In her Backreaction blog Sabine Hossenfelder has a report on a New type of gravitational wave detector proposed . The proposal suggests that instead of long lasers we use atomic clocks. Since the gravitational waves would change the time of the clocks as it passed then we could detect the difference in the times to catch gravity waves. It does require long spacing, so it has been suggested that we place a bunch of clocks in orbit around the Sun. Not real cheap, but it does sound rather practical.
