Hi Pierre:
Wait, I “dwell”? On the relevant facts? “Aspects that hardly interest you”? Oh, you mean all the aspects that determine how the stupid thing can possibly work? The aspects that real wind people see at a glance as typical newbie nonsense? Those aspects?
Well, your endlessly-self-conflicting assertions convey at least an ongoing curiosity and interest in airborne versions of wind energy, but the fact remains that any conversation about wind energy with people with zero experience with real working wind energy systems is always extremely limited, and always fraught with the same old typical newbie errors.
In this case you see one more “press-release breakthrough” about some supposed “innovation” in turbine design, lighter than necessary, developed by wind newbies who are unfamiliar with all the well-established design drivers for working wind turbines that can last even a few hours in a strong wind, let alone decades, and here we are, back “discussing” the latest offerings of a press-release describing an innocently hopeful prototype by the latest “Professor Crackpot” who is under mind control, afflicted with “global warming derangement syndrome” thinking that logic, experience, and facts won’t matter, just the good professor’s typical newbie gut instinct with all the typical beginner mistakes included, such as “it starts at low windspeeds!” (like no real wind people ever thought of that), and “it’s lighter weight” as though their inexperience in turbine design and manufacturing are somehow an “advantage” when in reality, this mere prototype would likely demonstrate once again, for the thousandth time, how strong wind turbines need to be to survive, how heavy the generator must be to handle sustained high winds, etc., while all these simple facts are lost on the perpetual newbie crowd.
Ome day you are pronouncing AWE as a failed dead-end, with no hope of success, ever, by any means, going on to say the forums are a waste of time and you are never going to post again, and a few days later you are back on the latest forum, defending “Professor Crackpot’s” latest offering, saying it belongs in the sky!
OK I’ve got one for you Pierre:
5000W Vertical Wind Turbine 12V Small Windmill Free Energy 220V Household Farm | eBay
There you go: a drag-based vertical-axis plastic toy turbine, with less than one square meter of swept area, claiming 5000 Watts in the title, then 3000 Watts as you read on, then less and less wattage as you see the tables in the description, while any “real wind person” (a term you have protested in the past) would ignore or just consider as humor.
You recently pointed me to a discussion of a drag-based, roof-mounted, vertical-axis turbine on Linked-in that included “real wind people” and you could see the result: Everybody in the discussion told the V-A advocate who had started the discussion that he was 100% full of hot air and knew nothing about the subject matter and was lying. Nobody defended him. Everybody knew the deal. Everybody but the V-A turbine seller himself, who as we noticed, wrote almost identically to that person we often bring up here, but who is no longer allowed to post here. It only illustrates that some people have good writing skills, but zero engineering, logic, or math comprehension.
Anyway, sure it would be nice to suddenly have a lighter weight turbine to hang from a kite, but as always, the tradeoffs between instantaneous power output capacity, and the ability to maintain high output for hours or days on end, do not change just because a know-nothing “author” or “journalist” stumbles across the latest “Professor Crackpot” press-release “breakthrough”.
These discussions would not even take place in a venue of 100% experienced wind energy people. It’s only perpetual newbies with their feet firmly dug in against ever learning or knowing anything about wind energy who can endlessly go on repeating the lies of other wind newbies. Real wind people just laugh at the absurdity of it all.
Anyway, you have asked me in the past why I think no “real wind people” have ever been involved with AWE. Well, one reason is that they understand the subject matter, what works and what doesn’t, and another is they have experience in running real wind systems so they know what survives and what fails, how much generator weight it takes to make a certain amount of steady-state power, how wind energy needs to be “set-it-and-forget-it”, and how any wear points are problematic for longevity and must be eliminated to the extent possible. Awe people instead focus on whether people will spend their days flying AWE systems “over New York City”, climbing around on ropes at thousand of feet in the air over traffic, piloting kites for zero pay, but instead “for the honor”… - yes this was actually a real discussion by that same idiot on these same forums! Well, I hate to break the news, but “real wind people” are just a liitle more aware of reality than that…
Hope that helps!
