Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. Sometimes, past technologies can be copied without any changes. More often, interesting possibilities arise when older technology is combined with new knowledge and new materials, or when past concepts and traditional knowledge are applied to modern technology. Inspiration is also to be found in the so-called "developing" world, where resource constraints often lead to inventive, low-tech solutions. Contains 159 images in black & white.

Sex is cheap. Coupled sexual activity has become more widely available than ever. Cheap sex has been made possible by two technologies that have little to do with each other - the Pill and high-quality pornography - and its distribution made more efficient by a third technological innovation, online dating. Together, they drive down the cost of real sex, and in turn slow the development of love, make fidelity more challenging, sexual malleability more common, and have even taken a toll on men's marriageability. Cheap Sex takes readers on an extended tour inside the American mating market, and highlights key patterns that characterize young adults' experience today, including the timing of first sex in relationships, overlapping partners, frustrating returns on their relational investments, and a failure to link future goals like marriage with how they navigate their current relationships. Drawing upon several large nationally-representative surveys, in-person interviews with 100 men and women, and the assertions of scholars ranging from evolutionary psychologists to gender theorists, what emerges is a story about social change, technological breakthroughs, and unintended consequences. Men and women have not fundamentally changed, but their unions have. No longer playing a supporting role in relationships, sex has emerged as a central priority in relationship development and continuation. But unravel the layers, and it is obvious that the emergence of "industrial sex" is far more a reflection of men's interests than women's.
