Humans can already build a space elevator — study

Professor George Drew from York University discusses the feasibility of building a space elevator, as detailed in a study published in ACTA Astronautica. The study suggests that current materials and technologies are sufficient for constructing a profitable space elevator. The proposed design involves two parallel tethers, which would enhance stability and efficiency. The elevator would operate by balancing opposing forces, reducing the impact of Earth's rotation. This innovative approach could significantly cut costs and fuel usage for space transportation.
