I really hope that Tesla can actually become a profitable company, because it's time we had some real innovation in terms of car technology. I'm not a car buff or an environmental buff, but having a real zero-emissions car that will help get rid of our dependence on oil just makes sense. However, can any experts educate me on the status of the Li-ion battery? My understanding is that Li-ion batteries lose 30% of their capacity over 2-3 years. So what does that mean for the range of the Tesla cars? My Honda Accord lasted 11 years and 200k miles, it doesn't sound like Teslas have nearly the same durability and range. Is this a ticking time bomb, or is there a solution to this?
