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.
And add on top of that lowering of productivity on all chinese factories. even if they someday wanted to make such eco cars - they couldn't achieve in 2020 at this state of economy they have now
