i learned this from my teacher in social science, that 10-15 years ago the hydroelectric car was invented by a Filipino but the Philippines didn’t have the money to support his invention so he sold it to the Japanese, but what if it was supported and we didn’t need to make use of oil anymore the economy of the people in southwest Asia would go down and the pollution would lessen but the people in s.w. Asia might start a war i don’t know what do you think?, this is just my opinion.
