  What do they think open air means?
context: A huge solar farm – the equivalent of 35 football pitches – is being planned at Bern Airport aimed at producing electricity for up to 15,000 homes from 2026.
  Flughafen Bern AG and the energy company BKW have joined forces to launch the “BelpmoosSolar” project. They want to install solar panels on one-third of the land at Bern Airport, approximately 25 hectares, to generate up to 35 gigawatt hours (GWh) of electricity per year, a joint press release said on Friday. Around 30% of the electricity will be generated in winter.
  “The "BelpmoosSolar” project is proof that the central Plateau region [of Switzerland] has suitable sites for large-scale, open-air solar plants that can generate large amounts of electricity in a region that is already populated and close to residential and business centres,” the statement said.
  The project is expected to cost around CHF30 million ($32.24 million). Official planning approval is still needed for the proposal.
