How much is a renewable car toy better?? Can we direct only renewable sources to renewable cars?

[6/14, 06:07] Harish Exinc Teaching & stnr 716: The biggest way for renewable is for your kid to carry any brand toy car in hand to museum to see all sources in perspective.. an architect had asked it and I failed in 2001 without that visit.. Harsha Sridhar Should we write in Indian languages too as my mom thinks I don't know..
