- Generating electricity through ocean-wave energy. Dam-Atoll is a Lockheed invention that was conceived and designed by scientists Les Wirt and Duane Morrow at Lockheed's Acoustical Testing Laboratory in Rye Canyon, Santa Clarita, California. One Lockheed executive was later heard to say, "The damndest thing ever to come out of an acoustic lab." While Lockheed-California Company in Burbank was the original patent assignee, the patent is now in the public domain. Directed, filmed and edited by Erik Friedl.
Fascinating... thanks for the video
Lovely cinematography
The film work is exquisite.
The device is clever.
But it would suffer in real world conditions. Salt water is far more corrosive than fresh. The ocean is full of debris that clogs the best of filter systems. And see life has a bad habit of growing on everything. May be they could have worked around it all but this isn’t the automatic energy win it may appear to be a first glance.
Excellent practical points you raise but to a creative technical mind, these could represent just another design/engineering challenge not dissimilar to trying to prevent or minimize the casualty rate of our avian friends misjudging the timing of a giant wind-turbine blade.
Less simply put, to my understanding: that starburst array of fins-combined with the dome shape that causes the water to become shallower towards the centre-funnels the water's waves into a downward vortex - a fluid flywheel - which then pushes that turbine at the base of the shaft.
It uses the refractive property of waves to accomplish this; when waves move from deep water to shallow water they change direction.
Then once the water is moving downward within the central shaft the whole thing functions like any other hydroelectric turbine.
So it's an omnidirectional underwater-waterfall generator, with no moving parts beyond the turbine apparatus at the base for harvesting the waterfall's energy. Very cunning!
Patented by Lockheed 45 years ago but because they didn't ever do anything with it beyond that one scale model in this video, the concept is now in the public domain?
Technically speaking, you're of course right on the mark and thanks for the elaboration on the inner workings of the Dam-Atoll concept. The idea remains genius-and ingenious.
So simple and clever. Thank you for sharing. And as a pianist, can I ask you about the music, please? I couldn't find it through Google or Shazam...
Thank you for your comment. The music is by pianist Marco Zannone. The piece is available on Pond5.com and is entitled "Inspirational Piano Works 2".
CO2 isn’t a pollutant; literally makes the Earth greener
CO2 is a greenhouse gas. It doesn't make the earth greener.. It is essential for photosynthesis. CO2 is a byproduct of animal respiration. However, humans are producing and imbalance in the photosynthesis/respiration cycle with our continued reliance on burning of fossil fuels, coupled with our clear-cutting of forests, and mono-culture plant crops and lawns.
Yes and no. Not to forget that carbon dioxide emissions remain the primary driver of global climate change. But thank you for the comment.
CO2 Absorbs light in the atmosphere and turns it into heat.This extra heat caused by the increase of CO2 is what is causing our planet to warm, and don't even get me started on all the effects that has.
