Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do.

There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

The Missing Link

Government wants to put on the roads , some 6 million Electric Cars by 2022

Only problems are :

·         Li-ion Batteries cost almost 50 % - 70 % of the car price

Sunil Jain ( CEO – Hero Future Energies Pvt Ltd ) says :

“ After 2020, the battery price is going to become one-third of what it is today . Technology is changing very fast . We are looking at Solar Charging Stations

·         These batteries are huge and take 30 – 60 minutes to re-charge ( who would want to line up in a 1 KM long queue , at Kemp’s Corner charging Station ? )

If battery costs keep dropping by about 22 % each year ,after 2 / 3 years , selling price of EV will come down to below the selling prices of Petrol / Diesel cars !

That leaves the problem of ULTRA QUICK re-chargeable batteries

Fortunately , many battery manufacturers’ R&D labs and University labs are working on this problem

Following news ( on the web ) is just one example :



A technology developed by Purdue researchers could provide an “instantly rechargeable” method that is safe, affordable and environmentally friendly for recharging electric and hybrid vehicle batteries through a quick and easy process similar to refuelling a car at a gas station.

The innovation could expedite the adoption of electric and hybrid vehicles by eliminating the time needed to stop and re-charge a conventional electric car’s battery and dramatically reducing the need for new infrastructure to support re-charging stations.

John Cushman, Purdue University distinguished professor of earth, atmospheric and planetary science and a professor of mathematics, presented the research findings “Redox reactions in immiscible-fluids in porous media – membraneless battery applications” at the recent International Society for Porous Media 9th International Conference in Rotterdam, Netherlands.

Cushman co-founded Ifbattery LLC (IF-battery) to further develop and commercialize the technology. ( drbigjohn@gmail.com  )

“Electric and hybrid vehicle sales are growing worldwide and the popularity of companies like Tesla is incredible, but there continues to be strong challenges for industry and consumers of electric or hybrid cars,” said Cushman, who led the research team that developed the technology.

“The biggest challenge for industry is to extend the life of a battery’s charge and the infrastructure needed to actually charge the vehicle. The greatest hurdle for drivers is the time commitment to keeping their cars fully charged.”

Current electric cars need convenient locations built for charging ports.

“Designing and building enough of these recharging stations requires massive infrastructure development, which means the energy distribution and storage system is being rebuilt at tremendous cost to accommodate the need for continual local battery recharge,” said Eric Nauman, co-founder of Ifbattery and a Purdue professor of mechanical engineering, basic medical sciences and biomedical engineering.

Ifbattery is developing an energy storage system that would enable drivers to fill up their electric or hybrid vehicles with fluid electrolytes to re-energize spent battery fluids much like refueling their gas tanks.”

Without losing time , India should include this technology under :
