I feel there is a very good chance that Elon Musk will save the planet when he brings 'free energy' to the people. Potential headlines: completing the dreams of Nikola Tesla from the early 1900's, in 2025 Elon Musk successfully completes the experiments and reveals 'free energy'. This was Nikola Tesla's long term goal, to give power away to the masses. There is potential energy surrounding us, much has been harvested: steam, wind, solar, power conversion via waterfall & flowing river, thermal heat of volcano's and hot springs, naturally occurring phenomenon can be used to turn a wheel converting mechanical (rotational) energy into electricity. Made up of coils of wire that are either rotated through magnetic fields or are stationary around a shaft with rotating magnets. The turning motion is required, but available from many sources. I believe this technology has been available but has historically bought and shelved to prevent production. Allowing elites to continue to keep normal people oppressed. They perpetuate this system by hiding many technologies that could benefit mankind. Elon Musk wanting to help the species survive has focused on developing multiple technologies, when considered as a whole, seem to demonstrate his work towards achieving these admirable goals. Electric cars development has lead to great leaps in batteries for energy storage. Solar City, him and his brother started this company to harvest energy from the sun. Space-X has surpassed all abilities of NASA on a much smaller budget. Ultimately he hopes to build a colony of humans on Mars, thus increasing the odds of the survival of the species. The 'Boring' Company, is another of his creations that is creating large tunnels below ground potentially for high speed rail, private highways, or other similar transportation that will be automated thus relieving congestion.
