The Japanese company Air Danshin Systems Inc. created a system that could be useful in case of an earthquake because it is a mechanism that literally floated a home. The technology was developed in 2005 by Youichi Sakamoto and according to the company, is relatively inexpensive and highly effective. Also it has a low maintenance cost over other mechanisms of anti-seismic protection.
Earthquake disaster kit – While tremor occurs, gas systems, water, sewerage and electricity are not affected because they operate through flexible pipes. The requirement for this mechanism to work is that it is a house built mostly of wood. All this is controlled by valves airflow that remain stable while floating. Upon completion of the telluric movement, returns to its original position.
In 2011, some 88 houses and small buildings throughout Japan already have through construction companies, although the price is not mentioned, is likely to come bundled with the value of the home. The company expects this system to be adopted in larger critical structures.
Seeing his performance seems that its effectiveness would be limited, especially if it is a house surrounded by others with higher and that lack of such a mechanism. This could affect structural walls and even the ceiling level, although it would be interesting to know whether in the Fukushima a house that service and had survived the earthquake last year.
