"Simple" Over a billion cows are spread over the world. They eat over 10 billion kg of dry food each day. Estimating a 0.5% seaweed supplement, we're talking about 50 million kg of dry seaweed. Assuming a 90% water content, w

The fact that these glasses are clearly opaque remind me of Marty's reaction when he sees Doc's brown futuristic glasses in "Back to the Future". It does look a bit silly, but at the same time it looks useful, and not he

This articles points out that this is a very american-centric reality. If you cook your own food from basic ingredients there's almost no corn reaching you directly.

I'm not sure how prevalent this is around the world, but in my city we can register for produce baskets. In spring, I register on a website and I choose and pay in advance of the whole season a local farmer (less than 50 km away), who

I believe I've never actually eaten soy, and I rarely eat corn. I'm also pretty sure the amount of wheat humans eat is less than what we feed to poultry and livestock. The author seems to conflate the purpose of the "modern r

ToughSF wrote a nice blog post trying to design a functional Epstein drive. He ended up choosing Deuterium and Helium-3 fusion reactions (which create little neutrons but lots of protons) happening far behind the ship to prevent overheating

I don't get your point. What do you mean? How can the problem be CO2 emissions but not the source of those emissions? Of course if we want to solve the CO2 emission problem we have to reduce it at it's source?

Whales play a crucial part in natural iron fertilization of oceans, because they go deep underwater to eat a large amount of krill, which are iron-rich, and deject near the surface, because they need to breathe. Their dejections fertilize t

I'm curious to know if there's a limit to selecting plants cultivars. What should we optimize for? Vitamins, minerals, proteins, glucids, lipids, fibers or other macromolecules? Should we allow some sacrifice in taste, appearance,

No, because now you have two problems: police brutality and a coup. What's needed right now is a strong declaration, the creation of new country-wide laws forcing 3-years police training focused on violence de-escalation, an independen

I didn't know the space shuttle reused it's boosters. Apparently the two solid rocket boosters deployed parachutes after separation and were refurbished. Interesting! However the main booster could not be reused...

Lithium, beryllium and boron are rare because although they are produced by nuclear fusion, they are destroyed by other fusion reactions in the stars. This property is used to distinguish low mass stars and brown dwarfs. https://

Whales are a keystone species akin to wolves in Yellowstone, which prey on deer and allow a greater regeneration of plants. Whales also pump a large amount of nutrients to the surface because they eat deep water species and excrete near the

Whales fill their mouth wide open with water and spit it out through their baleens, a set of comb-like teeths that filter out everything smaller than a krill. Krills are 1-2 centimeters long and they feed on plankton much smaller than that,

Maybe this is a US-specific problem? I'm not American and the public education system is actually doing a great job in most developed countries.

It is bad because the value of human life (even people you don't like) is infinitely greater than material goods. A looted store can be repared, restocked, rebuilt. A dead human stays dead forever and yields a mountain of grief around

Maybe it would be easier, maybe not. My point is that we don't understand how the brain, intelligence, consciousness and emotions works. We try really hard to, in many different ways, and it's anything but easy. Every time artific

I fail to grasp how EV are "just like" releasing captured carbon in the atmosphere. Sure, building them has a carbon footprint, but so does an ICE vehicle, and over it's lifecycle an EV release a fraction of the carbon of a t

Well, if you produce fuel with the carbon you capture you still release it into the atmosphere, so there's no benefit there. Plus you have to add the carbon and the cost of developing/manufacturing/operating your insanely lar

Rowling has a strong french heritage and a degree in french literature. As a native french speaker, I can assure you that this is a deliberate play on both meanings: "Flight from death" because he is the one who escapes death, and

What happens to the energy used to rotate the device? Is it dissipated as heat before it reaches too far?

by Valgrim 7y ago
That depends. If the cost of production can be reduced with mass production, or the efficiency increased, so that it becomes energy positive, if the energy source required to make these windows is variable, for example by using any thermal

And why not avoid mentioning the source of the information altogether? "You were doing X." If the persons asks where the information comes from, just say "I pay attention."
