ViWA Sarvajanik Tantra Mahotsav



We will buy two old auto rickshaw and completely disassemble one to show all parts and Mark those which would be replaced with new parts for Make-in-ViWA Rickshaw. Other one would be actually fitted with kit and made available for trial.

In January 2019 there is Pune auto-expo. They have agreed to make this as star attraction for show and we are crowdsourcing the costs if two old rickshaw and inviting offers from kit builders to take challenge

Complete process of re-fitment of kit would be shown as video in exhibition and paid training workshops would be conducted later by ViWA. Preferably the parts in kit should be such that drawings would be released for anyone to make most of them in any workshop. Battery and motor drive could be provided as two separate items with all drawings for mechanical fitment released in open source

We will form temporary “ViWA Sarvajanik Tantra Mahotsav Samitee” to manage this annual event just like Sarvajanik Ganeshotsav.

“ViWA Sarvajanik Tantra Mahotsav” announces interesting program for BUILD AND WIN under which one can join in with contribution of 10000 Rs. for one entry and actually build one electric rickshaw from parts and stand a chance to win it by draw. Come over and join and spread the word!

We can formulate such draft of ideal labor laws section by section so that we can send it to minister Mr. Suresh Prabhu, so he can follow up with his colleagues in the ministry.

We already have law which allows us to employ anyone for a fixed duration without any obligation to continue services after the period. We have to provide minimum wages and CPF & ESIS cover. Up to three years.

A lot is being discussed about electric vehicle! Lot is being discussed about environment friendliness of electric vehicle! Lot is being discussed on economical running cost of electric vehicle from consumer point of view!

Can really an electric vehicle be environment friendly? unless it is made compulsory to use solar charging and in no case from utility power by electricity boards ?

Can experts give their opinion on following calculations and let me know "where my calculations are wrong!"

Here, I have presented CO2 emission comparison. But same is true for CO, NO2, and SO2 pollution as well. In addition, Mercury pollution is there only in power generation plants and not in petrol and diesel fuel powered cars!

In India, major electricity is from thermal power plant. So is it a myth and propaganda by electric vehicle lobby and Lithium battery lobby, or truly it is environment friendly? Is compulsory solar charging the only option to counter the pollution? Should the solar energy and subsidies on solar energy be a priority for government than subsidies for electric vehicles?

Can we have a debate on this and educate people if the calculations presented are correct!

I would be happy if I am wrong! I would be glad if we are on correct path to save environment! But is it really worth it? Experts! Please enlighten me!

Case study: Mahindra Reva for calculations

Charging option: Electrical power supply from electricity boards.

Here is the calculation

  • 16kWhr is the battery specification of Reva
  • Per charge it drives maximum 120 km max
  • So we get 16/120 =0.133kwhr/km

Now considering charger efficiency of 95 %
Power required to charge this battery would be 16/0.95=16.85 kwhr energy needed to charge the battery.

So we effectively get 0.140kwhr/ km.

Assume T& D losses are 15%
(actually they are @20%, but taking a better figure here)

Hence power generation required for 16.84 unit would be 19.36 units.

Now we need to generate 19.36 units for 120 km.

Customers' running cost per km:

Battery replacement cost is @200000 after 50000 km (Assumption based on the warranty and lease schemes for battery)

Which comes around 4 rs per km

Electricity cost @ 1.70 per km

Total becomes 5.70 Rs/km

For comparing it with alto @15km/ltr and much better power.. cost of running is Rs.6 per km even when petrol is 90 Rs per liter.

Pollution Factor:

According to the data base of power ministry on CO2 emission per unit generation in India (Ref:, 1 ton CO2 emission per 1 MWH electricity generation.

For 19.36 unit generation the emission would be 20 kg.

So the emission of CO2 for running the car for 120 km shall be 20kg CO2. Which makes 166 gm/ km.

Where does it stand compared to petrol vehicle?
As per European norm, a light motor vehicle CO2 emission regulation is 135 gm per km. This is going to be 95 gm/ Km in 2020.

What is needed is India should also start implementing CO2 emission norms same as EU.

Electric vehicle at what cost?

Costly vehicle, burden of subsidies on the national economy, Lithium ion battery issues such as waste, recycling , safety etc., Lot of inconvenience of charging stations, lot less power, lot less comfort and ( if my calculations are correct )more pollution!

Better not to discuss on Lithium battery waste and recycling process pollution and environment damage! Is it worth it?

Only option is mandatory and compulsory solar charging for electrical vehical and no possibility to charge it from utility mains power! Now question is viability of compulsory solar charging!

So the question is; Why not solar energy and subsidies on solar energy should be a priority for government than subsidies for electric vehicles?

To make it viable!

Environment can be protected only if we charge the battery by solar power! Else every effort is futile!


Dhananjay Deshpande:

Ok,I have already submitted to PMO on his online website. I will send copy of it to you

Member 1:

This is a good start. You're partially right.

Solar charging could be a way out. But it's not as pollution-free as one would imagine. We need to make a huge number of solar (PV) panels - which are made from silicon (among other things) - and the processing needs ~1400 C in the furnaces - which can only come from fossil fuels. Thus, compulsory solar (PV) charging will not necessarily solve the issue.

Another, more fundamental point is - solar energy is a high-entropy energy. When you want to store it and convert it into a low-entropy (more useful) form - like a battery, you have to spend energy elsewhere. (Net entropy can only increase or stay the same).

For those interested, I recommend this short 1-page essay by Vaclavsmil

"What I see when I see a wind turbine"

Member 3:

Yes. True, but what about pollution footprint of electric vehicle!

166 gm/ km CO2 emission for just 40 BHP vehicle. As against 135 gm/ km CO2 emission for standard petrol European vehicle!

What are we gaining? Not even 40BHP, 25 BHP.

Ashok Saraf:

Thanks, it would be great idea to have it sent to Mr Suresh Prabhu ji probably through Mr. Manohar Parrikar as our hostel mate and IITB alumni.

To execute this initiative; some official identity is required. This will help to perform official communications with supporting institutes and companies. "Pune Electronics Eco System" is available as official platform for this ViWa initiative. This ecosystem is created and maintained by Arkinc Design and Communication.  Arkinc Design is also available to act as a platform for this ViWa initiative.
