The combination of cars and expanding population completely changed the face of the planet in a very short period. Everything is built around providing space for cars and everything that is around them. The scene in this movie https://en.wikipedia.org/wiki/Les_Visiteurs when they see a modern road for the first time is actually quite telling.
The beauty of electric vehicles is that the energy powering them can come from many different sources. Worst case, fossil fuel can be used to charge your batteries. But wind and solar, hydroelectric, hydrogen, biomass and methane are all usable for electric cars in one way or another with varying efficiency. The big problem currently is energy storage. Far better batteries with far better life spans will be needed. $10K to swap out a defunct battery pack is just too expensive.Denian Arcoleo wrote: ↑Sun Dec 03, 2017 1:41 pmElectric cars are most definitely a good thing and will, I'm sure, be on our streets fairly soon in big numbers. Personally I can't wait, mainly because of the improvement in urban air quality that will come with them. I have always felt that the internal combustion engine was one of the worst inventions ever devised; a fume-belching monster that destroys the environment.
The traditional car companies are working hard for this to happen. The new entrants are trying to change it so that the car will go off and pick up somebody else and then somebody else … until it is time to charge the battery at the point where it optimizes the life of the battery. A different car will pick you up. This ownership change is the "challenge" for the traditional manufacturers but the the real benefit from an environmental perspective.
This is not as straight forward as one might think. The most ecological method is to charge slowly during non-peak grid usage. This means that the power company will not have to provide gigantic peak capacity - doing so is very UN ecological. Furthermore, rapid charging is highly inefficient. So there is considerably less time available for driving passengers to and fro if duration of charging stays very ecological at 8-12 hours and/or during daylight hours in conjunction with solar arrays. At least, with current technology.simonm wrote: ↑Tue Dec 05, 2017 9:08 pmThe traditional car companies are working hard for this to happen.

No quibbles with that. As far as I have always understood one of the initial reasons for pushing street lighting at night was so that the electric companies could dump excess base load at night. How wonderful it would be to regain the night sky by dumping the load into cars.
Hm, it appears to be 80,000 lb fully loaded (grabbed that from the website). Not sure if that's conventional ... but the number's impressive at least!
The classic "standard" heavy truck in Europe is 40 tons (Ignoring long ton, short ton and metric tonne). There is a bit of variation. So the 80,000 is pretty much an international standard size. That gives you 20,000lbs for the truck and 60,000lbs for a standard 40ft international shipping container.
Well a very similar feature has existed for a long. You hire a person called a chauffeur to drive the car. And many countries have a variation called a taxi or sometimes limousine.
5-10 days of having no aircraft in the air would likely make a major contribution to clean air in terms of greenhouse gas effects at any rate. Ditto, keeping the top 50 biggest ships from traveling for 2 weeks. I am back to seeing some of the gorgeous multicolored sunsets of my childhood. Back then it was due to coal smoke for heating, now it is due to the exhaust trails (aka con-trails or chem-trails ) from aircraft. Same bright orange and lemon colors. But the air travel and sea shipping industries have major lobbies whereas private car drivers do not.
