You just described every “Journalist “ and “Media outlet” in the world.It's funny (sad, really), how many publications repeat a bunch of BS, with no knowledge, research, or fact-checking.

This guy's vertical turbine is a piece of junk... way too many moving parts to survive for any length of time. It also wouldn't survive a winter with snow and ice building up on it.Have you seen this video yet?
I've watched quite a few videos and read a lot of books and PDFs on wind (as it's someday coming down the pipe for me), but wind is complicated, and there are lots of different ideas on how is best to convert wind to power.
Not sure if this (in the video) will wind up being any kind of holy-grail thing in the end, but it is the latest startup I've seen. In this case it is a VAWT (Vertical Axis Wind Turbine).. Generally it is considered that VAWTs are not as efficient as HAWTs, but who am I to say? I have no real hands on experience yet, just a bunch of textbook wannabe knowledge so far.
I do know that if I had a HAWT, I would want variable pitch blades for sure. As far as this VAWT style unit below in the video, it has a similar thing, it can be variable (open and close airflow to control itself, and variable magnet clearance generator tech) to protect it from overspeed, and control generator loading.
What I liked about the news reports was once again fusion power is only a few decades away. Though it would not surprise me that soon after I am dead from old age, or an irate woman, they solve all mankind's problems. So if the next generations are going to live in a perfect world good for them. Fat lot of good is does me.By the same people who declared a balanced budget in the U.S.?
"Scientists at the world’s largest nuclear-fusion facility have for the first time achieved the phenomenon known as ignition — creating a nuclear reaction that generates more energy than it consumes."
Depends on where you measure the energy it consumes ...
...
Yes, open circuit, these were during testing of the turbine in march. I have some videos, but cannot upload them here. This was with the 7 blade configuration on a temporary mount. these are snaps from a video. This was at 241 rpm from my notes. The turbine is a modified Fisher and Paykel 42 pole 4x3 wiring for 3 phase.would you mind sharing loads more details? pictures also go a long way.
and these numbers you state. are those open circuit measurements?
sooo many questions.
Any good experience with wind?
I'll respectfully offer that I've been watching Harmony for years and to the best I can tell they've yet to produce a working prototype that can make energy. I'm not saying that they are a scam but they check all of the boxes of every VAWT that has crashed and burned taking investors money with them and leaving the early adopters with nothing more than a piece of yard art.Not sure if this (in the video) will wind up being any kind of holy-grail thing in the end, but it is the latest startup I've seen.

RE: HarmonyThe problem with this is that why in the hell would they need to ask for funding?
Back to Future of Wind Energy
"I have noticed for a while that the same few "unusual" wind turbine designs seem to crop up over and over again as a "new" wind technology. This video is a critical look at these new wind products with guest Paul Gipe who has been monitoring the wind industry for over 40 years. I haven't referred to many by name here, but the advice in this video applies to all the ones I get frequently asked about: PowerPod, IceWind, Alpha311, Archimedes Screw, Lantern-type and any ducted, shrouded or vertical axis wind turbines. "
This guy's vertical turbine is a piece of junk... way too many moving parts to survive for any length of time. It also wouldn't survive a winter with snow and ice building up on it.
I've been researching wind turbines for about 5 years now. Here in Michigan, our 12kW solar array provides more power than we can use during the summer, but during the winter, its a horror show.. barely enough juice to run the kitchen let alone the entire house. Thing is, it's always windy here in the winter and putting up a wind turbine just for the 4 months we need it has been a dream of mine for a while.
In all my research, I've pretty much learned exactly what's been discussed in this thread.. Any small wind turbine you buy on the internet like Amazon is going to be a complete piece of crap, and if you want one that will actually work, its going to run $30k.
Then I found this on youtube.. The video I posted (below) is the condensed version, click his channel and you can watch every step of the build. This is a heavy duty wind turbine that will last a couple decades, and one that could be repaired if needed.. But as the saying goes, there's no free lunch... this guy put a boat load of work and effort into building this thing.
Yes. Devastated. But, I've just come across some great black stuff. "Coal" they call it. Bit smelly, but wow, it gives off some heat!Excited? This means all our work on solar has been wasted! ?
So I gather from this thread that Bergey or if you can find an old Jacobs are the only way to go.And it is used to make hydrogen! The new Green economy!
the sun seems to have an easy time sustaining net positive fusion ?
exercise for the reader...? ?"Easy" is maybe a bit of a strong word here... Are you considering the full supply chain? What about all the similar stars that have run out of fuel and/or catastrophically failed taking the surrounding region with them?
May I politly suggest that you, in the future, set your phone to record at a higher resolution? I can't make out any details on your multi meterYes, open circuit, these were during testing of the turbine in march. I have some videos, but cannot upload them here.

yes indeed, but I knew this from the get go.IMHO, wind is the money you're willing to throw away purely for the option to have another energy source, i.e., it matters more that you have the source than what you pay for it.
It will never break even. It will always be an ongoing expense.
