Length: 5 m Width: 1.8 m Weight: 300 kg Top speed: 170 km/h To reach a speed of 100 km/h requires 1650 W, equivalent to the power used by a hair drier [2] The body was made from carbon fibre, reinforced with Aramid.
[1] Nuna 2 used three-layered triple-junction gallium-arsenide solar cells developed by the European Space Agency through its Technology Research Programme.
Nuna 2 was fitted with 3000 solar cells mounted on the top and the sides of the car.
A total of 46 lithium ion (Li-ion) battery cells were connected in series to supply 5 kWh (18 MJ) of electrical energy.
These highly efficient batteries were originally developed for space applications where reliability is essential.
