The 20K Home project began in 2005 as an ongoing Rural Studio research project to address the need for affordable housing in Hale County, provide an alternative to the mobile home, and accommodate potential homeowners who are unable to qualify for commercial credit. The 20K Home project gets its name from the highest realistic mortgage a person receiving median Social Security checks can maintain. The objective of the Rural Studio students is to design and build a model home that could be reproduced on a large scale by a contractor and built for $20,000. Rural Studio has designed seventeen versions of the 20K Home with costs of approximately $12,000 for materials and $8,000 for contracted labor and profit.
In a series of videos posted to YouTube, engineer Aliaksei Zholner demonstrates a miniscule V8 engine he designed that is built completely from paper (with minor bits of scotch tape to prevent friction). The engine is so tiny it fits inside the plastic container found inside a Kinder egg. In the the videos Zholner demonstrates the progress of the engine coming together over several months, and the latest clip posted this weekend incorporates a paper throttle that effectively controls the speed of the little whirring device using compressed air. You can also see his wildly popular model v6 engine from last year.
