Green Horizons‘ Central Service Unit 40 mobile infrastructure trailer is the emergency housing version of the Swiss Army knife. Developed for rapid emergency response after a calamity, the trailer provides much of the support needed to create a temporary, off-the-grid village. Fresh water, power, and communications are all packed into the CSU and can be quickly connected to a number of buildings.
The core design strategy of the Central Service Unit is to provide multiple layers of services and redundant power options so that users can quickly set up and maintain basic infrastructure almost anywhere at any time. The large trailer is filled with integrated technologies all supported by a central controller. When pulled up to a site the unit self-levels in a matter of minutes and can be operated by a small team.
A telecommunications system can operate using microwave antennas in local signals or satellite telecommunications, which provides wi-fi, security monitoring and telephone access. Local water sources can be utilized for potable water using an onboard reverse osmosis filer which can handle briny and salt water providing a astonishing 19,000 gallons a day.
The power system is integrated from three chief energy sources and supplied through a central stack of inverters. A 5kW solar array made from 18 240 watt modules is deployed from the side of the trailer feeding a large battery bank. Another 5kW of clean energy is supplied by a Hydrogen fuel cell which quietly runs in the back of the trailer, emitting only water vapor. A back up diesel generator provides 12 kW of DC juice that is converted by the power inverters. The system can run on each of the three power supplies independently or in any combination to provide an impressive 74,000 watts of energy.
The power output is enough to independently support 20 of their QuickHab homes. Power and water hook ups are feed directly from the CSU to the homes using quick couplings. The design is a bit rudimentary with what looks to be a lot of extra space, but considering the extreme weather events over the summer—and likelihood that there are many more to come—the CSU couldn’t come too soon.
