His motivations for 2024

Most Czechs are climate change deniers and also sceptical about renewable energies, so I am seeking fun and cool way to communicate the situation and possibilities. I want to generate some content for decentralized social network Mastodon (part of Fediverse). I want to showcase our solar bike design (which is closer to solar motorcycle) and also promote the cargo bike frame design we used as chassis (with Jirka Štrupl). I like to travel and spend time alone in nature. Never before visited Africa. And I would also like to race a little.
