Eternium has spent the last 10 years holistically perfecting the architecture for what will become the first ultra long range zero emission aerial vehicle by refining the power and propulsion, fuel storage and planform elements of the aircraft to bridge the known energy density gap between kerosene and hydrogen in all permutations. This is accomplished by clever engineering to increase the available energy onboard, drastically increasing thrust specific energy conversion efficiency (percent utilization of stored energy in conversion to thrust), and the efficiency at which we convert that thrust to lift while reducing drag to decrease energy and cost per mile per lb travelled.
