ET3 Global Alliance

Therefore ET3 will not likely serve remote islands, or an isolated cabin in the woods (unless along an advantageous route between population or resource centers). The optimal economically feasible cargo load weight (800 lb (365 kg passenger, 900 lb (410 kg) cargo) of ET3 is limited compared to a: truck, cargo aircraft, train, barge, or ship capable of carrying loads of many tons. This limitation is shared by automobiles, SUVs, and motorcycles. ET3 is not viable for transporting adult elephants, however the ton/hour capacity of ET3 can be greater than a double track heavy rail line. Our research shows that about 94% of cargo can be accommodated by standard ET3 capsules 1.3m diameter X 4.95 long, (more if disassembly is allowed). By contrast a standard 40 foot shipping container can accommodate about 98%. Finally, there is an energy and time overhead for a capsule to enter / leave the tubes through an airlock and recharge the air system and maglev cooling system. This limits the usefulness of ET3 to trips longer than about 10km (6 miles). See the attached file showing ET3 constraints.
