Hypersecretion - Too much of any hormone secreted into the body is usually caused by a secretory pituitary gland tumor. Secretory tumors produce too much prolactin (the hormone that triggers milk production in new mothers), which leads to infertility, discharge from breasts and menstrual abnormality.
Roadster uses about 230Wh/mile at 55mph, we know that Model S 85kWh battery should last 300 miles at 55mph. That gives us 283Wh/mile. Difference is 53Wh. Roadster uses about 330Wh/mile at 75mph, so Model S should use 383Wh/mile at 75mph. 85kWh/383Wh/mile = 222 miles. Estimation, but should not be far from truth.

And he wanted it to be the size of a watermelon.
