This is the first opportunity I've come across for a random person to ride in a 100% electric airplane. $250 for a "trial introductory flight". It's in Australia but appears to be available to anyone.

I'm a little confused. It uses solar panels to charge a battery right?
And the battery charges the EV?

Exacty. Many off-grid people could make this (buy panels, buy a battery, buy an inverter, install the panels, etc.), but this system comes in one piece ready to charge. No need to install panels, no need for wiring, no permit, no nothing. Everything is in one piece, dropped in your driveway and bam, you can run your car forever and have this move with you whenever you change house. It catches enough sun each day for 2 average commutes. And it's rated for 125 mph winds I think.

I'm thinking that if you live in a condo or apartment and have assigned parking , maybe you could get association approval and move it into your parking space. Assuming you don't have covered parking, of course. Would solve the problem of charging an EV for apartment dwellers.
 
Ive never been a huge fan of large capacity batteries… more like i dont like the prospect of them being almost utilized everywhere… trucks….rigs…cars…trains…planes…houses…ect… At the end of the day this idea isnt fully developed yet and has a long way to go before we decide to throw it as a reliable source of “energy” to use in every day uses. I think one thing that differs batteries from fossil fuels is one that fossil fuels store without depleting its own stored energy. They are a Weight friendly, think about aircraft loads, most of it comes from burning fuel weight… as per a lot of other vehicles…I dont necessarily think batteries are bad but they are indeed a long way from being a reliable and efficient fuel source that can be used. Im not the best when it comes to this subject either because a lot can be said about both sides but at the moment one industry makes batteries more than they are actually efficient, economical and reliable… so at the moment canceling fossil fuels with no real practical impact, is a lie because most people dont know that the world practically runs on it and you can never really be carbon free, or even make “free” energy because as The Laws of Conservation of Energy… “energy cannot be created or destroyed, only transformed from one form to another.”

And that is exactly what electricity comes from (most of it) and the labor to create the batteries consume fossil fuel as well… at this point it requires more fossil fuels to make, transport, charge, and maintain batteries and electricity than the product actually gives back energy…

What I can say is that batteries are now sufficiently dense in energy to make really cool, interesting and useful products that weren’t imaginable only 20 years ago. So I’m looking forward to see what will come up next! ⚡ Never I would have thought battery cars could be as good and better than those I learned to drive in and only 5 years ago I didn’t think a battery could power a manned aircraft, but here we are. Very exciting times!

Lots of assumptions and just plain wrong ideas here. There’s posts addressing all of this between this thread and “ICEs and EVs”. I’m sorry you’re not a fan of large capacity batteries though, lmao.

"High Voltage: Tesla’s supersized Gigafactory could need 2 lithium, 4 cobalt, 8 nickel, and 9 graphite mines’ worth of production every year
Tesla's Gigafactory needs 115,000t lithium, 15,000t cobalt, 14,000t manganese, 125,000t nickel and 170,000t graphite anode pa."

That's a lot.

Yes, it is.

In my local area, they cut down forest after forest to put up solar panels. That cannot be good for the environment. Now, we gotta mine more.

I agree - it's an environmental disaster.

This what our 'green' EVs are costing us.

Serious question, is drilling for fossil fuels any better? How about extracting ore for metals? Fracking seems pretty terrible too. Plastics production?

Seems like most anything we do craps on the planet… no? Why no outrage for any of these other issues? Sure does appear that to have all the niceties of a technologically advanced society we end up destroying the Earth. Maybe we’ll figure it out some day…

Mining is bad, but we need it with our current technology for recycling.

Drilling is bad but we need it with our current technologies for transport and manufacturers.

Trust me, I’m outraged at what these raw material miners are doing.

I’ve said it before, but if the goal is to reduce CO2 output, EVs will help. Outside of this, do we just ride the dinosaur until we’re out of fossil fuels and then figure it out?

It’s all complex and I don’t know if there’s any obvious or easy solutions, but the politics of it all are going to be the biggest hurdle in anything we do from here on out. I’ve heard enough well off folks up here in Burlington brag about driving their Teslas and saving the environment all while they’re flying down to their vacation homes every weekend. I think things need to change but the “green” movement to a lot of people is more about clout than action. We’ve got a long way to go, whatever we do.
 
Tell me guys, do people go in housing forum threads and tell them how many trees they have to cut down to build houses? Steel for skyscrapers? Concrete for sidewalks? Silicon for chips? Diamonds for jewelry? Aluminum for aviation? Kerosene for jets? Rubber for tires? Come on now. I'm not the one saying EVs are "green", but if you care about that, and that is fine, know that by all measures they are more sustainable than many alternatives (but not more bicyles). In any case, it's irrelevant to this thread.

Now if you want me to start a thread on the pros and cons of mining and the use of natural resources in general, I can do that but singling out battery, and electric motor and vehicle production while ignoring every other industry would be a problem. People have been mining, it's a thing. Not new.
