>>1991487>I think a big problem with this style of velomobile is that windows are too big. And on the sun it becomes an absolute hot box. This might be good in the winter (if you're lucky to get any sun), but in the summer it would be insane.>Windows should be as small as possible and forward slanting (like boats. see pic). this prevents direct sun exposure.>Also should be the same on the sides. Aerodynamics might suffer a bit, but if you make the window curved and on the side some channels for the airflow, I think it can be mitigated quite well.Regarding windows, Velos (not, conceptual, but real ones like Quatrevelo, Büik, Snöek, Milan, etc.) usually have the windows they have because they use the same visors as motorcycle helmets. Otherwise getting real glass, and not scratch-prone plastic to that shape isn't cheap. But what you saying is probably sensible.
Regarding heat, check pic related. Coloring of your velo goes a long way regarding heat management, also air intakes and maybe a small 5v ventilator will be plenty. But driving those things sweat free will probably only be possible with e-assist and on maximum assist.
