How do you propose to advance that? Energy stored per pound has advanced a lot. If you don't believe that, take a look at the latest generation of cordless tools or laptop computers. Being able to store energy at a reasonable cost and weight is key to making electric vehicles practical. Although the Volt is not yet the ideal electric car, it is a step forward. Internal combustion engines started off slowly also. Take a look at the automotive engines of 100 years ago vs what we have today. |

The Tesla is quite the technological car though! === The Tesla is a fine example of what you can do if cost is no object. Since they are in a high end specialty market there is not a lot of pressure to lower the cost but it's nice to see an example of what is doable. |

Energy stored per pound has advanced a lot. If you don't believe that, take a look at the latest generation of cordless tools or laptop computers. I fly R/C. The advances in batteries (Li-Po and Li-Ion), and in the electric motors and their controllers, have enabled electric airplanes to be competetive performance-wise with their glow fuel powered counterparts. The downside is the need to re-charge after every flight, and the cost. You can buy a glow motor and a lot of fuel for the cost of a motor, controller, batteries, and special charger. |

I know all about charging and discharging cycles and issues. The materials may have improved but, the basic battery is still the same. You charge it, you discharge it, you charge it and the cycle keeps repeating until the battery wears out. |

It has a battery and electric motors. |
