Attention Conservation Notice: It's yet another new clean power gizmo.
(((Meanwhile, in The Hague, diplomats from half a million different countries obfuscate and fingerpoint as the planet stews and bubbles. "Agent Cherry Pie" and "Agent Sushi" just hit the American negotiator with a chocolate cream pie. At best, a melancholy spectacle.)))

(((Never mind the politics. Where's the power happening? A rather interesting development this week in Scotland. This wave-power device seem especially apt since a recent climate report states that the planet's waves are getting bigger and more violent.)))
"INVERNESS, Scotland, November 21, 2000 (ENS) == The
world's first commercial wave power station has been
connected to the national grid in Britain. WAVEGEN and
Queen's University Belfast jointly developed the LIMPET
(Land Installed Marine Powered Energy Transformer) wave
system with financial support from the European Union.
"The LIMPET is operating on the Island of Islay, off
the West coast of Scotland, famed for its unique whisky
distilleries. (((Yee-haw! Green-powered single-malts!)))
"This first site will generate 500 kW of renewable
energy without greenhouse gas emissions. That capacity is
sufficient for 400 local homes. (((Or one distillery,
"'This is a big day for us,' says managing director
Allan Thomson. 'Wave power has joined the important group
of commercially viable, competitive and clean forms of
sustainable energy. This is the launch of a new global
"LIMPET offers modular construction and simple
operation, and company officials predict its applications
will fill a growing need in coastal communities around the
world that are trying to replace diesel generation. (...)
"The LIMPET uses an oscillating water column in an
inclined concrete tube that has its opening below the
water level. Wave action causes the water level in the
collector to oscillate, and this variation alternately
compresses and decompresses the trapped air in the column.
The air flows back and forth through a pair of generating
turbines which are driven in the same direction at all
times, regardless of the direction of the airflow.
"The unit is designed to operate on the shoreline, or
it can be incorporated within rubble mounds or caisson
breakwaters to provide coastal protection schemes as well
as power generation.
"Key features include low cost power, maximum local
content and 60 year life with minimal maintenance.
(((Hands up everybody who thinks the shoreline of Scotland
is still going to be there in 60 years.)))
(...) "WAVEGEN is backed by UNOTEC Holding AG of Switzerland, AGIP UK of Italy¹s ENI Group, and the European venture capital company 3i. The company was established in 1992 by Thomson and professor Alan Wells, inventor of the Wells air turbine."
