Hybrids

My Fijian neighbours' daughter has been on vacation in Costa Rica for some time now. Their family is a mix of Chinese and East Indian. Their daughter was married to a black Caribbean and has a son and daughter from him. So, her children are Mongoloid-Caucasoid-Negroid-Australoid hybrids.

Hybrids use both the familiar gasoline engine and an electric motor in a clever combination governed by computer. The end result is greater fuel economy and less air pollution.
