Is anyone saving cans? To what end? Is the plan to resell them regularly for scrap or keep them to trade for food if money losses it's value?
I thought that some cars have aluminum engine blocks? you could get a lot more scrap from just one old junker. Maybe these have already all been scraped?
Burn aluminum!!

I don't feel like deleting this, but this is probably a bad idea for 10 different reasons. The main reason is that aluminum wool is probably not any easier to light then aluminum foil. But still, it would be fun to play with some aluminum wool and uncoated steel wool...I wrote:Cool aluminum burner idea!
I wonder how small that could be made. Maybe something like a miniature aluminum wool burner could perform well as a tent heater or pocket heater. No carbon monoxide... But as a small heater it would probably run into the same problem steel wool does, that the surface burns but much of the steel fibers core does not. It would be interesting to try though. I think the problem with incomplete steel wool burning could be solved with a continuous airflow from a small adjustable rate fan. Something I've been thinking about anyway...

Every year, the billions of metric tons of carbon dioxide (CO2) we release into the atmosphere add to the growing threat of climate change. But what if we could simply recycle all that wasted CO2and turn it into something useful?By adding electricity, water, and a variety of catalysts, scientists can reduce CO2 into short molecules such as carbon monoxide and methane, which they can then combine to form more complex hydrocarbon fuels like butane. Now, researchers think we could be on the cusp of a CO2-recycling revolution, which would capture CO2 from power plants—and maybe even directly from the atmosphere—and convert it into these fuels at scale, they report today in Joule. Science talked with one of the study’s authors, materials scientists and graduate student Phil De Luna at the University of Toronto in Canada, about how CO2 recycling works—and what the future holds for these
