re: Should we invest into tesla?

Today as prices are high for the average person but in theory if you're a man of means you can buy the new Tesla solar roof which looks incredible BTW for around $106,000 for my house, yes I got a quote, and then charge your tesla using your homes roof collecting energy from the sun. Is that feasible? No its not today, but remember when plasma tv's were $10k for a 60 inch and now they're $500? Technology always dips, of course we're never all gonna be on solar but its pretty remarkable that tesla just passed 4 billion miles logged in their cars, how many gallons of gas were saved there?

How many gallons are they saving kauai annually with their new wind farm?

Im in the gas business and I can see the benefits, but obviously the costs aren't feasible for the mass market today to add a $100k roof + a $100k car to save the planet. Plus I live in a state, Texas, thats still a tad backwards where I have solar panels but I can only have enough to cut 80% of my bill but due to regulations, 20% of my energy must still come from the grid so I could never be totally off the grid. Either way the panels from the same company, solar city, were much cheaper than the roof, but the roof looks so good that I would consider doing it if i hadn't just installed solar a year ago.

Also a large misconception is battery life, the p100d, a buddy of mine has one it can do about 500 miles on a charge bc of how the battery actually charges at low speeds driving around the city
