In order for this to work, the electricity that drives the process would need to be generated in a manner that produces less CO2 than the reaction consumes. Which brings me back to what I said we should be trying to do a decade ago: building giant facilities in the deserts that use solar energy to convert atmospheric CO2 into hydrocarbons*. It's good to see someone's finally starting to work on it. :D ;)

It's also not a bad end-product itself ;) Less global warming, more alcoholic beverages - I could drink to that. :D


(and yes, I know - ethanol alone would make a lousy beverage)

Cheap, though! (maybe; hopefully)

But seriously, finding a way to economically denature the amount of ethanol involved could be a real problem if we actually decided to attempt this on a large scale.

I'm sure you're right. But by the time it becomes feasible on a large scale (if ever), maybe the hydrocarbon products will be possible. It's intriguing idea, solving two big problems at once.


On an entirely different note,

I read that the other day, inky. I guess I never really thought otherwise, for some reason. :scratch:

I always assumed her plane went down at sea and nothing would ever be recovered - there's an awful lot of ocean out there and a lot less land.
The Japanese prisoner theories, spy theories, etc, seem a little far-fetched.

Homeopathic Medicine Labels Now Must State Products Do Not Work

Quote:
The body has released an enforcement policy statement clarifying that homeopathic drugs are not exempt from rules that apply to other health products when it comes to claims of efficacy and should not be treated differently. In order for any claims in adverts or on packaging not to be ‘misleading’ to consumers it should be clearly communicated that they are based on theories developed in the 1700s and that there is a lack of evidence to back them up, the statement says.


The linked article has the link to the statement itself, which does indeed appear to require the disclaimer about the 1700s.

Actually, it probably won't, Jude. Just my guess.

On a related note, I read an interesting article in this month's National Geographic about the effects of faith on healing, pain management, etc. That includes the placebo effect, and the social aspects of faith on healing. If I can briefly summarize, it's that the prefrontal cortex associates healing/pain relief with certain social or environmental cues and communicates with other parts of the brain to release our own pain-relieving chemicals. One interesting example they gave was work that is being done with injured veterans. The pain management doctor works with the vets right away and finds something that they associate with positive memories, like peppermint candies (because Grandma gave them to them) or a certain smell (because it reminds them of a very happy memory). Those tangible items are given every time they're also given their pain meds. Eventually, just eating the candy or smelling the smell causes the release of their own, natural pain-relieving chemicals, meaning they're taking less pain meds (or even none). Pretty cool, huh?

Very cool.

My coworker, who is in the process of finding out exactly what kind of cancer he has :( :( :(, was telling me about the natural healers he has gone to. Given that he continues to work with doctors, I think it can only help.

On a happier note:

Edible Six-Pack Rings Feed, Rather Than Strangle, Wildlife

Quote:
Saltwater Brewery has partnered with the ad agency We Believers to create what they say is the first fully edible beer can packaging. Made from byproducts of the brewing process such as wheat and barley, their six-pack holders are fully biodegradable and completely digestible. Rather than ensnaring curious animals in a corset of litter, the company’s six-pack rings could serve as a satisfying snack. And if nothing is biting, the rings quickly decompose.

That is very cool, Frelga, about the edible six-pack rings!


(I am not happy to hear about your co-worker, though. :( )

Analysis of Neanderthal's teeth suggests use of herbal medicine

Quote:
Among those found at the El Sidrón site was a male who clearly suffered from an abscessed tooth. He also had an intestinal parasite that would have caused acute diarrhea.

In his plaque, researchers found traces of poplar, which contains salicylic acid, a form of which is the active ingredient found in Aspirin. They also found traces of a mould called penicillium, which helped produce the first antibiotic, penicillin.


Quote:
While the poplar isn't considered edible, the researchers said they can't prove definitively that the Neanderthal was ingesting it to relieve pain.

"But it seems like too much of a coincidence in that one individual," said Keith Dobney, who co-authored the study published today in Nature and is an adjunct professor at Simon Fraser University.


Other dietary info:

Quote:
The Neanderthals in Belgium consumed woolly rhinoceros and European wild sheep, along with wild mushrooms. The Neanderthals in Spain, on the other hand, seemed to sustain themselves on a purely vegetarian diet, eating pine nuts, moss, mushrooms and tree bark. This shows that Neanderthals from different regions had very different diets.

I think I would rather have lived in Belgium. Tree bark and moss casserole sounds terrible.

But safer than chasing a wooly rhinoceros.

Aside from learning about the diet of Neanderthals, I also just learned that there was such a thing as a woolly rhinocerous.

Since finding out that Birds evolved from dinosaurs I keep trying to imagine all dinosaurs with feathers. Is it just me?
