Disclaimer : the conversion of electricity → hydrogen is really poor (think 10%) so unless hydrogen is specifically needed for an application (eg : industry/ agriculture), using it as a way to transport energy or to power a car (once again, H2 →mechanical power is less efficient than electricity →mechanical power) is stupid (in 99.9% cases). Well done to those scientists, but i don’t wanna hear anything about hydrogen planes and all of that nonsense

It’s been bugging me for a while, isn’t it supposed to be their ?

Anybody got that shocked pikachu lying around. I think OP needs some

For the tractor part, some people have started using vertical solar panels which still shield vegetation form wind, excessive sun… But leave much more room for vehicles.

Given that :

A : agriphotovoltaism, can drive up most field yields because loads of places are now too dry and too hot in the summer. Solar panels block the excess sun and keep the moisture in the ground. Conversely, you can’t park more cars under solar panels.

B : your average field is much larger than a car park. So installing a solar power plant is more efficient in a field (less paperwork per square meter, spend more time building than moving material around…).

C : car parks are often surrounded by buildings which will block the sun. This doesn’t happen on most fields (which rarely have tall trees)

D : a car raming into your poles is bound to happen and you pretty much have to replace the whole pole. A cow ramming into your pole might happen, the pole won’t give a fuck.

E : installing solar panels above car park is a lot more expensive (taller infrastructure, need more space between poles so need chonkier poles, maintenance high up is way more costly, etc ) And solar panel companies usually work on a much tighter budget than say the petrol industry for exemple. So every dollar counts

Anyway, next time please do some research instead of posting a divisive post and spreading misconception ;)

Edit : as some others pointed out :

• destroying natural environments in order to put up solar panels is not okay. Which i totally agree with. That’s why I was talking of agriphotovoltaism specifically.
• if we get the opportunity, we might as well put up solar panels in both fields and cities. We shouldn’t paint it as an either/or situation because it risks dividing the pro solar population and i don’t need to explain why this is a bad idea

xkcd, two minutes physics, sebastian lague, peza’s work, CPG grey, branch education, …

Restrict the channels to be the good ones (3b1b, kurzgesagt, the gray cuber, lines that connect, twoswap etc) and put an adblocker on there and it just becomes an amazing resource for passive teaching

Yesn’t, it is much harder to compute shadows with a displacement map than with a mesh

Texture can be used as jargon for an image in 3d/2d rendering (more precisely, any 2D data can be a texture), but it can also be used to talk about the smaller scale detail of a surface (see textured plastic etc)

Depends, with homework, the goal is to learn, but with tests, it’s already less clear, a good teacher needs to know the level of it’s class in order to curate it’s teaching to their understanding. Moreover, some formation recruit based on grades and in this context, the point op is making is very relevant

I didn’t

Apologies if i’m wrong, isn’t it puritanism

Well til, anyways, i’m not telling you that articficial sweeteners are worse than sugar, i’m telling you that you might not want to take too much artificial sugar.

Be somewhat wary of artificial sweeteners, most of them are relatively new and so have unwanted side effects ore unknown side effect. (I geuss it’s like vaping : better than smoking but not great). Some known ones include : --cancer-- (edit : the cancer part is wrong aparently, see coment bellow) and obesity because you body cranks your calorie retention to the max (it sees a full can of something that tastes very much like sugar go in and no calories come out so it goes "wow, i’m really bad at extracting and storing energy. Let’s improve that ! And you get fucked next time you eat sugar) anyways, as with everything, be mindfull with consumption

I prefer myself some cosmere or some rivers of london

Either way you are doing good ദ്ദി√(^^^ᗜ^^ ),>

ദ്ദി√(^^^ᗜ^^ ),> it was much more about getting that xkcd in than contradicting you ;P

Oh and, there also zye. Almost forgot… He’s very new but very fun and intersting to watch.

Have fun conquering math
