Gates outlined his thoughts on electric vehicles in an August 24 blog post, writing that “better and cheaper batteries … will hopefully make EVs a realistic option for every car owner.”
But he cast doubt on whether current or even future battery tech could ramp up to power larger vehicles.
Gates, the co-founder of Microsoft, wrote: “Even with big breakthroughs in battery technology, electric vehicles will probably never be a practical solution for things like 18-wheelers, cargo ships, and passenger jets. Electricity works when you need to cover short distances, but we need a different solution for heavy, long-haul vehicles.”
Tesla is working on the Semi truck for 2021.
Gates continued that alternative fuels such as biofuels or electrofuels could be better, greener way to power bigger vehicles like trucks. Batteries, he said, are too big and heavy for longer distances.
Gates also praised several vehicle makers for producing all-electric pickup trucks, such as GM, Ford, Rivian, and Bollinger, but failed to mention Tesla, the maker of the Cybertruck pickup.
Musk’s firm also happens to be working on an electric truck. The Tesla Semi was unveiled in 2017 and was slated to be shipped to customers in 2019. But the vehicle is two years behind schedule, with Tesla now expecting to get the vehicle to owners in 2021.
