Thank you for your advice.
I have been looking for contact details of Mr Van Der Walle but haven't been able to find anything. I would of course get in touch with him, I've read his Thesis from his time at KTH and found it extremely insightful.
My reason for contacting Bart De Wert is mainly that his Velo is quite symbolic in the context of my rationale for the Velomobile as a commuting vehicle rather than solely foe enthusiasts. but it's not necessarily representative of my ideas of a Velomobile for the masses.
If you can provide some contact details for Frederik Van De Walle or even a place I could look then I would be very happy indeed.
Thanks,
Daniel
