The first picture is of the current production model. That is what we have only in blue like one of the later pictures.
a cleaner world for everyone.
-If you use coal-fired power plants to produce the electricity, then all-electrics don’t even look that much better than a traditional vehicle in terms of greenhouse gases” (Wade, 2016)
-When the electric vehicles depend on coal they “are actually 17 percent to 27 percent worse than diesel or gas engines.” (Braun, 2013)
Car manufacturers spend a lot of time and money advertising the benefits of electric powered vehicles to consumers, but they are hiding the fact that the production of these batteries is potentially doing more harm than good. When considering incorporating lithium-ion batteries into projects, remember the production process and consider ways of minimizing environmental effects.
Effects of Mining Lithium
...The U.S Environmental Protection Agency (EPA) conducted a study on the materials and production of a lithium-ion battery. The study concluded that mining these chemicals can cause the following:
resource depletion
global warming
ecological toxicity (Kaiser, 2013)
Some chemicals used in lithium-ion battery production are very rare and exist in tiny quantities. Rare metals are mined in China by passing bags of dirt through several acid baths, leaving behind the rare materials. “Those rare earths amounted to 0.2 percent of what gets pull out of the ground. The other 99.8 percent-now contaminated with toxic chemicals-is dumped back into the environment” (Wade, 2016). Overall, almost every stage of the lithium mining process can lead to harmful environmental effects.
I wonder what the resale value of these cars are when they're tax payer subsidized to build and then heavily tax payer subsidized again to sell. What a great car! Wonder how Musk pulled it off so he can rake it in at both ends for a product that the market doesn't want.

DaveC said:"The facts are a Tesla is likely overall worse for the planet and worse for human beings vs a traditional car in terms of both greenhouse gasses and it's massively worse in terms of it's environmental impact and pollution. I studied how to evaluate similar technology by the guy who came up with the entire concept of EROEI, Energy Return On Energy Invested and wrote Thermodynamics textbooks. I understand not everyone has the same perspective and people don't have time to research every subject in the world, but be careful what beliefs you adapt. The concept of an electric car only works out if we have clean sources of electricity and better battery technology. It's a great concept that doesn't work with our current level of technology."
What is the resale value of high-end DACs? ...High-end turntables?
I get it guys. Some here don't like Tesla and/or electric cars in general. This thread is starting to turn into a digital vs. vinyl thread. No surprise there.
Except this isn't subjective. It's about FACTS, and it's totally objective. There's no possible way you can make a case for Teslas being better for the environment vs an average gas powered car.
Sure I can, no damn emissions. None. Once I put up the solar panels, the car has no carbon footprint. None.
Things aren't built in a vacuum, it takes energy to manufacture!

It takes energy to build any car. If I can charge my car via solar, it is better for the economy than any gas powered car.Things aren't built in a vacuum, it takes energy and resources to manufacture! There's also the life span of one these cars, you have to amortize that and the cost of manufacturing, installing and servicing these panels.

+1 and to add to your comment Tesla could be costing us in more ways that we even know. The way Tesla is subsidized it makes it very difficult or almost impossible for anyone with better technologies to compete, that could be a very huge loss.

Other cars aren't making any claims to saving the planet nor are the taxpayer subsidized or given special status on the roads with HOV lane usage. If it's really good then it should sell by itself, it's not as if there's a shortage of expensive cars in the marketplace that are competing very well even when we're getting gouged by all kinds of us taxes to make them more expensive. This is what I resent not the tech.
