Hail ATLANTIS..!

Aerodynamic Turbines Lighter and Afloat with Nautical Technologies and Integrated Servo-control Generation

Program Description:
Accessible U.S. offshore wind is estimated at more than 25 quads per year (a quad is one quadrillion BTUs, equivalent to 45 million tons of coal, 1 trillion cubic feet of natural gas, or 170 million barrels of crude oil). Nearly 60% of that wind energy—the equivalent of the entire U.S. annual electricity consumption—blows across waters more than 200 feet deep, an area that cannot be economically accessed today. Floating offshore wind turbine (FOWT) technology has tremendous promise to access wind resources in these areas, but the current state of the art for FOWT is too massive and expensive for practical deployment. ATLANTIS seeks to design radically new FOWTs by maximizing their rotor-area-to-total-weight ratio while maintaining or ideally increasing turbine generation efficiency; build a new generation of computer tools to facilitate FOWT design; and collect real data from full and lab-scale experiments to validate the FOWT designs and computer tools. The program encourages the application of control co-design (CCD) methodologies that integrate all relevant engineering disciplines at the start of the design process, with feedback control and dynamic interaction principles as the primary drivers of the design. CCD methodologies enable designers to analyze the interactions of FOWTs’ aero-, hydro-, elastic-, electric-, economic-, and servo-system dynamics, and propose solutions that permit optimal FOWT designs not achievable otherwise.

Innovation Need:
FOWTs are currently designed to be large and heavy to replicate more familiar onshore wind turbine dynamics, maintain stability, and survive storms. However, this approach fundamentally limits how inexpensive FOWTs can ever become. Radically new designs that do not require a massive floating platform – applying the CCD approach of substituting mass by control systems – are needed. To design innovative, economically competitive FOWTs, researchers must overcome several significant technical barriers: insufficient current knowledge of how FOWT sub-system dynamics interact; insufficient computer tools for dynamic simulation; and a dearth of experimental data. ATLANTIS will address these technical barriers while exploring radically new FOWT design concepts that minimize mass and maximize productive rotor area to provide economical offshore wind power.

Potential Impact:
ATLANTIS projects will aim to develop new and potentially disruptive innovations in FOWT technology to enable a greater market share of offshore wind energy, ultimately strengthening and diversifying the array of domestic energy sources available to Americans.

Global Warming is B-U-N-K

ATLANTIS is B-U-N-K.

"California’s coming offshore wind boom faces big engineering hurdles"

quote The US is auctioning off its first floating offshore wind power sites this week, which could unlock a vast new source of clean electricity along the West Coast.

James Temple for MIT Technology Review; December 5, 2022.

"To receive divine spark from wind, Ohlone must pilgrimmage to Wind Spirit's abode" (centuries-old aphorism, translated from Muwekma Ohlone native speakers recollections)

quote The appeal of floating wind is obvious. Somewhere around 60 meters deep (nearly 200 feet) it becomes impractical for developers to build what are called fixed wind foundations. But the winds above deep waters far off the coast are often ideal: strong and consistent. Off Morro Bay and other potential California sites, the winds dip at midday but rise in the early evening, in nearly perfect sync with consumer demand—and in much the opposite pattern from the electricity generated by solar farms. Those characteristics will help the state’s grid operators draw more of their electricity from carbon-free sources through the evening, which will serve an increasingly crucial function as the California power sector moves off fossil fuels, says Alla Weinstein, chief executive of Trident Winds, which is a partner in the Castle Wind joint venture, which is bidding in the auction this week. The state’s climate laws will require 90% of its electricity to come from such resources by 2035. That same year, California will mandate that all new passenger vehicles sold in the state must be zero-emissions, placing growing demands on the grid.

It should be obvious to anyone that the sea levels are rising. They have found many submerged ancient ruins around the planet - at some point in time they were built on dry land. Unless of course the builders were some sort of unknown species.

Yes, all that water from the land-based glaciers has to go someplace. But what the global warmer people seem to forget is that the earth has gone through this cycle 5 times now. The earth is currently on it fifth warming cycle. Studies have shown that the earth has been free of ice at least 4 times before and frozen over 5 times now. We are still coming out of the 5th (Pleistocene) ice age.

"Scientists" do not currently understand what causes the ice ages, yet some how they know what causes the warming (apparently man)? The past warming ages are of various lengths to, so how can they say "unprecedented warming" is beyond me. We have no way to know what is normal as man has only existed for a tiny fraction of the age of the earth.

That being said, there is nothing wrong with looking at alternative forms of energy, but rush headfirst into things without proper study is just "sweeping the problem under the rug".

Do we know what environmental concerns will be in 30+ years from now with the current proposed solutions? Look at the whole plastic bag fiasco, BITD plastic bags were harled as the savior to the environment over paper - 30 years later people are calling them the bane of society. Same applies for this carbon capture and storage BS. Does anyone know what kind of problems we are creating by pumping all this stuff underground?

How much money did Al Gore make off his "carbon credits" company and did any of that money actually go towards global warming research? All these climate change zealots do is fly around the planet and have talks on how much money each country is going to give them to "combat the issue". Where is the accounting of where all this money goes? What can't they hold a Zoom meeting and save their carbon footprint? etc. etc. etc.
