Blimey Ken - I think I will defer those questions to the master of neoprene as they are two I do not know I am afraid. My focus is now on Drones at the moment. Lots of fun and investment starting to occur around these mosquitoes.
Wait for the future stuff around drones and AI in crops and farming. Some real early money going into this right now. Drones being used to test soil and monitor growth then plan harvest etc etc.
