The crown jewel of industry, another one gone, the crown is almost bald :) Musk says he wants to lower space transportation costs to the level of air freight, as low as $10/kg, so one ton would be $10,000, a 100,000-ton space carrier would be $1 billion. Solar panels covering Texas, electric cars ruling the world, space computing power, lunar bases, Mars development, Musk has already written the PPT, just waiting for China to make it happen. Feeling happy today :)
