		<description><![CDATA[&quot;Mentour Pilot&quot; youtube channel &lt;a href=&quot;https://www.youtube.com/watch?v=VqF55MjU9jc&quot;&gt;tried out&lt;/a&gt; the  Pipistrel Velis Electro at Green Flight Academy in Skellefteå, Sweden. Summary: Good for training flights &lt;1 hour. Very short range, have to stay near the airport. It helps the airport is located near a cheap source of electricity. The electricity cost is negligible (about €1/hour), the bulk of the cost comes from the battery: €22,000 for 500 hours. So running cost is about €45/hour, which is very good.]]></description>

		<description><![CDATA[“But why are electric airplanes cheaper to fly? For the same reason that electric cars are cheaper to drive. Electric drive trains are vastly more efficient than ones that burn fuel. While the 50% efficiency of modern jet engines is amazing and modern gas turbine aviation engines see that efficiency at optimal speeds, battery electric aviation drive trains are 95% efficient. Further, they are 95% efficient or more when rolling around on runways or sitting still.”

Someone mainlined the EV Kool-Aid there.]]></description>

		<description><![CDATA[An electric battery will have 10 times the volume and 10 times the weight of the fuel it replaces. I find it hard to believe an all electric system can replace a fossil fuel system.

The other point is battery life. EV batteries are warranted for only 100,000 miles or 8 years, after which they must be replaced at costs ranging from $10,000 to $30,000, which means the EV has 0 resale value.

Batteries also lose charge capacity. An EV battery at end of warranty will hold only 70% of its original charge.

Then there is the fire issue. NYC&#039;s fire department recently noted that electric scooter battery fires are now a major safety issue and a major cause of fires in the city, over 100 so far this year. The scooter batteries have to be brought into apartments for recharging, and the fires frequently cause injury and even death.

The safe assumption is that whatever an environmentalist tells you is a lie.]]></description>

		<description><![CDATA[&quot;Urban air mobility&quot; is doomed to fail, and deserves to.

Why won&#039;t the U.N. Green New Dealer freakazoid contingent work to bring personal autogyros to the American mass instead?

Perhaps because the American mass is now deep, deep down into the physiognomical death spiral due to the quote-unquote thought leaders&#039; own catastrophic quality-control failure and sabotage?

I know how to fix it; I know how to pull back from the brink. Deep down, everyone knows.]]></description>

		<description><![CDATA[“Autopilots have been able to land and takeoff for a long time and big jets frequently use it, especially in low wind, low visibility circumstances…”

Yeah, the low wind part is important. Trying to land a plane in a heavy crosswind is a bitch. That&#039;s a major barrier to getting a pilot license. It was for me, for sure! If crosswind landings get safely automated, it will open flying to a lot more people.]]></description>
