Electric Solar Tuktuk

Electro Solar Cart
Eco-friendly and the first of its kind, Syed Sajjad Ahmed has built a battery-operated solar-powered cart for city mobility.

In the interest of cleaner, cheaper transportation, not to mention humorous melodrama, this blog mentioned possible development of an Italian hybrid scooter. Whereas it is difficult for alternative models to compete, in terms of cost effectiveness, with vehicles powered only by small two-stroke or four-stroke, gasoline engines, nonetheless, there is a trend, especially in densely populated urban centers, to require better compliance with global emission standards.

Tuktuk
Example of the small, three wheeled vehicles common in India, Thailand and throughout South / Southeast Asia.

Beside hybrids, another alternative is fuel cell power. Both offer improved performance over battery powered, all-electric, vehicles, although as previously noted, development is underway in that segment as well. Which is reason to take note of a cart designed by Syed Sajjad Ahmed.

Writing for the Hindu (May 31, 2006), K. Satyamurty reports that, with support from several organisations, including the Centre for Environment Education and UNDP’s Small Grants Programme, Ahmed built an ‘Electro Solar Cart’ powered by batteries that has solar cell back-up.

As the Hindu article implies, if the price of the electric drive train could be brought down, such a vehicle could become highly marketable in countries that lack adequate oil supplies. Market estimates show a potential demand upon European production of 24 million two-wheeled scooters annually. And, the potential market in Asia for a clean alternative to what is now used to power low-end mass transport vehicles dwarfs that number.

Ahmed’s battery-powered cart “can run up to 50 km at a speed of 30 kmph to 40 kmph, which is ideal for city traffic conditions… After being recharged, on a sunny day the solar cells get charged more or less on a regular basis and chances of running out of power are rare in a city,” he explains.

SunVee
The Sunmobile, a prototype, four-wheeled “lead sled” with bicycle tires and in compliance with safety standards for low-speed and personal transportation vehicles.

While such detail is missing from the Bangalore story, one might assume that this electric three wheeled cart uses a standard 48V system. Personally, this blog likes the greater stability of four wheels and the solar panels that shade the driver as well as the passengers.

Electro Solar Car
Ahmed’s electric vehicles with solar supplemental power are examples of the type of innovative tinkering one sees with electric vehicles.

Syed Sajjad Ahmed also has developed solar powered, two-wheelers, which can be comfortably used by the physically disabled and can run for 20 km after every recharge. While solar backup adds expense, such development is several orders of magnitude cheaper than fuel cell wheelchairs.

    While always parking in the sun captures the imagination, especially of those who at the end of the day, have come back to an oven on wheels, I prefer solar powered, stationary, charging stations. Carrying the photovoltatics everywhere you go would seem to increase the risk of damage to quite valuable equipment. There is an advantage to such supplemental photo voltaic power, a.k.a. “trickle charge”. “Gridable” vehicles have many components in common with solar power. Nevertheless, until solar panels become relatively inexpensive, the potential loss seems to outweigh potential gains.

    On May 30, 2006, timmi of Small Efficient Vehicles expresses doubt as to whether a three-wheeler is the answer… at least, not in Canada since, while three-wheelers are legal in Quebec, Alberta, and British Columbia, they are illegal in seven other provinces.

    Besides, we want to design something that can be replicated, with equal quality and characteristics, which is not something you will get from a junkyard project.

    He also notes, “we already have a nice little three-wheeler in production called the TRex” that out-accelerate and out-corner almost anything on the road.

    And, a history lesson from HybridCars.com: in 1888 Magnus Volk in Brighton, England made a three-wheeled electric car.

    Also, EVs in Kathmandu tells us about the recent history of three wheel electric vehicle in Nepal:

    From 1993 to 1996 at the request of the Municipality of Kathmandu, Nepal, GRI initiated a very successful electric vehicle program to help alleviate the severe air pollution in that city. This program, supported by US-AEP/NASDA, USAID/Nepal, and US-AEP designed and introduced the SAFA Tempo, a battery operated three wheeler which operates as a mini-bus carrying 10 passengers on fixed routes in the city. GRI built a demonstration fleet of eight SAFA Tempos and operated them as a transportation company for six months. The vehicles carried over 200,000 passengers and travelled over 175,000 km. during the demonstration period.

    In an equally significant component of the program, GRI worked with the government of Nepal to reduce duties on electric vehicles and components and to establish other incentives for electric transportation, with the private sector to develop business plans, and with the public to raise awareness of the benefits of electric vehicles.

    For a report on the program in Nepal, Promoting Electric Vehicles in the Developing World, presented at the International Electric Vehicle Conference, November 1998, San Jose, Costa Rica, click here.

    Since December 1997 significant strides have been made regarding electric vehicles in Nepal:

    • To date five companies have manufactured over 600 SAFA Tempos and have provided battery exchange services.
    •SAFA Tempos are carrying millions of passengers a year in Kathmandu and other cities in Nepal and widely distributed battery charging stations have been established.
    • The Nepalese government has banned all diesel three-wheelers from Kathmandu.
    • Public pride in the electric vehicles and preference for them have truly developed into local ownership of the electric vehicle program. Over the past eight years, public demand for electric vehicles has thwarted numerous attempts to bring diesel three-wheelers into the Kathmandu Valley.
    •Local industry is now producing battery chargers, forward/reverse switches, and other components for the electric vehicle industry and is providing maintenance for the vehicles.
    •Almost all of the development of the electric vehicle industry has taken place in the private sector without foreign aid.

    In 1997 at the conclusion of its electric vehicle program in Kathmandu, Global Resources Institute received support form SNV, the Dutch NGO, for further work on electric transportation in Nepal. Since then GRI’s activities in electric transportation have continued in Nepal and have expanded to other countries in Asia and Central America and to the Pacific Northwest.

    A report by Anil Baral, “The Electric Vehicle Industry in Nepal” can be found in Home Power Magazine, #79, October/November 2000, pages 74 – 78.

    Robert McLeod states that a car-mounted small solar panel is incapable of contributing even a small amount of the energy actually needed to move a car.

    Which was my gut feeling in response to the Electro Solar Car, but it always is nice to have someone who likes numbers to run them.

    Note: McLeod’s comment post was about an Energy Pulse article promoting solar panels integrated with hybrid cars and his calculations were based upon the amount of sunshine in Los Angeles.

    It may be a good thing to focus attention on two potentially valuable technologies: electric vehicles and photovoltaics. Nonetheless, to create unrealistic expectations inhibits development.

    jc,

    Yow, I learned more about current hybrid possibilities here than I have in ten other places. Thanks for the great info…I’m tracking the links now to great effect.

    My first visit here, but I LOVE the amount of specifics and product-related info. Thanks!

    Brad
