From the article
Yeah the article is a little rosy and overstating things by using words like carbon free which obviously isn’t the case, but fta:
“Retrofitting a propeller plane with fuel cells and liquid-hydrogen tanks would result in a nearly 90 percent reduction in life-cycle emissions, compared to the original aircraft, according to the International Council on Clean Transportation (ICCT), a nonprofit think tank. That’s assuming the hydrogen is made using only renewable electricity —not with fossil fuels, the way the vast majority of hydrogen is produced today.”
Battery powered commercial airplanes are a pipe dream right now, batteries are just too heavy for anything practical with flight. Solid state batteries might reduce it some but probably not enough. We’ll still need some kind of mass long distance travel in the future. Once they’re able to scale up renewable energy sources even more, hydrogen made with those sources could become an important storage medium for getting that energy to power planes or other things where batteries are impractical. So it makes sense to at least be exploring these technologies.
Even for right now natural gas has a higher energy to co2 ratio than other types of fuels, so it’s possible there may even be a current efficiency boost, though I don’t know that off the top of my head.
If every new technology was attacked saying, well it’s not perfect right now so don’t even bother trying, we wouldn’t have electric cars or all sorts of other innovations. I agree with you on the article though, I hate when they say stuff like “look we have carbon free airplanes now” when obviously we don’t.
Taking these medicines in the forms they are found in nature is a horrible idea. Most of the plants they come from are poisonous because the therapeutic index of most of the drugs here are low, meaning the line between medicine and poison is very fine. Purifying the ingredient and allowing tight control of the dosage is the reason any of these are able to be used safely. Please don’t go around eating bits of foxglove or belladonna.
As you’ve seen, modern medicine is not shy about taking ingredients found in nature when they actually have a useful purpose in medicine, and enabling them to be actually used safely instead of taking some random unknown dosage of a potentially deadly drug and hoping for the best.
Except for fixing vitamin and mineral deficiencies, supplements are ineffective at best and dangerous at worst. They’re in desperate need of better regulation in the United States. They scam tons of people and get away with ridiculous claims like fighting dementia based on no evidence that would be totally illegal for any actual pharmaceutical company to claim, all while selling bottles of stuff with “proprietary formulas” or claiming to have plants that aren’t even in there when independent researchers look at them. All totally legal by the way, no requirement for ingredients listed on a supplement to reflect reality. Stay away if you value your health or your money. Not saying pharmaceutical companies are always shining beacons of beneficence here, obviously I have many problems with them as well, but they at least have some sort of regulated evidence base for the most part.
