated, (2019) but still an excellent article/study here of global oil supply flows and uses. Informative for perspective on events during the #IranUSAIsraelWar
Charts show flows of crude oil, flows of natural gas, and use by industry of the same.
12-17% of crude oil and natural gas is used for “non-energy” process. (ie. not for burning directly). The other 88-83% is burned. #CO2
