But consider a timed out C206-scale electric aircraft, with only 40% left in its batteries. Enough for perhaps two climbs to altitude before recharging. If they could get it for the same cost as a gas C206 - AND not have to pay for gas - that's going to make the dollar signs light up in even the cheapest DZO's eyes.

Maybe when lighter than aircraft are hoisting charging stations to 14K, I reckon. But the big problem is that, and I get my news only from reputable sources like here, Electric Vehicles never wear out except the batteries and they're only 20% of the cost per vehicle. Also, just like there is no market for used gas tanks we can expect those batteries to just pile up, too. Quote Share this post Link to post Share on other sites

When I first started buying used Caravans in the early 90's banks would lend on the airframe/engine values and the expected 5% annual appreciation, there was even a chart. First time I sat down I had every t crossed and i dotted in my financials. he took a quick look and went right to the spec sheet of the airplane.

Cessna lists an appreciation schedule in its owners manual/ service manual? W/O derailing the thread. The most brilliant auto engineer IMO just laid out a Dark Matter Raxial Flux 6-phase E-motor of 800 hp, 922 ft lb of torque, that weighs 39 kg.(86 lbs). Which is 246 lbs less than the 800 hp PT-6-140 Blackhawk engine. Pictured below is its older cousin which develops 335 hp and is pictured besides a 330 ml energy drink. Soon to be installed on C-182 aircraft to put out of business climate doubters like BH. Edited December 13, 2023 by Phil1111 Quote Share this post Link to post Share on other sites

At the time if you could put 20% down they considered it a no brainer. Quote Share this post Link to post Share on other sites

theplummeter 15 #14 December 14, 2023 I haven't kept up much with this technology but am wondering if a reliable means of controlling prop blade angle exists absent oil pressure. I've always thought that electric airplanes with a changeable battery pack would work well for skydiving given a single base of operations and the short flights.

Better batteries, 100% efficiency solar everything, or maybe some kid sorts out how to tap into the planets electric field with an app. However it is coming and all to the Luddites chagrin. 4 Quote Share this post Link to post Share on other sites

I'm thinking 20 years to the STC. No more hot starts, hot section inspections, etc. Those electric motors have one moving part so just prop and governor overhauls. Full power to 18.5. They will put wind tunnels out of business. Edited December 14, 2023 by Phil1111 Quote Share this post Link to post Share on other sites

You're asking why they're not using wind and solar to build the equipment to build out the infrastructure for wind and solar? Again, Brent makes the case that wind and solar aren't here to support 100% of our energy needs right out of the gate and so they're not viable options. And again I'll ask: did you keep the receipt for that MBA? 1 Quote Share this post Link to post Share on other sites

The host nation throws a big party, bureaucrats, politicians and hangers on fly in on their private jets, make lots of pronouncements, make empty promises and check their calendar for the next big party.

That's the energy equivalent of 45 new nuclear power plants. Wind is similar. They added 110 gigawatts of wind in 2022, and are on track to do the same for this year. Compare that to 95 gigawatts of new coal capability under construction in 2023. Quote Share this post Link to post Share on other sites
