The Eurasian Steppe? Anywhere that water was a potential constraint it was used as the critical controlling mechanism by tribes, chiefs and governments. This ranged from war over water sources, governmental control of wells and oasis points, to mechanisms of forced corvee labor or taxation based on water supply volume. Water has only been free in social or fiscal terms in places where it was present in such abundance that it was of no value.

Sure but my comment was in the context of the North American market. In that situation there are large windy areas on land with little or no population which are ‘low hanging fruit’ and which are the incumbent method of wind generation. Europe is a different place with different population densities and sea conditions. Europe also mostly lacks good quality land based wind resources making the financial calculus quite different even in the absence of shared land use issues. with respect to capital, it’s not just about getting access to it, but being able to use it efficiently. I could dump a billion dollar/euro grant for wind energy on you tomorrow and you would have to start from scratch figuring out how to use it. Pre existing large organizations can efficiently use the money immediately without excess delays caused by constructing an organization and facilities to utilize the funds.

Any portion of the old testament dealing with water is a good example. If you aren't familiar with biblical sources, feel free to look at different ones - I merely included it because I thought you would already have them near in mind. Here is a partial list of how water plays a pivotal historical role in the region, as taken from the bible. https://en.wikipedia.org/wiki/Wells_in_the_Bible Washing clothes? sure, free use - but that's an incidental use of water. The main use of water then and now is in agriculture - to secure a food supply. That was, is and has been strictly a state controlled affair. American western plains - no cash exchanges took place (since they didn't have it) but tribes could and did fight over water rights. Especially on the southern plains and in the southwest, access to good quality water sources was the key to success. The Comanche guaranteed this by killing anyone who used 'their' water without permission, and the pueblo indians settled at any useful sources and 'blocked out' competitors by preventing them from getting physical access. Without money or markets does not mean 'without control or accountability' The Inca constructed a series of terraced farmlands in order to capture rain and snow melt from higher elevations for agricultural purposes. These were constructed with corvee labor, where taxes are paid for in labor to the state rather than cash. the resulting farmland was then apportioned out to citzens for use, and the produce collected by the state/temples. The food supply was controlled by the water supply, and the state controlled both ends of the system. I have never heard of the movie you mentioned. The hypothetical techniques to create or suppress rain aren't really relevant, since they have not proven very effective either in terms of volume of water produced, or return on levels of effort employed. Control of water has been a method of organizing and controlling people since long before money was invented - money is merely a method of accounting for and measuring value, but in places without large volumes of rainfall, water IS one of the sources of value, so the intermediary of money was not required for it to be useful. It has the additional benefits of being easily measurable and easy to account for in volumes which matter (i.e. volumes large enough to produce usable volumes of food with) Edited July 28, 2021 by Eric Gagen 1 1 Quote Share this post Link to post Share on other sites

They don’t need grants or ‘seed money’ they are commercial profitable organizations pulling in steady profits who are listed on major stock exchanges. They site, plan and execute major wind projects on land on a routine basis. even if offshore wind is theoretically more capital efficient, at least in the US any organization which wanted to get into it would have to build up that knowledge and competency which the land based organizations already have. Until they do their improved capital efficiency is in theory only because they will not in fact be more capital efficient. It’s liable to take them 3-5 years or so of steady investment with sub par returns on capital to close the organizational gaps required to be efficient offshore wind energy organizations. This is why only the largest of companies can do it - they need to have large and stable sources of cash flow to effectively subsidize their offshore wind segment until it is capital competitive on its own. Also the turnaround time on capital for offshore projects tends to be longer than on land. Until the project is up and running and cash flow positive the capital is tied up and unavailable for redeployment. Only large companies with lots of capital/borrowing capability can afford to do projects of this nature. 1 Quote Share this post Link to post Share on other sites

The US does have a lot of land this is true but you're never going to building wind turbines on the scale of the offshore ones being built elsewhere, as who wants a 860ft tall wind turbine farm near them??? That nearly 3X the height of The Statue Of Liberty and dozens of them. Offshore does allow this. Floating offshore maybe the answer but this isnt economic at present IMHO. That being said you can of course build smaller scale onshore. Quote Share this post Link to post Share on other sites

This may surprise you if you haven’t been, to the US but you can build wind turbine farms on land here (not dozens but hundreds of them) and the entire project be sited out of sight of the nearest human habitation. There are dozens of projects with over 50 windmills per project like that on land here. Not 860 ft tall though - there may be a feet/meters translation issue here - most of them are ~ 250-300 feet tall, so 70-85 meters. Any offshore project looking at an overall height of 860 ft is either theoretical plans for the future or is measuring total height from the sea floor, and not height over the water surface.

Nope - I hadn't seen them - the largest ones I had seen are the big land based ones in the 300-450 ft tall range. As I noted, there isn't really any offshore wind development in the US yet, so this sort of equipment isn't here. I was fully aware that the sea based stuff tends to be larger, but hadn't really been keeping up with it, since it seems unlikely that there will be any significant volume of sea based wind power in the US any time soon. You probably couldn't install them efficiently on land, as the sea based installation technique is (very loosely) based on partially sinking the column the turbine is based on, then bringing it back to operating height, and/or the use of massive floating cranes which exceed the size of those which can be moved around on land. Based on my experience with offshore facility work from the oil and gas industry, it would be wonderful for me personally if these were to take off in the US it just isn't happening on a large scale soon, although there may be some off the northeast coast before long.

