After months of hard work we revealed our brand new solar car Nuna11s today in the theaterhangaar in Katwijk. Starting the day we drove Nuna on the airstrip for all the attending press. After this we gave a presentation to our friends, family and partners about the challenges we face this year and how we plan to overcome them. But most importantly we explained all about the new innovations in the car. Our guest speakers: Joos Ockels (former wife of Wubbo Ockels, the first dutch astronaut) and Edward van Hek (the pilot who will fly our car to South Africa) also gave inspiring talks. Afterwards it was time for drinks of course! We received a lot of compliments and positive reactions, all in all a successful day!

Motor of the future

The most important innovation of this year is the new in house built motor. It is the first time in the history of the solar team that we developed our own motor. In doing this we managed to fabricate a motor that delivers twice the power compared to older models. On top of that the motor is also more efficient. All this is possible due to a new coil configuration called dual air gap. With this new motor we are confident that we are prepared for the mountainous areas of South Africa, something we struggled with in our previous race in Morocco.

Solar panel & Battery

We also made improvements on our solar panel and battery. The new solar panel is adjusted to work efficiently in all circumstances and environments. By using diodes in the solar panel, specific solar cells can be bypassed. When a shadow is thrown on a traditional solar panel the whole panel or zones of the panel are turned off, with the bypassing method only the part the shadow is thrown on can be turned off. The battery was also improved, by using lithium ion technology the weight of the battery pack has been reduced by 50% to 20 Kg. A new production method was used and we made sure the battery is both trustworthy and safe.

Design

With an innovative car comes a futuristic look. Normally the car features orange elements and a lion graphic, this year we wanted to do something different. We wanted the car to look like a race car and a real eye catcher. Inspired by the sunset in south africa we chose a colorful gradient following the shape of the car. A blown up version of our starting number 03 is placed at the back of the car. when looking at it from exactly the right you can see the whole 03. Just above the wheels a strip of carbon fiber is displayed, this way the ‘inside’ of the car can be seen on the outside. Most striking however is the matte finish, it is the first time ever the car does not have a gloss finish.
