However, until Freedom Motors has the Rotapower® engine in at least limited production, MI is not interested in promoting the Skycar® further. It only brings additional interest in the Skycar® from the general public, and they also question why MI has not yet produced it.
Within the next few years battery powered air-taxis will be available for trips up to 25 miles between vertiports for one or possibly two passengers. How far beyond this distance and payload can safely be flown will depend on battery life. When I mentioned these limitations during the recent SAE Aerotech Conference, a member of the audience asked, “why not use a bigger battery”. The answer is that as all-up weight (AUW) increases, the energy required from the propulsion system increases much faster. Energy from batteries is so low that adding a
