Yes, or maybe more accurately - we are the American equivalent of Formula SAE Germany. The German teams are significantly more advanced and better funded, with some of the teams running custom built electric inhub motors (something that's unheard of here in the US)
I am currently on San Jose States Formula SAE team - we merged our electric and combustion teams last year to go all electric since it's where the stiffest competition exists.
If we could secure sponsorships we'd love to take our car to Germany!
Formula Student Germany has been leading the rules for the electric and driverless since their inception. There is a meeting every few years at the FSG event to align some rules for the different global student competitions. There was one this year again. (Source: I'm in the timekeeping team/organisation, to the driverless cars: please stop destroying our gear)
I didn't know San Jose State had enough money to run an team like this.
Unless I'm mistaken, aren't Formula teams expensive? the cars get rebuilt often, I imagine its no different with electric (less to rebuild, perhaps, but anything mechanical would need to be)
This is not an accurate take. It does not require some great expertise to identify edible mushrooms, and in cultures where mushroom consumption has been common for hundreds of years (such as Russia), basic identification techniques are well known.
There are some edible mushrooms with poisonous look alikes - there are plenty other edible mushrooms without those deadly cousins. If this gentleman had made it 70+ years without issue, it is rather unlikely he would have some issue now.
As the saying goes: there are old foragers and bold foragers, but there are not old and bold foragers.
From what I understand, one of the big bird issues with turbines is that birds of prey like hawks, eagles, and falcons don't generally look forward but down as they scout for prey, and thus are likely to fly into turbine blades. I believe some turbines have cameras systems to detect birds in the vicinity of the blades and either make a noise to alert the bird or maybe even bring the turbine to a halt.
This is really only an issue for large scale installations though, obviously wouldn't apply to low lying roof installations.
The bearded vulture is one of Europe's largest birds, it rarely comes to The Netherlands, living mainly in Spain and France. When it does comes to The Netherlands, about once every 3 years, it'll be a national news item as it's quite a spectacular bird. Last year one came, and not a week later it was found dead under a wind turbine.
That bird is not just a statistic, it was the single bird of one particular species in our country, and it flew into one of the few wind turbines we have.
I'm 100% for wind turbines, I think it's a magnificent sight every time I cross the afsluitdijk seeing them rise from the mists providing us with clean future proof energy. But the sort of stupidity that drives an engineer to say only 1 in 10000 bird deaths is due to wind turbines, without asking why or how or what bird is going to be the end of us all one day.
Afsluit = "close off". Dijk = "dike" (pronounced the same too). It's a 20 mile long dike we've built that closes off what used to be the South Sea from the North Sea, turning it into a big lake that's called the IJsselmeer.
It's all the QWERTY home-row letters making it look that way, I think. Does look a lot like a quick slam of the fingers on the keyboard to generate a "random" string.
Are you really 100% for wind turbines then?? Is there a way to make them less harmful to birds? Maybe keeping the speed lower? Maybe putting up some more static installations that keep birds away? (Like, say, bright trailers on the fan blades? Is that a real idea?)
Yeah there's research being done on multiple solutions. One of them is painting one of the blades a different color which helps somehow. I don't see how there couldn't be a technical solution, it's not like these turbines are on a tight budget. It could be as complex as having autonomous drones chase away birds if nothing else works.
True. About 50.000 birds die due to windmills per year in The Netherlands, so according to this stat we should have 500M birds. So the odds of it killing a specific bird is roughly 50.000/500M=0.01% chance. So we'd expect it to happen once every 10.000 years. Guess we got unlucky last year..
But the statistics can also be deceiving if presented like that, just like you said if people don’t stop and think about which specific birds they kill.
For example let’s say windmills kill 100,000 birds a year and let’s say that is 0.1% of all birds. That looks acceptable. Well 90,000 of those might be seagulls and represent perhaps 1% of seagulls and 9,000 might be eagles representing perhaps 50% of all eagles.
I pulled these numbers out of a hat but all that to say we shouldn’t lump rare birds together with abundant ones.
On this particular vulture (my apologies for looking the way the story is told makes it sound like one of the "They can’t have cows feed under those because it, it causes some kind of birth defects. This is what my sister who has cattle was telling me." ( https://www.marketplace.org/shows/how-we-survive/white-gold/... ))...
> With certain bird populations like the Bearded Vulture growing, birds can disperse in unusual habitats, and it is critical to find solutions to mitigate such threats. Operators need to develop shut down on demand processes and be willing to cooperate with conservationists to avoid accidents and help save birds. Furthermore, wind farms should implement mitigation measures to help prevent collisions such as equipping deterrent devices and even painting a single wind turbine blade black as a recent study suggests, however, more research is necessary to determine the effectiveness of this anti-collision measure. To safeguard biodiversity, conservationist should work alongside the energy sector to find solutions and prevent such accidents.
