Hey. Let me walk you through the Donnelly nut spacing and crack system rim-riding rip configuration. Using a field of half-C sprats, and brass-fitted nickel slits, our bracketed caps, and splay-flexed brace columns vent dampers to dampening

Woah! I had no idea something like this would be so far along. It seems like they're on the right track. I think the key is to keep scope creep to a minimum. As soon as someone tries to add DRM, for instance, the whole effort will g

Maybe a dumb idea, but I wonder if there's a future in cryptographically signing videos in order to prove provenance. I'm imagining a G7 meeting, for instance, where each participant signs the video before it's released. Fu

I see what you're saying-- Bootstrapping a green economy does, almost by definition, require the use of fossil fuels. I think the easier way to look at it, though, isn't the upfront cost of the transition, but the outcomes that ar

The question of whether or not this type of intervention will be necessary comes down to the specifics of various climate tipping points. There's evidence that we've already crossed a tipping point with regards to methane release

I wish there were better options for inexpensive, miniaturized heat pumps. I can think of all sorts of applications where it'd useful to have them. Plunge pools, hot tubs, trailers, greenhouses, dog houses, etc.

Peltier fridges definitely exist, although the poor efficiency means that they're best suited for small capacity. Here's an example: https://www.amazon.com/dp/B07KZLJ7PB

The Toyota Mirai platform is impressive, although it is still heavily subsidized. I guess my question was about the cells themselves, though, and less about H2 production / storage. I’m reading that the newer fuel cells have much less

Can anyone here speak to the practical aspects of making fuel cells work at this scale? What exactly needs to change to gets the costs more in line with ICE vehicles?

Geoengineering is a unique prospect in that it's inexpensive-- Cheap enough that a couple of billionaires could pay for it if they wanted. In terms of interventions, it's a much easier pill to swallow than something in the trilli

It's not a foregone conclusion that we're doomed to a life of accelerating climate change. We could deploy solar geoengineering to see us through the transition to renewables. Then, as fossil sources are retired and direct air c

No negativity taken. These are complex systems. Any solutions involving forestry should be heavily scrutinized.

Note that most of the carbon offsets offered by airlines are forestry-related. Any time you see offsets for less than $50/ton, proceed with an abundance of caution. I do think the general state of offsets is improving. There are more

There's some research that shows that burying logs super deep (beneath the biologically active layer) is an effective method of long-term sequestration: https://pubmed.ncbi.nlm.nih.gov/35362755/

I'm with you! I'm a big proponent of DAC. I believe it'll be the key that unlocks a circular carbon economy. But, we're still a long ways from scaling it to a level where we can offset the carbon from burning fuel. We

by alexose 4y ago
That's a good point. Though, it might be possible to tack the sequestration step onto existing thinning and/or fuel reduction projects.

Here in Northern California there are huge swaths of firs that are dead or diseased as a result of drought. When they burn (which they will, at high intensity), they'll release their carbon back into the air. Seems to me that there&#
