Truly sustainable computing

Plenty could be written about this subject. I just want to call for change in two areas, because I believe they'd have the greatest impact here and now: Desktop computers should have a projected life span of 20 years. Laptops and mobile phones should have a projected life span of 10 years. Why 10 years [...]

Modern lawn care: a lot of hot air

One of the things I strongly believe in is the need for manual labor, especially during these highly industrialized times.

A few tidbits: Better propeller designs decrease propeller noise by up to 90% Insulating the engine [...]

She buys the raw materials from trash pickers, whom she pays at above-market rates, and, using trained artisans, creates beautiful products from trash that would be clogging landfills, streets and [...]

Some say global warming is caused by man, mainly by CO2 emissions, while others say it is part of a larger picture of cyclical global warming and cooling events that have occurred throughout history. Unfortunately, the debate is mostly [...]

Signs of overpopulation

Signs of overpopulation are virtually everywhere -- and can even be seen when it comes to the basics of life, like food and shelter. Besides the obvious signs, like crowded cities and roads, and rampant consumption of our natural resources, there are other signs that may or may not be readily apparent, depending on your [...]
