First of all, thanks guys for the responses so far!!

I think it is useful to give some more details about our trip:

@mollydog
1. the challenge we face is to make an electric vehicle; we choose a motorcycle and we will build it ourselves.
2. 30 students, because that's the amount of people we think we need for this project to work. We need to build the bike, need to plan everything and need to look for sponsors
3. we are doing this because we want to promote electric vehicles. By travelling around the world, we want to show that electric driving is possible.
4. No, our goal is not to make profit, but to promote electric driving. The costs for the students is the work they do for the project; so we need funding also

The suggestion given about travelling like a military operation is indeed how we think we will be doing it. Important to know is that we won't be traveling with 30 motorcycles. The goal is to run at least 1 motorcycle and driver, who will be traveling the whole trip. The rest of the team will be there for support, and thus likely in cars. (We are still figuring out what kind of vehicles we want to bring and how many, we also need to sleep and this will be probably in tents next to the road...)

And yes! The HU site is indeed very helful!! The reason we started on this forum is to start a discussion about our specific trip. We know we have to take into account a lot of different things and we don't want to miss any information. So every comment will be considered and was very helpful so far!
