My idea a long time ago is you use solar to charge your electric car. Thus, transportation using renewable energy, no fossil fuels. And what if the
whole world did that? You would be on your way to a sustainable world that doesn't go extinct. A better world.

Also, people would essentially have low-cost, free energy which would save people a fortune.

I hope Tesla takes this idea and runs with it.

Well, Anonymous (a resident of Another Mountain View Neighborhood), Robert Heinlein also proposed more or less the same idea (in impressive technical detail), in a famous story around 70 years ago. In a wave of subsequent popular stories, the same author took for granted solar electric power as having replaced fossil fuels. So the ideas seem to've been around for a while.

Very often in technology, the issue isn't the abstract vision (which many share), but how to implement it in practical, manufacturable, affordable detail. The devil being in the details, as they say. . .

@Anonymous, this is exactly what they're doing. Using solar panels, you charge a battery in your car or on your garage wall during the day then use that power to commute or run your home at night.

A lot of cynics talk about the storage problem with solar, because industrial-scale batteries don't exist to absorb the excess power from an industrial-scale solar farm on the sunniest days. What may turn out to solve this problem is using distributed solar panels and batteries on rooftops and in each corresponding garage instead.

One company that doesn't make any money buying another company that doesn't make any money mmm.

Let's say everyone in the world was using solar and Tesla was getting a percentage of the money from solar. You don't think they would be making money? It is a long-term vision.

Yes, it really doesn't matter whose idea it is. My point is to get the
idea in the hands of the masses. Democratize the idea where everybody
knows it. And it looks like they are already doing that.

Me thinks Elon Musk is desperately rearranging the financial deck chairs on his twin Titanics, or is one the Lusitania? Admittedly, as a sadder and far wiser former senior dot.com startup employee, I view Tesla as a huge "pump and dump" Ponzi scheme --- my highly enlightened opinion, of course --- having been personally caught up in the collapse of the huge dot.com and telcon pump and dump bubbles.

For 2015, I recall that Tesla reported losses of about $900 million on sales and revenues of only $4 billion. Even worse, a significant fraction of its revenues were/are from advance "deposits" extracted from wannabe customers for future deliveries of promised vehicles. IMHO, "borrowing against the future to cover present negative cash flow" is a better term than "deposits". Too bad that more people don't understand this.

Also, huge Tesla losses loom into the foreseeable future --- Model X sales are limited due to serious manufacturing problems and delays, and also a huge sticker price increase 50%(?) above that promised to depositors. Even worse, Musk's projected 2017 schedule for production and delivery of his Model 3 is wildly and recklessly unrealistic, at the very least. Again, all of this paragraph my highly informed opinion.

IMHO I can't wish Tesla good luck because I think Musk is lying through his teeth, either due to desperation or due to megalomania, most likely both.
