Hyperloop 与环境：衡量什么
称一个系统可持续是不够的。严格的比较需要考虑整个生命周期：建设、运营能源、维护、材料、土地使用和报废，始终比较相同的运输能力。
能源和电力组合
Consumption depends on mass, frequency, acceleration, residual pressure, gradient and vehicle occupancy. The environmental result also changes with the electricity mix and should be reported per passenger-kilometre or tonne-kilometre.
建设和土地
An elevated guideway can reduce some crossings but requires foundations, steel, concrete, stations and access roads. Assessment should include construction, biodiversity, material use and the possibility of reusing the corridor.
待发布的指标
Every study should disclose assumptions, system boundaries, reference year and sources. Without that information, an emissions figure cannot be compared.
- operating energy and peak power
- lifecycle emissions
- noise at stations and along the corridor
- materials, maintenance and end of life
