The paraSITE - an inflatable shelter for the homeless that runs off expelled HVAC air

In April of 1997, I proposed my concept and first prototype to a homeless man named Bill Stone, who regarded the project as a tactical response. At the time, the city of Cambridge had made a series of vents in Harvard Square "homeless-proof" by tilting the metal grates, making them virtually impossible to sleep on.

In his book, City of Quartz, Mike Davis describes a similar war on homelessness in Los Angeles. He lists a series of these hindrances throughout the city.

"One of the most common, but mind-numbing, of these deterrents is the Rapid Transit District's new barrelshaped bus bench that offers a minimal surface for uncomfortable sitting, while making sleeping utterly impossible. Such bumproof benches are being widely introduced on the periphery of Skid Row. Another invention, worthy of the Grand Guignol, is the aggressive deployment of outdoor sprinklers. Several years ago the city opened a 'Skid Row Park' along lower Fifth Street, on a corner of Hell.

To ensure that the park was not used for sleeping - that is to say, to guarantee that it was mainly utilized for drug dealing and prostitution - the city installed an elaborate overhead sprinkler system programmed to drench unsuspecting sleepers at random during the night. The system was immediately copied by some local businessmen in order to drive the homeless away from adjacent public sidewalks.

Meanwhile restaurants and markets have responded to the homeless by building ornate enclosures to protect their refuse. Although no one in Los Angeles has yet proposed adding cyanide to the garbage, as happened in Phoenix a few years back, one popular seafood restaurant has spent $12,000 to build the ultimate bag-lady-proof trash cage: made of three-quarter inch steel rod with alloy locks and vicious outturned spikes to safeguard priceless moldering fishheads and stale french fries."

PARASITES RESPOND TO THIS DEFENSE BY ANCHORING THEMSELVES WITH HOOKS AND SUCKERS ONTO SKIN, OR DIGESTIVE MUCOUS MEMBRANE, AND BY DEVELOPING PROTECTIVE DEVICES AND SUBSTANCES WHICH LESSEN DEFENSIVE CAPABILITIES OF THEIR HOST.

The system by which the device attaches or is anchored to the building is designed to allow the structure to be adaptable. The intake tube can be expanded or tightened to fit the aperture of the vent through an adjustable lip made possible by elastic draw-strings. Hooks are attached to the metal louvers for reinforcement.

THERE IS "TENSION" BETWEEN A HOST AND ITS PARASITE, SINCE THE HOST ENDEAVOURS TO GET RID OF THE FOREIGN BODY, WHILE THE PARASITE EMPLOYS NEW WAYS TO MAINTAIN THE CONNECTION WITH THE HOST.
