Story summary

David Kipping proposes TARS, a solar-powered centrifuge for interstellar travel without fusion reactors or chemical rockets.
TARS employs reflective paddles to capture solar energy, potentially launching probes at speeds above escape velocity.
Its quasite design allows efficient solar energy use while orbiting the sun slowly.
Kipping suggests carbon nanotubes or graphene to enhance tensile strength and release velocity.
Although theoretical, Kipping has attracted interest from private spaceflight companies for a prototype.
