This is "green energy at work".....

No, that’s propaganda at work. It’s like windmills using and spilling oil, the net result is still a major reduction in emissions and pollution. The suggestion green alternatives need to be produced using green alternatives is just childish.

The fossil carbon subsidy into this first layer of sustainable energy is the seed. Soon it will be practical to operate the manufacturing chain from ore (or scrap!) to product using that transitional first layer and its products as the energy source.

New battery technologies don't use lithium and those that do don't use much if any nickel or cobalt. New mining and refining techniques are reducing the impact of lithium mining on the enviorment. except for the battery you need about the same kinds of materials to build an ICE vehicle. Aluminum graphene and sodium are just a few of new emerging battery technologies and most of a Lion battery can be recycled. That might have been the BOM a couple of years ago, but new technologies will do away with battery cooling systems among other things. Even rare earth in magnets can be replaced by more powerful Niron magnets
EVs have far fewer parts than an ICE vehicle and some have the motors in the wheel hubs. There will be no cooling system, exhaust system, no fuel system and tank and with regenerative braking brake pads could last the life of the car. No oil, no gas, no transmission fluid and perhaps no brake fluid. Ya gotta look ahead, all the car companies are betting the farm for a reason on EVs, in a decade charge time might be less than 10 minutes and ranges could exceed 1000 miles per charge. Nobody will be selling ICE vehicles and gas stations will start to become scarce. On the flip side gas should become cheaper with reduced demand. I figure in America it will start with the second car used to drive from the burbs into the city to work, plug it in at night.

Current batteries will give ya about 20 minutes of flight time, the next generation will be 3 times better for an hour and a fast recharge time, the theoretical limits of a lithium sulpher battery for instance is 8 X a current Li-on. They figure they should get to at least 5 times the current capacity in a few years after some recent breakthroughs on several fronts. So say in a decade yer flying motorcycle can fly an hour and a half to two hours traveling at 60 MPH taking in the scenery for 100 miles. If it recharges in 5 minutes and charging points are plentiful, I can see trouble with people cross countrying and shotguns!

Here's why you should not GOSSIP.
In Ancient Greece, Socrates had a great reputation of wisdom. One day, someone came to find the great philosopher and said to him:
- Do you know what I just heard about your friend?
- A moment, replied Socrates. Before you tell me, I would like to test you the three sieves.
- The three sieves?
- Yes, continued Socrates. Before telling anything about the others, it's good to take the time to filter what you mean. I call it the test of the three sieves. The first sieve is the TRUTH. Have you checked if what you're going to tell me is true?
- No, I just heard it.
- Very good! So, you don't know if it's true. We continue with the second sieve, that of KINDNESS. What you want to tell me about my friend, is it good?
- Oh, no! On the contrary.
- So, questioned Socrates, you want to tell me bad things about him and you're not even sure they're true? Maybe you can still pass the test of the third sieve, that of UTILITY. Is it useful that I know what you're going to tell me about this friend?
- No, really.
- So, concluded Socrates, what you were going to tell me is neither true, nor good, nor useful. Why, then, did you want to tell me this?
"Gossip is a bad thing. In the beginning it may seem enjoyable and fun, but in the end, it fills our hearts with bitterness and poisons us, too!"

There are now 8 billion of us — but soon we'll hit a decline we'll never reverse
This week, the world's population ticks over a historic milestone. But in the next century, society will be reshaped dramatically — and soon we'll hit a decline we'll never reverse.

This is what my dad had done for the past 8 years for the CAF in Mesa AZ. He was the flight engineer for the "Maid in the Shade" (1941 built) B25 bomber and the B27 "Sentimental Journey"... there were prob passengers on board. They would fly the fleet from AZ to Edmonton Canada, to MS, to MO, and all over the US for airshows and sell seats for about $300 reg seat to $800 for a gunner seat. It was about a 40 min ride on these old warbirds. Very expensive to maintain them. The B25 would burn about 5 gallons of oil an hour.
Had the pleasure of seeing FIFI last year... the only operational B29A SuperFortress on the planet ... one other belongs to a private owner. (Doc) Being that this was in Dallas.. that's were FIFI's division is. Sad day for the CAF.
Dad loved the CAF... he was just getting too old to change out an engine on the hot tarmac ... when he passes, they have this program where you can go up and have your loved ones ashes dumped in a tissue package from the bomb bay doors. Im gonna do this, and spread his ashes in the AZ mountains.

I love the idea... I just don't think it's sustainable. We can only recourse so much.. and to replace millions of vehicles is just not possible compared to fossil fuel. Especially the commercial line of truckers, or UPS, FedEx.... etc. We will need FF for the next how every many years till we die.

It will take a decade or two, but it will be done.
Here is what Europe is doing and they are experimenting with a few of these systems for trucks. It uses a pantograph to charge the batteries on the move and say up hills. With new batteries they might only have to cover 30% of a main route or less and probably use the same rig to top up at truck stops, while there are truckers. One thing about electric drive, no gears to change instant torque and with self-driving trucks a driver might climb in the cab to take it into the city and its final destination. In Europe the companies like the idea because it saves money.
EVs depend on battery technology and availability and that is expanding rapidly with large factories spring up all over the place. EVs will be cheaper to produce and buy, maintain and operate than an ICE vehicle, that's why they will sell and the faster the charging times and the longer the range and life of the battery pack, the more they will sell. If your EV is charging at home and the power goes out it can power your home for days, just don't cook too many roasts in the oven.
A neat idea for electric trucks, used by trains and with GPS and computer control, useful for charging trucks on the move.

I guess we'll see...I got about another 20 years left in me (hopefully)... but tech in the next 10 years is going to be interesting. I just am going to need a EV tri-scotter that will hit 60 mph...then I'l be happy.
