The EDV-01 is a disaster response unit developed by Daiwa Lease, first announced in January last year.
In an environment lacking basic infrastructure, two people can live comfortably for around one month with access to modern necessities such as water, electricity and communication equipment.
In the event of an emergency, the international standard size shipping container can be delivered via air, sea or land, and is usable immediately after installation. The outer wall of the container can be raised in approximately 260 seconds, creating a two-storey structure, with the kitchen, bath and toilet on the first floor, and the living space on the second.
“We’re involved in building temporary housing, to aid people in emergencies. It takes a month before construction can start. After a disaster occurs, people have to work in a place without facilities for a month. So we thought about making structures that could be transported in an emergency and would enable people to live on site for a month. That’s how we came to design this unit.”
“To supply energy, there’s a solar power system on the roof, and fuel cells underneath, which provide electricity using hydrogen. During the day, solar power is used, and at night, the fuel cells are used. A lithium battery is used to store the energy.”
Satellite technology is utilized for communication, and the dry composting toilet breaks down waste without using water. There is also an 800L water tank, with the water usable in the kitchen and shower, and drinking water is stored separately on the second floor.
“Regarding drinking water, if a tank is left for a month, the water can’t be used for drinking. So we’ve provided a machine that supplies water by using oxygen in the air.”
“We’d like to get feedback from local governments and the Self Defense Force while we continue developing this. At present, we don’t have any goal regarding sales.”
“With two floors, it uses a lot of power. It also takes up a lot of space. So we’d like to reduce the size from the current 20 feet to 12 feet. We think it might be more practical to have just the fuel inside, while the work is done outside. So, we’re thinking about a more compact size.”
