Conversion Time18 months
Conversion Cost20 000 + 20 000 for batteries, all parts except the generator have been reused in Bolt
Additional FeaturesWe are now building (with help of Actinia solar) a 3 kW solar power plant to charge this car to follow the idea of Solar mobility
Since 14.may 2008 the car has been equipped by Li-Po batteries! They are something completelly different from Trojan Lead acid we had before and I think they can ruin the petrol domination.
E Espace was dismantled in may 2009 and another car "The Bolt" has been built from its components. The car was too old and it would need complete refurnishing.
Retired April 2009 as it would be too expensive to buy a new set of LiPo batteries for our new project "The bolt".
As new LiPo batteries are very powerfull the generator was no longer needed, so it has become just an additional weight. Basically a pilot learning project..

On the road from August 2007 till April 2009 doing 13000 electric km and about 500 hybrid km miles without much troubles or breakdowns (2 breakdowns).
Basically we did it to prove that it is possible and that if 3 men in a garage can do it, a car manufacturing company could do it much better and cheaper. So there is no will....
