Air exchange is the most economical solution. You can’t stuff enough plants in a typical home to make a measurable difference and there are other pollutants such as VOCs that air exchange will address. Here are the two least expensive opt

I agree. Many people essentially live in sealed boxes that only receive ventilation through cracks and the occasionally opened door or window. My home averages around 800 ppm and that is with a fresh air ventilation system that is constan

All successful species have strongly developed instincts to maximize the probability of passing their DNA to children who can in turn do the same. For humans, birth timing and number of children are some of the most critical parameters in

I believe it would have the opposite effect. Lower death rate appears to lead to people having fewer children. Most countries with GDP over $20K per person now average fewer than 2 children per woman[1]. I think a widely-available longev

Armored vehicles have thin armor on top, which allows effective top-attack by smaller munitions such as SADARM.[1] SADARM is smaller than a typical toaster and weighs 12 kg. An even smaller micro-drone could just attack a tank's gun by

I strongly disagree. 1) Increasing the number of investors, increases a CEO’s effort required to maintain the same quality of investor relationships. 2) An investor doesn’t need to be malicious to be a major problem. Misunderstandings, mis

In spite of its mistakes, the CDC has still been one of our best sources of guidance throughout the pandemic. Many of our politicians, media personalities, and social media platforms have failed miserably in comparison. I’m all in favor of

Fun and interesting work of foresight from 26 years ago! I assume the DigiCash promotion was part of the inspiration... or maybe it was vice versa? Either way, an interesting connection to the article's authors as well.
