Musk is good at predicting future technology. He doesn't like Fusion Power.

"Fusion would be expensive energy, given difficulty of obtaining and transporting source fuel, plus maintaining the reactor," Musk argued in a Thursday tweet. "Far better to use the Sun — thermonuclear reactor with no need to refuel or service."

Those criticisms aren't entirely misplaced, either. Try as they might, scientists have yet to crack the code of fusion, with current reactors still requiring far more energy to get started than they're able to produce, despite many decades of research.

To Musk, we already have the answer to a much greener future.

"The primary solution to a sustainable energy future is solar/wind with batteries for when sun doesn’t shine or wind doesn’t blow, interconnected with conventional high voltage lines," he added in a follow-up. "No unknown technology is needed!"
