Solar cars which use the energy of sun and do not need petrol; can run without making noise and pollution. Staff and students at the University of South Australia have designed and built such a car—Trev.
Features of Trev Solar Car
Two comfortable seats, since more than 90% of urban trips have only one or two people in the car.
Enough luggage space for at least two overnight bags.
270kg mass—because using a 2.5 tonne vehicle for commuting is ridiculous.
Energy-efficient tyres, brakes and suspension.
A clean, quiet and efficient electric drive system.
Compliance with road safety and worthiness regulations.
Good performance, with a top speed of 120km/h.
At least 150km of city driving before the car must be recharged.
It uses less than 1/5 of the energy required by a conventional car, and can be recharged using electricity from clean, renewable sources such as solar and wind.
The tandem seating layout gives good aerodynamics, good balance, and good vision.
The acrylic canopy, with integrated roll hoop, gives the driver an unimpeded view of the road.The canopy and door open on the kerb side of the car.
A 30kW IEMS brushless motor gives smooth, quiet acceleration from 0–100km/h in under 10 seconds.
A composite tub chassis, with foam and plastic body panels, gives a total car mass of 350kg.
A 45kg lithium ion polymer battery gives over 150km of city driving.
Low-energy tyres on low-mass alloy wheels give low rolling resistance.
The single rear drive wheel simplifies the suspension, and allows a simple, efficient transmission.
