See what it takes to sound the foghorn at Sumburgh Lighthouse on Shetland Island in Scotland. In the video above, lighthouse engineer Brian Johnson starts up the three Diesel Kelvin engines, powering the compressors that power the foghorn. From SumburghHead.com:
The Sumburgh Head Foghorn is a striking landmark. Recently restored and re-painted, the bright red trumpet points out to sea as it has since it was built in 1905 and put into operation in 1906.
The Foghorn was last sounded in 1987, but will now sound again on special occasions.
It takes around 25 psi to power the foghorn – the pressure being generated by the engines in the Engine Room. During the refurbishment project, the foghorn was returned to working order and is, we think, the last working foghorn in Scotland!
Drive up to Sumburgh Head, just beyond the sheep, on the first day of the visitors season to hear the foghorn in this video by Peter Brindley:
