I am pleased that hybrid vehicles have been invented to save on carbon emissions Yeah, those hybrid vehicles are know for using two or more types of power. What are the two types of power? Well, it can be combustion engine and electric generator which gives power to an electric motor Are they affordable for the average person? I am not sure about the cost but I can say there are tax exemptions included, also additional perks and tax credits That is a good point.  What else do you know about them?
In 1995 Thomas Muller designed and built a ''Fahrrad mit elektromagnetischem Antrieb'' for his 1995 diploma thesis.
