There's an rule in the EU that says you can't feed the insects pork and then let those insects go on to be fed to pigs (same for beef and chicken). This is intended to prevent the transmission of diseases like Transmissible Spongiform Encephalopathies (like "mad cow disease"). As I understand it, this rule isn't because we have shown it's dangerous to do the pig -> insect -> pig chain but rather because we haven't shown that it's safe. Arnold van Huis and his team at Wageningen University are putting quite some energy researching the safety and lobbying the EU to change the rules based on the findings. At one of the talks those folks they said it's basically a black box of trying to get what kind of science the regulators will consider acceptable.
As you might guess, making sure the food waste you feed the insects doesn't have _any_ animal proteins in it is quite logistically challenging and so afaik nobody is doing that at a large scale.
I did quite a bit of research into the history of insects in the food system, especially in the Netherlands. While I was rooting for Ynsect and other big players to figure something good out I believe that it's a problem much better suited to a smaller scale (perhaps on the city level). Basically, have the food waste from various stores brought to a facility to be fed to insects and then let those insects be turned into whatever (pet food, fish food, trendy protein bars).
You'd have thought it wouldn't be the proteins in the input, but the prions in the output they would care about. They're remarkably resilient, it's not unreasonable to be cautious.

I think this is a weird wording.
I dont think you need to limit the ick factor to "Westerners"
There are an awful lot of people out there who would feel the "ick"
factor.
And even for some of those who do eat insects, they are specific insects,
form specific places, prepared in traditional ways.