> Now comes research in the journal Biological Conservation on an automated system that scans the skies and can turn off a windmill if a bald or golden eagle is headed toward a deadly collision. Researchers from The Peregrine Fund, Western EcoSystems Technology and American Wind Wildlife Institute used human observers and photographs to see how well the camera-based monitoring system called IdentiFlight could detect, classify and track birds.
> The IdentiFlight system detected 96% of birds detected by observers and 562% more birds than observers. It's not perfect; the system misclassified nine of 149 eagles, for a false negative rate of 6%., with a false positive rate of 28% for misclassifying 278 of 1,013 eagles. Birds were classified as eagles by the system at a median distance of 793 meters (about a half a mile), and detected and classified in less than half a second.
The aero packages for these vehicles create a pretty significant amount of downforce at relatively low speeds - for example, our car last season produced ~140 lbs of downforce at 35 mph.
Edit - A lot of that comes from the rear wing though, which the green team didnt run for this particular event.
Although the other comments are correct about the 30mph optimization for the aero package, this car uses active underbody aero (aka, fans) to create additional downforce even when at a standstill. See the recent runs of the Speirling at Goodwood festival of speed to see a purpose built "fan car" in action.
Interestingly, this setup wouldn't be allowed due to rules in Formula SAE in the US but is legal in the german competition cause those teams are just built different.
Edit - Quick plug! If anyone is interested in supporting FSAE and the awesome engineering that goes into these cars, I am a member of the San Jose State team and our aero team is in need of HPC access to run their CFD simulations. My email is in my profile. Cheers.
I learned that the two of them were housemates for a period of time while taking a mycology class from Alan - can you imagine being a fly on the wall in that place? What a colorful group.
I have to say I think it's quite possible and comical that the professor interpreted your work on two of the three questions as additional evidence that you did know it should be an "and", since I would guess relatively few students would attempt any more than _one_ permutation if the assignment only asked for one.
But what did the other students the class do? If almost everyone in the class did only one, the professor would have to give almost the entire class 33% for a mistake he made.
Looking back, I should have asked around. The job scheduler was one of several options so not everybody picked it. Still, somebody else must have.
The professor actually did relent and gave me a good (not perfect, but good) grade. Then he judged me extremely harshly on the final exam so I ended up with a B in the course anyway.
Did you know that hemp was not used in Dr. Bronners soaps until the 90s?
I think it's well know that Emmanuel Bronner suffered from some mental illnesses - the man lost his family to the holocaust and was sent to a mental asylum upon arriving in America. Life was not necessarily kind to him but he seemed to do alright with the cards he was dealt.
I know when I first learned about the soap, I had a similar sentiment as you. As I have learned more about the history of Dr. Bronners, I have come to see that it is hard for me to imagine some of the trials that the generations before us have faced.
Could you clarify by what you mean as "it wasn't very nice"?
I've been using bronners for a decade and have recommended it to more people than I could count. I've never had anyone tell me they downright disliked the soap - with the exception of peppermint, some folks don't like the chilling sensation.
Follow the instructions on the bottle for dilution as well, makes like easier and spreads out the soap.
Like sibling commenter said, it leaves everything on your body very dry.
Your hair gets that stiff feeling that shampoo doesn’t leave you with. I think it was the mint one I got, as recommended, and it left strong sensation on my balls - the kind you can’t tell if it is burning or freezing. And generally skin dry.
So what exactly does it do that the cheapest store brand bar or liquid soap doesn’t? It’s obviously full of residue given it’s scented, and even if it wasn’t full of non soapy things you’d still need to use body lotion and conditioner afterwards to not feel completely dried out.
Bronners cleans dirt and washes away sweat and grease, sure. But I’ve never encountered a soap or detergent in a super market that didn’t.
The cheapest liquid hand washing soap leaves your skin feeling softer and just as clean and just as scented as Bronners. Although I’m not really sure why being scented is a selling point.
Personally I can’t see why you shouldn’t go for a no perfume, certified safe for people with astma and allergies and certified environmentally friendly. In some markets (like Denmark) even the store brands has these certificates and you can scent yourself with the perfume or cologne of your choice instead of having a mix of cologne, body wash and shampoo fight it out.
Not OP but I have tried to get along with it several times and every time, it dried my skin out so bad that I would itch, crack, and bleed. Leaves everything "squeaking" like Ivory soap, which I also don't like.
I will use it for housekeeping but I don't let it near my body anymore.
Everybody has different needs, so I can respect that it's not a perfect soap for all people.
That being said - are you diluting it or using it straight? I usually dilute 4 parts water to 1 part soap for handwashing / showering. Also, the Eucalyptus scent was harsher on my skin than others - I prefer the unscented, almond, or peppermint varieties.
