A team of scientists has figured out how to convert planet-warming carbon dioxide into a harmless powdery fuel that could be converted into clean electricity
Plants have a fixed life cycle. Unless we found a way to make all plants like bamboo, capable of growing at extreme speed (there are species of bamboo you can observe groing in real time with your naked eye), plants take a set time to absorb a set amount of CO2.
The promise here is to syphon CO2 straight from the atmosphere into a solid state we can store, reuse or dispose of, safely.
Pollen isnt sperm. Pollen is the heavily regressed secondary generation. All plants follow alternate generations.
Pollen is the male semiclonal offspring of a dominant angiosperm form. The female lives within the heart of flowers, where they wait for pollen males to arrive and enseminate them.
And, yes, the definition of powder is a dry solid that sheers into fine particles. Pollen isnt a dry solid, its a bunch of organisms that are just very small. You could turn pollen into powder by killing, crushing, and drying it. But thats the same as sawdust.
