I don't know if there have been so many major developments in power electronics on the grid side in the past 30 years ...
By cons since there are better batteries and super condos ....
In terms of energy management and investment cost, I think an on-board battery to make a micro-hybrid storing the energy of X braking (with X <5) to help the next start instead of pumping on the network is much better than network injection ... AMHA!

There yes, with the Arduino and co, we do miracles at a reduced price!
And it is never too late to act: there is (at least) 100 years of oil (yes!)!

No luck but it's been a nice hike !!
It seems to me that it broke down this summer a few weeks after my visit ... (I swear spit jury is not me, I have not sabotaged the non recovery of energy !!! )
