Yields of most plants are higher in the tropics: there is more sunlight, more water, and no frost. Wheat, historically, hasn't been able to benefit from this as it wasn't adapted to the climate. Most minor minerals are present in

One problem is the binary of "sober". Opioid substitution therapy has a long track record of effectiveness, but when treating homeless addicts we all too often insist they go through withdrawal, to nobody's benefit. Not all h

A fair correction. I was only aware of the essay; I tend to avoid watching videos whenever possible. Notably, most of the other ideas in that video are also improbable: drone-delivery is not as easy as it sounds; multilateralism is hard; or

Von Neumann may have meant the cumulative delta-T as of 1955; he may have also been referring to the expected equilibrium delta-T given the total emissions as of 1955. I don't think he meant the change over a generation; he was saying

You can cap the effective margin with even a very generous limit — say, processing fees no more than 3x the cost of servicing chargebacks — and mostly eliminate the concern about "quietly banning" businesses via processing fees. B

For most cases this could probably be fixed by using a more abstract color scheme: rather than "red", "blue", "grey", and such, maybe "warn_0", "emphasis_0", "dull_0", etc.

A lot of the "water used for livestock" is used on crops that are exported for livestock that live elsewhere. A tax on meat domestically won't hit that. A tax on exports would be very unpopular, for obvious reasons.

IIRC, a lot of the energy use in a plane flight is due to the initial acceleration. So double the capacity is more than double the distance. You can also just use a bigger battery when the weight efficiency is better. Amprius is planning to
