US-based renewable-energy specialist Ocean Power Technologies (OPT) said yesterday it had started trials of a new wave-power device in its PowerBuoy range.
The machine is much smaller than OPT’s standard PowerBuoys, one version of which is being tested about 38 miles offshore of Invergordon.
Sea trials of the smaller and autonomous Leap PowerBuoy – designed and made under a US navy coastal security and maritime surveillance programme – are taking place off New Jersey in America.
