The Japanese company Daiwa Lease has developed a transportable outpost for housing rescue workers during a relief operation following a disaster. Totally autonomous, it is designed to ensure the survival of two adults for a month.
The unit, called EDV-01 (“Emergency Disaster Vehicle”), comes in the form of a “twenty-foot container”, with dimensions defined by the ISO international standard is 20 feet (6.058 m) for length , 8 feet (2.438 m) in width and 8.5 feet (2,591 m) in height. Hydraulic pumps used to bring in 260 seconds its outside and thus to form a floor with beds and a desk equipped with a satellite communication system. The first level contains the equipment providing the minimum comfort for the occupants: a shower (with a tank of 800 l), biological toilet, a kitchen, a device that produces potable water by condensing water vapor present in air (production capacity of 20 liters per day), a fuel cell and battery. This configuration allows the unit to move easily through various means of transport (boat, truck, helicopter, etc.).
Power is provided by fuel cells and solar panels connected to a battery. The battery, a power output of 600 W was provided by the American company ReliOn. It is fed by a reservoir containing a sufficient amount of hydrogen gas for a month. Solar panels are of two kinds. The first, of 1680 Wp, are modules of type HIT (Heterojunction With Intrinsic Thin layer). Supplied by Sanyo, they are placed on the roof. The walls of the first level are equipped with 390 W of spherical silicon modules Green Venture 21. Li-ion battery with a capacity of 10 kWh was provided by Eliiy Power, a company created to further work on Eliica, the electric car developed by Professor Shimizu of Keio University. An LED lighting can reduce electricity consumption.
The company has yet built a single prototype. They plan to present it to relief agencies (fire, police, etc.) In order to improve it and develop a commercial version.
