Climate Change impact is very clearly visible on lockdown for COVID-19 virus and it's effect on those living in more pollutions & loosing their immunity against germs.
Emissions from fossil fuel are major contributor of Climate Change and road vehicles emissions is its major sector.
For reducing road vehicles emissions to zero, invention for operating Electric Vehicles ( Zero Emissions) directly powered by pair of overhead supply line from Grid/ power source. The heart of invention is keeping Electic vehicle operating similar to gasoline as take over, lane changing, Turnings, etc using single arm connector for both supply line at any position without short circuit.
Now green energy renewable energy source to feed electric power to overhead supply line is needed.
Hydrogen fuel cells vehicles are mentioned as ZERO emissions with outlet water vapour& electricity but water vapour is great GHG emissions . Can Hydrogen fuel cells based power plants in modular form with 600 V DC supply of capacity according to demand along road side be made.
Those having experience for green renewable energy source may suggest option to start EVs for zero emissions to save Climate Change.
Any electric vehicle may get benefit of overhead supply means all road vehicle may be converted to ZEVs.