I do think there's scope for offshore wind on the US east coast It may well be that floating offshore wind becomes a lot more economic as it is a very new industry. I'm not an engineer so I'd be interested from any of you guys that are engineers what the viability is of building floating offshore wind turbines on the scale of the Haliade X and what engineering challenges there are in trying to do so.

No mooring required for the types of operations being considered in the US east coast - in general these are expected to be in relatively shallow waters, where a variety of structures fixed to the seafloor can be used. This is similar to those in Europe now. There are a variety of deepwater installation options being considered, but it's not yet clear which ones will be the best types, and there will probably be different optimal ones in areas with different sea state potentials and different undersea soil/rock conditions. These are all 'solved' problems from the deepwater oil and gas industry which easily port over to wind turbines. Even the construction techniques are interchangeable, since the undersea support systems are consistently constructed seperately from the 'topsides' and then mated up later. This means they are fully modular and can be set up plug and play as needed. 1 1 Quote Share this post Link to post Share on other sites

RichieRich216 + 454 RK July 30, 2021 On another Ode to green technology….. Wait for it…… The founder of the much-hyped electric truck manufacturer Nikola Corp. NKLA, -15.22% has been charged with lying to investors about the supposed technological breakthroughs the company had achieved in order to drive up its stock price, federal prosecutors announced Thursday. Trevor Milton, 39, is accused of claiming that his company had successfully manufactured working prototypes of electric trucks and pickup trucks that would turn the industry on its head, when he had, in fact, never built anything. “At the bottom, this a very simple case: Milton told lies to generate popular demand for his stock,” said Audrey Strauss,, the U.S. Attorney for the Southern District of New York.

Milton resigned from Nikola in September as it emerged that the justice department had opened a probe into the startup and its founder over possible false claims. Milton has previously tweeted that he intended to defend himself against “false allegations.” Prosecutors said Milton was taken into custody Thursday in Manhattan and was later released on a $100 million bond. His attorney, Marc Mukasey, said in an email: “Trevor Milton is innocent. He’s been wrongfully accused after a faulty and incomplete investigation. He will be exonerated after trial.” In a statement, Nikola said that the indictment was against Milton and not the company, and noted that he had not been involved in the business since last year. “Nikola has cooperated with the government throughout the course of its inquiry. We remain committed to our previously announced milestones and timelines and are focused on delivering Nikola Tre battery-electric trucks later this year from the company’s manufacturing facilities,” the statement read. In the indictment, federal prosecutors said Milton had for years overinflated the technological developments the company had achieved, claiming it had built working prototypes of its Nikola One truck and Badger pickup truck out of parts the company had fully manufactured on its own. To make it appear the truck prototype was driving, it was towed to the top of a hill and then rolled down to the bottom, prosecutors said. Prosecutors said that, in fact, the prototypes that had been unveiled didn’t function and were Frankenstein monsters cobbled together from parts from other vehicles. At public events, the vehicles were allegedly towed into position and were powered by plugs leading from hidden wall sockets.

To make it appear the truck was driving, it was towed to the top of a hill and then rolled down to the bottom, according to the indictment.

SUBSCRIBE NOW: $1 FOR 4 WEEKS Milton allegedly repeatedly said publicly that the prototypes were fully operational and overstated the number of pre-orders the company had received. Non-traditional IPO In June 2020, the company went public via a blank-check company, or a SPAC, called VectoIQ Acquisiton. A spokesperson for VectoIQ declined to comment. Prosecutors said because the company didn’t go public through a traditional IPO, Milton wasn’t bound by the traditional “quiet period” rulings following the listing, and was able to make outlandish public claims on social media about the company’s success in order to drive up the stock price by attracting retail investors. “Among the retail investors who ultimately invested in Nikola were investors who had no prior experience in the stock market and had begun trading during the COVID-19 pandemic to replace or supplement lost income or to occupy their time while in lockdown,” the indictment read. Prosecutors said in the initial period following Nikola starting to trade publicly, the value of Milton’s shares shot up by $7 billion. After it emerged the company was under investigation, shares tanked causing many retail investors to lose tens and even hundreds of thousands of dollars, prosecutors said. In some cases, some investors lost substantial portions of their retirement savings, they said. The Securities and Exchange Commission is running a parallel civil complaint. “Having chosen to promote Nikola through social media, Milton was obligated under the securities laws to communicate completely, accurately and truthfully,” Gurbir Grewal, director of the SEC’s Division of Enforcement, said in a statement Thursday. “That obligation exists for all public company officials, even those whose companies have only recently entered the public markets through SPAC transactions.” The thing’s they will do for green… More like GREED, All part of the great green energy Ponzi Scam. 1 Quote Share this post Link to post Share on other sites
