Strängnäs, Sweden
Need: to transport ourselves over 500 meters of lake to get to our place.
In the summer, a small aluminium boat with a powerful little electric motor is perfect. In the winter, walking is great because the lake freezes.
In the autumn, and the spring, the ice is weak, so we need a mode of transport that is safe and reliable, thus the airboat.
I love electric vehicles, electric bikes, built a speedy little electric outboard last year, so the choice was easy. Go all electric!
