@sean_ae I had a similar idea given how crowded gyms are these days and how many people suffer from lack of movement - installing a cycling assembly under each desk in offices and houses with a dynamo connected to battery, which powers the PC and the monitor, so if you need more power (3D modeling, finite element analysis, or just watching 4K video) you’d need to cycle hard for a bit. Ar the end of the day you’d have enough zone 2-4 training a burned calories for the drinks later
