Solar Cars in Our Future Eilat – Ludwigshafen – Ljubljana, December 2014 Team: SOLAR CARS RENAISSANCE Authors: Olga Tsessarski, Miguel Thomos, Jaka Petrovčič

Introduction Photovoltaics developing alternative Work towards energy autarchy of the cities Clean solar energy fuel for vehicles

How solar cells work? Two different types of semi-conductor layers (sillicon) Two layers together => P-N junction Difference in electrons causes current

Brief history The first solar car was invented 60 years ago In 1981 Tholstrup built a solar powered race car in which he crossed Australia Breakthroughs through the years First solar car

Brief history New cars been developed… World Solar Challenge invented by Tholstrup, an australian solar car inventor Modern racing solar car

Advantages of solar cars NO AIR OR NOSIE POLLUTION The purchaser does not have to purchase USUAL fuel Cheaper and less regular maintenance service than conventional cars (Blue, 2014)

Current problems People are not driving solar cars now because: None commonly available in market Too small Design is not appealing to the consumer Not reliable, fuel problems

Dream cars? Nowadays solar cars Would you buy one like this?

The car solution 4 m 2 of semi-flexible solar panels 8h recharging from the sun Grid battery charging: 4 h completely, 20 min for 80% full battery 1000 kg full 150 km range $ 4 seater 120 km/h top speed 80 kW motor (Bosch)

Comparison Drag coefficient kW Drag coefficient: 0.28 Electric motor Petrol motor 80 kW

The city solution Picture 6: State’s investment into solar panels near parking lots Recharging cars from the grid(plug in), for a price

Conclusion These solutions would slowly convince the population to change their way of transport. Change the way of thinking Less consumptionate society