Ain’t no way you want flying taxis in Manhattan. If two collide or one fails, you could kill dozens of people.
Maaaaybe instead of the tunnels and bridges, to increase throughput during rush hours, but even then we’re trying to have fewer vehicles in Manhattan, not more.
Also, I cannot imagine what it would be like to go through an intersection during the winter. You would be hit with a wall of cross-cutting wind tunneling down 50 blocks that no airborne device is going to handle well. Absolute nightmare.
I’m not an expert by any means, but one of the major impediments I would imagine to flying taxis carrying people is safety; there’s a _lot_ that has to be done before people board an airplane in terms of checks, paperwork, planning, etc.
The dream of “order a flying taxi on your phone and it takes you wherever you want in five minutes” isn’t really compatible with aviation safety culture (at least at the pilot level in the US). That’s not to say it can’t be done, but you probably need a lot of really good PR people to figure out how to say “we want to remove the safety controls from this so we can make money with it” and have people buy it.
aviation occupies a great deal of my attention, and there is a logic to everything that is done, based on actual provable, repeatable results.
anything involved in high volume passenger aviation has to pass reliability tests that will dry your eyes out just reading through the synopsis, nothing is making it to the PR stage.
I splain little bit, pick some fancy country full of rich people flying around, tell them that the US has just ripped the lid off airspace restrictions (again¹), and is now letting some kind of ubber drone thing loose , and quite litteraly instantly there will be calls for all flights going to the US to turn around as all insurance policys for commercial flights to the US will be null and void.
i don't think mountain rescue is asking for a better vehicle. traditional helicopters work.
flying taxi startups, drone companies, jetpack companies, and all the other fantastical flying startyps keep trying to say they have applications in mountain rescue, but i'm pretty sure that's providing a lot more benefit to the flying taxi startup's pitch deck than it is to any mountain rescue operation.
China calls it the low-altitude economy, and besides human transportation there is a lot that can be done. Personally, I believe that propeller-driven devices are too dangerous and noisy, but there might be innovations coming out of China that Europe can't
Lower noise, lower operating cost, lower purchase price, easier to pilot, more reliable (fewer parts), safer (redundancy), no emissions, faster time to air, configurable to requirements, etc.
It's hard to pick just one reason, but off the top of my head:
* Any failure tends to turn flying things into unguided missiles
* Noise is extremely hard to control -- I did an FAA helicopter discovery lesson, and oof
* Cities tend to have difficult to manage wind currents and hit-or-miss visibility. I was in a skyscraper across from one hit by a helicopter trying and failing to land in 2019 -- there's reasons for city no-fly zones
* Limited landing sites makes them highly situational in the first place, unless you want your streets to be helipads, which you don't
These are all fairly intrinsic and not mitigable. I can think of more issues more in the sticks, but you get the idea.
The wind in NYC is no joke. In brooklyn yesterday there were gusts so strong that car alarms were going off. In some apartment buildings, the handicap-accessible automatic doors simply cannot open into the wind.
One more reason is that it cannot actually solve the traffic problem that it claims to solve. It might be able to solve it for rich people when they are the only ones that can afford to travel by air, but if the cost ever comes down low enough for the masses to afford it, I don’t see any reason that congestion wouldn’t be as bad or worse than it is now. And to me it’s not a good investment to improve things just for rich people.
There’s just a lot more space when you can move in three dimensions, so I don’t think the congestion limitations of non-flying cars are likely to be replicated. IIUC (I’m no expert) that’s one of the most attractive features of flying VTOL vehicles.
You're bandwidth-limited on a sparse serialized landing site map no matter what, and you need far higher distance margins that will eat up basically all of the dimensional advantages.
If ground vehicles side-swipe, it's just an insurance claim. If flying vehicles sideswipe, it's a Problem(tm).
I am (usually) not willing to assume that the founders of highly technical startups would not consider something that I as an outsider would in the first 5 minutes of engaging with the topic.
That makes me skeptical of all of these (minus the wind currents in cities, that might have taken a little longer).
Founders can be chasing a dream and in doing so mesmerize investors. Or they capitalize on that same dream being the investor's. Even if it's not viable, it can still be really fun company to work for and/or earn money at. Even if there is a small lane for that sort of flying machine, the sheer number of companies purportedly working on something like that is suspect. Given the huge costs for development and certification, and the small number of vehicles that will really get deployed (certainly for the first so many years), there must be many that are never going to make their money back. I worked for a drone-adjacent company and now my LinkedIn is swamped with these startups.
Theranos was famously founded on pitches about blood testing from finger pricks that literally any phlebotomist and many people with a modest life science background could've told you were physically and statistically impossible on their face. You should be considerably less credulous toward startup grifters.
The reason why you (and everyone else) knows about Theranos is that it was unique, which serves as a bad signifier if you want to judge what is likely to happen with the next startup. Being in prison and losing billions of dollars is just not something most people get excited about.
I'm letting my mind wander and thinking what a French insect wrangler looks like. I'm kind of imagining a mix between French style, a cowboy hat, and lab gear.
I am baffled as to why cat food is labelled up as having "The great all-natural taste of beef and lamb that your cat loves!" because if my cat could naturally eat beef then that would be fucking terrifying, a 4kg cat that can eat a 600kg cow.
They should say "The great all-natural taste of mice and wasps that your cat loves!" based on observed behaviour.
Thanks to tools, I'm a far more capable hunter than my cat. It's trivial for a human of any size to kill a slow moving cow. It's very hard to imagine any scenario where a domestic cat would be capable of hurting a cow, let alone kill and eat it.
Why not? Have you tried? I have, must've been almost 30 years ago now, at Wageningen University. They taste quite well, if well prepared (they were). Insect burgers are also nice. I liked Damhert's insect burger [1]. People just think too much it looks like [2]
I would happily eat cricket protein if it were more scalably environmentally sustainable. I’m fine with milk, but cows aren’t helping our greenhouse sitchu.
Not to mention the issues with pea protein and lead content.
Oh my god eat some beans. Eat some tofu, eat some black-eyed peas, eat some green peas, eat some lentils, eat some northern beans, eat some lima beans, eat some chickpeas
Especially when you could have just fed them the grain directly:
…factory-scale insect production typically ends up relying on cereal by-products that are already usable as animal feed — meaning insect protein just adds an expensive extra step. For animal feed, the math simply wasn’t working.
It seems like their pet food business (where they were competing with input-intensive meat products) could genuinely have been sustainable, if they hadn't taken so much time to figure out that competing on livestock feed is hopeless.
This sounds like "draff", or distillery mash, where you get a huge lorryload of spent grain from brewing for very little money, which is still pretty damn nutritious for cows and sheep.
Better than letting it sit and rot, emitting massive amounts of methane in the process.
Not all agricultural animals are herbivores. Pigs and chickens are both omnivores. Also insects are probably good feed for some species of farmed fish.
As you might guess, making sure the food waste you feed the insects doesn't have _any_ animal proteins in it is quite logistically challenging and so afaik nobody is doing that at a large scale.
I did quite a bit of research into the history of insects in the food system, especially in the Netherlands.

How on earth did French taxpayers get roped into funding a moonshot startup whose entire goal was to make pet food out of insects..

I eagerly purchase insect/grub kibble for my dog - both fly and cricket based. Also a lot of vegetarian kibble, I am a vegetarian myself.

Surely nothing could go wrong feeding herbivorous animals a diet of insect protein...

Cat food contains insect protein, and cats are carnivores. They even catch and eat insects themselves.
In contrast, cats are being fed grains which they wouldn't naturally eat.
Moreover, insects are a cheap source of animal protein.
