Just a little thought experiment for you guys.
What if you are at the top of a mountain with your Tesla and almost no battery. You can fill the trunk with rocks and also a trailer (if you have one) and then go downhill and charge the battery as much as you can with regenerative braking. You will charge a lot more than if you had no rocks or extra wieght in the car because of the extra potential energy from the rocks. When you are at the bottom of the mountain could you leave the rocks, go back uphill only with your car and empty trailer and repeat the process? It seems like a great way to get "free" energy since you are only limited by the amount of rocks you have available.
Sorry if my english is bad, it´s not my first language.
