How can a vehicle be both faster and more energy-efficient than conventional methods of transportation?

Conventional methods of transportation all have the problem of air resistance. What most people don’t realise, is that air resistance is a large force, especially on high speeds. You can try this for yourself: next time that you are in a car on a highway put your hand outside the window for a short while. The force on your hand will be pretty severe. Now imagine your hand is the size of the front of a train (which is maybe 1000 times bigger) and imagine you have to keep your hand still for the entire journey. That costs a huge amount of energy. The Hyperloop travels through a (soft) vacuum. By doing this we remove the air resistance. Instead of using energy to push air particles out of our way we can use it to go faster. And actually, the energy needed to go faster is way less than the energy needed to push air particles away for the entire journey. Thus by doing this, the concept is capable of achieving higher speeds with less energy.
