Yes i have been following Tesla for some time. This is the new "Gold Rush" era. Whoever can come up with an alternative fuel, enviromentally friendly car will be rich....Hydrogen is just about the most enviromentally friendly that there is. Of course electricity is not as clean as most will think. Half of all electricity in this country comes from Coal. 70% of coals energy is wasted just trying to harness the energy in it.
The sun is our best bet for electricity. Or wind.
Buy stock in Tesla. You won't be sorry. It will be the next Ford or GM. The technology won't go away. The guys that started Google own the company. They have more money then god so Big Oil can't buy their product and bury it.
