Here’s a 10 year old technology that may have its day in the sun in lightweight cars - pardon the pun. In the Aurora solar car below the single front wheel motor is able to drive the car up to around 110kms per hour.
Here’s the link to the
World Solar Challenge website
Nine of the forty vehicles slated to compete in this year’s World Solar Challenge from Darwin to Adelaide are using a highly efficient electric motor designed by CSIRO. In the last event in 2005, only three teams had ‘the CSIRO advantage’. |
| CSIRO’s motor is the most efficient in solar racing at 98 per cent efficiency (converting 98 per cent of its fuel – electricity generated from sunlight – into useful power). It’s also extremely light: the whole wheel – tyre, motor and all – weighs 14.5 kilograms. Other in-wheel motors used in solar racing typically have energy efficiencies of less than 95 per cent and weigh twice as much, not including the wheel and tyre. |
