It really doesn't seem like it could pencil out, as it carries only one blade at a time, that's three trips for each turbine - and most windfarms would have more than one. But I guess they think it does. Perhaps they can also deliver to offshore farms, which already have contracts. I know there is a shortage of the specialized ships to float their huge blades out.

Also, I hope they've done their homework on NIMBY pushback on land which is pretty effective against wind farms even with regular sized turbines.


Looks like they load 2 blades at a time. Check out the image on their site. https://radia.com/windrunner


The image 3/4 down the page directly under "Specifications" with the transparency slider shows the rear of the plane only fitting the narrow tip end.

It can fit multiple smaller blades but only 1 very large blade.


Also, wind farms with giant blades tend not to be built close to airports, for some obscure reason.


Depends on your definition of "close". There is a wind farm pretty close to the Berlin airport, but certainly some miles away.


Obviously because they put airports where there isn't wind.


Well, the photos show at least two blades in there, top to tail.


The energy use is the issue because fossil fuels supply the heat for the thermochemistry (like with most industrial processes). But direct solar heat could be used instead - this heat is supplied by concentrated solar thermal in a novel process

Re 'Why these crap journals even exist is a mystery to me.' Don't journals make money by charging academics to read the whole paper?


And by charging the authors to publish the paper in the first place. Although I think a lot of the money both ways comes from universities and other organisations that pay for publication costs and have deals with publishers.

Thank god for CS's culture of pre-prints on arXiv.


Yes, that's got to be part of the explanation. What's not clear to me is why anyone gets professional credit (e.g., tenure) for publishing in a journal that is obviously bad.


The answer to your question is just part of the whole sad story...

Promotion committees (hopefully!) know which journals or publications are low quality. If they are unfamiliar, they generally don't have time (or inclination) to verify the paper(s) or publication itself. Especially true when it's a slightly different sub-field than their own. So it often comes down to a simple count of pubs. That's usually all the credit they need!


His use of "he" or "his" research was a bit dated looking... More natural to say "they" presented a paper and "their" paper didn't pass muster or whatever


Yes, there's lots of houses in suburbs with empty bedrooms. If there was an incentive for boomers to rent rooms in their houses like in the 1920s. But that is risky for the boomers.

How about to reduce risk, but reward lucky ownwes, a lot of houses too big for aging boomers, could have incentive payments to sell to HUD to convert into rooming houses, with lockable bedrooms rented separately, and the shared kitchens and bathrooms cleaned by HUD, and quick evictions for any troublesome renters. So more like renting at a YMCA or backpackers' hostel, ideal for the working poor.


The Ports of Los Angeles require decarbonization, and so this is not required to go great distance, but rather to spend a day moving containers around at the port.


Distance isn't the only issue. Nobody needs that kind of power in a truck to get around in.

But short haul and heavy duty like in a mine, this would be very handy.


Recent documentary where those heavy CAT loaders in Sweden mines are electric: https://youtu.be/V5aDnIfBCKA?si=aQevXe13IjjFkgRQ


I can see EV for next-gen mining equipment, the sort of behemoth that the wheels alone dwarf a man standing next to one - and still needded for mining new climate tech energy likel lithium, copper, silicon - but jeez, just some truck?


Not quite a behemoth but there is already a 120 ton mining EV:

I thought mining equipment like that already was electric?

1978: https://en.wikipedia.org/wiki/Bagger_288

> Gross power: 16.56 megawatts of externally supplied electricity


EV for mining is already a big deal: you don't want to run diesel equipment underground in an enclosed space.

The optimisation for mining would be replacing more of the surface diesel generators with solar + batteries as a logistics optimisation.



California runs on 100% renewables for 4.8 months each year in a sense too.

It has 40% renewables last time I checked I think in 2019.

If you assign that to what percent of the annual use, that is the equivalent of everything from Jan 1st-April 24ish California is runing on 100% renewables.


Uruguay's electricity was 100% renewable for the last four months, not four months in the last 12 months. In the last 12 months they were over 90%.


Cottage industries from at least the time of Queen Elizabeth did have women working though. It was just that there were no factories until the industrial revolution, so that industrial activity remained in the home "the cottage", for both husbands and wives.
