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.

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.

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.

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.
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:
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!
