Britain's World Solar Challenge Entry - Bethany
Weighing just 160kg and covered in 6 square meters of the world's most efficient silicon solar cells,
CUER's engineering team has systematically reduced energy usage for each component of the
car to the point it uses up to 50 times less power than a normal petrol vehicle
car; and with potentially infinite range.
Technologies used include a 98% efficient electric hub motor, control systems providing battery management and regenerative braking, lightweight mechanical design, and carbon fibre composite bodywork.
Bethany is by no means a luxury vehicle and the drivers will undergo months of training to cope with Australia's weather conditions and the awkward seating position. Perhaps one of the greatest challenges for the drivers will be boredom as they make their way across the sun-baked outback as during the race they will only be required to steer the car and stay alert as the vehicle's advanced cruise control system will automatically adjust its speed according to conditions.
