Electric roads would pave the way for smaller car batteries, shows modeling study
If an electric car charges while driving, the size of the battery can be reduced by up to 70 percent, and the load on the power grid can be spread out over the day. Charging on the move suits most people, but not everyone. ...

Hydrogen cars won't overtake electric vehicles because they're hampered by the laws of science
Hydrogen has long been touted as the future for passenger cars. The hydrogen fuel cell electric vehicle (FCEV), which simply runs on pressurised hydrogen from a fuelling station, produces zero carbon emissions from its exhaust. ...
