Will Indian students' solar car make it to contest?

By Azera Rahman Sep 28, 2007, 15:29 GMT

New Delhi, Sep 28 (IANS) A bright young student team is all set to take its creation, a solar car, to the World Solar Challenge in Australia Oct 18 - if lack of funds doesn't cut its journey short.

Standing next to the three-wheeled car, roughly the size of a Honda City, 10 students of the Delhi College of Engineering (DCE) couldn't help beaming with pride.

'It took us a year to complete this car. We started working on the car in November last year. Driven on three wheels, as solar cars generally are, the car has six panels on its body.

'It has no gear or clutch and is driven by sunlight instead. There are speed controllers to change the speed,' 20-year-old Megha Aggarwal, one of the team members, told IANS.

School and college students are known to have made models of vehicles powered by the sun. But this is perhaps the first time that a full-size solar car has been put together. The team's members are mostly third year students of DCE, with just two of them from the second year.

'It was a challenge for us but we did it. From designing the car's body on the computer to putting the whole thing together... We all come from different streams - some are from mechanical, some from production while others are from electronics.

'So it helps putting all our heads together to create something,' said Harpriya Goraya, the only other girl member of the team.

At Australia's World Solar Challenge, which is a solar powered car race, the participating teams are required to drive a distance of 3,000 km over a period of eight days through central Australia from Darwin to Adelaide.

But while DCE's car is ready to see the light of day at the competition, lack of funds is posing a major threat.

'We need funds to transport the car to Australia. The cargo charges and our travel need to be funded. Although the ministry of new and renewable energy (MNRE) has supported us with Rs. 1.38 million and our college has given us Rs. 116,000, we are still short of nearly Rs.1.5-1.6 million,' said Megha.

Explaining the break-up, Harpriya said the cargo would cost nearly Rs.600,000 and the travel of the team, to and fro, would come to Rs.1 million. Besides this, the competition also requires two escort vehicles to be driven in front and behind the solar car throughout the race.

'As of now, it's just JK Tyres which sponsored our five tyre kit, besides MNRE and our college. Since the car has to reach Australia by Oct 10 and the competition is on Oct 18, we request private companies to help us with funds at the earliest,' said Harpriya.

With their competitors from America and other countries using thin panels on their cars for maximum output and not having to worry about funds, the students here feel that lack of resources are a problem in India.

'All this while we were so busy with the project that we didn't get enough time to look for funds. We had approached Maruti but it didn't work out. Resources are always a problem here.

'But we still hope that something will work out,' added Megha.

Buidling a solar car is a complex and potentially inordinately expensive undertaking when the goal is to construct a cross-continental type solar challenge car. I don't understand why the DCE team chose to build that type car knowing their resource limitations, excepting those surreal-appearing cars are quite an attention-getter. There are other categories in the Panasonic World Solar Challenge that might have allowed the team to build a more cost-effective and roadworthy vehicle - say modifying a REVA to improve efficiency and use stowable arrays to provide some of the recharge energy.

The resource question is intriguing to me. Though I live in the US, I believe there is the expertise in India to have aided the team with better resources than they may have located. Time may have been the greatest constraint, as many teams have worked hard but not been able to complete a car of this type in 2 years. As for funding, many teams outside India have fundraising and resouce issues which have been quite constraining, including some teams at major schools in America. Other teams have had more money flung at them by their schools than the bemused undergraduates knew how to spend effectively, but that's not the norm. Fundraising is a huge undertaking in itself, especially for first-time teams, and it seems the DCE students just didn't have time to work on both that and building their first solar car.
Building a solar array from scratch from those 'thin solar cells' is a tedious and somewhat complicated undertaking in itself. Not going that route likely had little to do with the team being in India. I'd say the team made the right decision in going with the pre-made panels as they were able to finish the car in time for this year's event, which is major.

I'm looking forward to see the team compete, but if the funds aren't there, I'll understand.

Much as I follow the solar challenge races, I think the event formats and vehicle types being built belong in museums, not being driven on highways and race tracks as examples of futuristic technology. The design form of these cars is quite stagnant. Covering a car with solar cells is a rather lackluster approach to recharging its batteries from the sun. Despite the use of exotic materials and expenditure of obscene amounts of money by so many of the teams, the cars are fragile and impractical beyond belief. They needn't be, but the regulations and a widewspread lack of committment to demand change ensure the cars remain what they've become - caricatures of the Junior Solar Sprint competition cars they inspired!
