Their primary income is from the support organisation. It costs 100 Danish kroner a month (roughly $20) and there are around 700 members. So they live on roughly $14.000 a month, or $170.000 a year.
Needless to say there is a lot of ingenuity in costcutting, a lot of parts from home-depot....
Even though the small budget is very impressive, we wouldn't mind to have more members in the support group. Ahem... :-)
