Honourable Chief Justice, Supreme Court of India,
A few assemblers disguised as manufacturers in India, have begun marketing electric bi wheelers. However, owing to range of travel & power limitations, these are not popular although these save fast depleting fossil fuel.. However while viewing pages of www.interchina-industry.com I found there are electric bikes with motor up to 3500 watt & even with 750watt motor & 72 volt input current, 65kms maximum speed, 120kms range of travel per charge, 150kg of load carrying capacity are available costing only USD 400(Rs.23500) FOB. Honourable Chief Justice of India may direct introduction of these in public interest for reasons stated below.
Any internal combustion (IC) engine two wheeler yields about 30 to 40 kms per litre of Petrol inside city + a little of oil, costing about Rs. 55. The same range of 40 kms is covered by a electric bi wheeler in one full charge of battery consuming one unit of electricity say Rs. 5. So, vis a vis an IC engine bi wheeler rider, an electric bi wheeler rider, by saving on fossil fuel saves Rs.50 per day, if both are reckoned as traveling 40 kms per day. So an IC engine bi wheeler rider spends Rs.1500 per month more than the electric bi-wheeler rider who saves Rs.1500 per month. So in a year IC engine bi wheeler rider spends Rs.18000 per annum whereas an electric bi wheeler rider saves as much in a year!
With cost of an electric bi wheeler is about Rs. 32000, in one year plus about nine months electric bi-wheeler owner recovers price of vehicle & vehicle becomes free of cost to its owner. Whereas on an average cost of an IC engine bi wheeler is approximately Rs. 54,000, an ic engine bi wheeler owner would have spent as much as to buy a new bi wheeler in about 3 years! Plus more on replacement & spares! The cost of replacement of battery however may extend recovery period for an electric bi-wheeler owner by about 6 months!
Further, IC engines pollute atmosphere whereas electric bi wheelers are clean. IC engine bi wheeler have numerous moving parts, complicated engine & transmission whereas electric bi wheelers hardly have 5% of moving parts compared to what an IC engine bi wheeler has. Environmental pollution by discharged discarded batteries is also a point to ponder but, recycling technology that has been developed which can be employed.
IC Engines wear fast whereas electric vehicles do not. Cities will be comparatively clean. Extent of pollutants such as grease oil & fuel noise will be extremely less.
Use of IC engine bi-wheelers will increase oil import bill whereas, use of electric vehicle will save that & valuable foreign Exchange. IC engines pollute atmosphere whereas Electric vehicles do not. ( except for discarded batteries which, exist in case of IC engine bi-wheelers too)
Further, by employing the following option with required development, conservation of electricity would also result. The owners of electric bi wheelers save considerable amount of their income & ensure a better standard of living for them & their families.
It is possible to un-limit the range of travel of electric bikes to render them a success. Persons hesitate chiefly owing to frequent charging of drained batteries & prospect of vehicle remaining idle.
This can be rectified by using an alternator either to be installed inside the front brake drum by dissembling brake assembly & installing a manually operated disc brake. Inside the brake drum a circular permanent magnet be installed with stator coil attached to brake drum cover & drawing whatever current that is produced , in whatever strength, be regulated as it is varying, use a step up transformer (induction coil) to obtain required voltage & current with charging circuit, fuse etc., all in series. Chinese manufacturers of Electric vehicles have these models that are called dynamically recharging models as against conventional static recharging models.
Alternator stator windings & magnetic field strength be selected by counting the mean RPM of front wheel at say 20Kms per hour speed.
Alternatively a cycle dynamo (alternator of 12v) be installed on the rear swing arm by suitably altering diameter of rotor head to be driven by a gear toothed worn rear sprocket installed by bolting it outside rear brake drum. These may housed in a chain case type enclosure in two halves fastened to prevent it from being polluted by dirt squalor in rainy season or grime. The impedance to movement at high RPMs be considered & suitable corrections be made.
Considering all these, the Honourable Chief Justice of India is requested that he consider these as Public interest appeal & direct suitably the Government of India to acquiesce these suggestions?
