I heard that China was going to release cars that would work without oil products and electricity. I dont remember what was said in that article, but it said that China was going to produce these eco-cars in 2020.
Don't believe on every article you found on internet.90% of them will be fake just to make revenue from ad clicks.
Its not possible to run a motor without anything,even its possible with water but its highly expensive than the oil products.
Don't believe statistics, 'cause 87.4% of them are made up on the spur of the moment.
