Low-tech Inventions That Help Change Lives

angelaelle writes "The current issue of Popular Mechanics is featuring their Breakthrough Awards program for inventors. Some of the winning inventions help improve the living conditions for people in third world countries using low-tech materials and assembly methods. Technologies like this cookstove for people in Darfur, and in the case of this Windbelt developed by Shawn Frayne, could be used to provide cheap, clean energy alternatives. The website features fascinating, inspiring videos talking about the inventor's 'eureka moment', focusing on the inventor as well as the technology."

Appropriate Technology

[EaglemanBSA]

My master's degree is design of an appropriate technology vehicle -- turns out, the appropriate technology movement was abandoned, even to the point of making the phrase a faux-pas in the engineering community based on the idea that it provided mediocre solutions, and that the modern world was simply trying to placate the developing world with sub-par solutions. After projects like the OLPC however, I think it's become evident that applications of simple technology to problems that demand it deserve just as much attention. Giving someone who can't afford gasoline or buy spare car parts a car is like giving Robinson Caruso a cell phone where he can't get reception.

Use them NOW

[Ralph Spoilsport]

Use these energy saving systems NOW in countries like the USA and Europe. Conserve energy NOW, especially oil and natgas. Oil can be made into all kinds of amazing substances and burning it up as fuel is like making logs out of $20 bills. Natgas is great for making into fertiliser. We need oil for materials and natgas for food. We need to use Other Technologies for electrical generation (Solar, Wind, hydro, nuke, geothermal, whatever) so we can stretch out our supply of petrochemicals as long as possible.

People can do their part by using these personal conservation technologies in their own lives.

A few times a week, I set out a big pot of stew or chili or soup in my solar cooker. Even in the dead of winter, I come home to a hot meal at the end of the day. It Works. And it's awesome.
