Honestly this seems like a super long-shot but at least semi-plausible avenue for putting DAC on the sort of learning curve that took lithium batteries from "high-end camcorder" to…

Another way of looking at this is that--while it doesn't have to be edible--you have to grow plant matter inside your house at a rate equivalent to what everyone in there consumes …

"Residential CO2 scrubber" seems like the sort of gadget eccentric rich people would buy, sort of a distributed DAC system.

The list of things that require an app rather than a web page was pretty long circa 2010, but it's quite a bit shorter now: it's mostly hardware access (Bluetooth/NFC), background …

If you're in the US, Costco has certain models at the old price through Saturday (or while supplies last). Just pulled the trigger on a 24GB/1TB 13" MbA for $250 off the new price.…

The most popular proposal (from Henry George) is to maintain individual land ownership, but impose a land-value tax that approaches 100% of the land rent. The result is that real e…

The difference is that investment in a company can create “more company”, whereas investment in land can’t create more land.

I'd like to see these if these can be scaled down into ebike size, or beyond that into micromobilty form factors that people carry around (like lightweight scooters and skateboards…

In the FAQ they discuss how in most of its range this particular species is invasive, feeds almost exclusively on humans, and is not believed to be a major food source for predator…

I grew up speaking German and still use "zu!" with my (otherwise English-trained) dogs for "get out of the way!".

This one is resistive (tiny and cheap to purchase) but will be just an emergency-backup shower once my home renovations are done. The house is getting a split-system air-to-water h…

I wish we did more e.g. district heating with that waste heat in the US.

The number I guesstimated for my e-scooter is about 500 miles per dollar of electricity.

The electric shower also seemed pretty optimistic. I live in an area with about 50°F/10°C ground temperature and my 14.4 kW water heater can just keep a relatively efficient shower…

Every single ICE car driving down the highway is throwing away enough waste heat to heat a small apartment building on a freezing cold day.

I feel like the gist here is that "faster, better, cheaper: pick two" doesn't apply to sub-optimally-spaced bus stops. You really can have all three, at the cost of some political …

I wonder if part of it is also that mining companies are generally allowed to just leave their tailings in a big pile near the mine rather than have to responsibly dispose of the m…

The diabolical case is M5 versus 10-32. About a 4% difference in diameter and about 0.8% difference in thread pitch. Basically indistinguishable with the naked eye and even the "ne…

They're obviously not the most affordable things around, but if you have an iPhone and spending ~US$250 on a pair of wireless earbuds won't unduly stress your budget, the transpare…

I think the way this would work is you would have your Canadian friend/owner drive it across and then return via another mode of transport. It's entirely possible you could get awa…

I had a couple of coworkers who had them. I vaguely remember it being based on a ~$35k value in 1997 dollars, so definitely out of my price range as a new graduate earning only a l…
