You can't but truly admire Elon Musk and his staff at Tesla for what they have achieved so far and express every confidence in them resolving these challenges.

Switching the fuel has been on the research agenda since the 1950es but it is still very difficult, in spite of millions of people dying from the health issues associated with auto carbon exhaust every year.

Tesla is like an Apple, but in a sedate traditional industry that is full of roadblocks to development.

Wishing Tesla the best of luck!
