A new research report says a hyperloop, the high-speed travel concept, is at least 20 years away from commercialization.

The big picture: Climate change has fueled interest in finding low-carbon alternatives to conventional rail and air travel. An electric hyperloop is one solution, because it operates in a vacuum system that reduces aerodynamic drag, enabling higher speeds and greater energy efficiency.

  • Passengers would ride in levitating pods inside a narrow tube at speeds well above 500 mph.
  • Virgin Hyperloop One explains the technology in this video.

Yes, but: A new report from Lux Research says while the concept is technically feasible, it will require significant development to become cost-effective.

  • "Despite the considerable amount of hype and attention hyperloop has received and the potentially important role it could play in decarbonizing long-range transit, the concept remains more or less unproven, and serious questions remain about its economic feasibility," says Lux Research Senior Analyst Christopher Robinson.

The bottom line, via Lux Research: the first passenger-carrying high-speed hyperloop systems won't begin operation before 2040 at the earliest.

A just-published Brookings Institution analysis of U.S. cities' pledges to cut carbon emissions reveals very mixed results.

Why it matters: The potential — and limits — of city and state initiatives have gotten more attention amid President Trump's scuttling of Obama-era national policies.

First-time applications for unemployment fell last week, according to Department of Labor data released on Thursday.

Between the lines: The overall number of Americans relying on unemployment also fell to a still-staggering 23 million. But there are continued signs of labor market strain, with more people shifting to an unemployment program designed for the long-term jobless.
