VISION

ARTWORK

FONTUS IS A SELF-

FILLING WATER BOTTLE FOR YOUR

BICYCLE. THIS DEVICE COLLECTS THE

MOISTURE CONTAINED IN THE AIR, CONDENSES IT AND STORES IT AS SAFE

DRINKING WATER. POWERED BY

SOLAR CELLS, IT CAN HARVEST UP TO

0,5 L WATER IN AN HOUR´S TIME UNDER

THE RIGHT CLIMATIC CONDITIONS.

MORE THAN 2 BILLION PEOPLE IN MORE THAN 40 COUNTRIES LIVE IN REGIONS WITH WATER SCARCITY

(FAO, 2012)

“WATER SCARCITY MAY BE THE MOST UNDERESTIMATED RESOURCE ISSUE FACING THE

WORLD TODAY. EVERY MEASURE TO MITIGATE THIS UPCOMING CRISIS IS A WELCOME ONE.”

(EARTH POLICY INSTITUTE, 2002)

INSPIRATION AND RESEARCH

71 % of the earth´s surface is covered with water

2,6 %of it, is freshwater

68,7 % is ice and permanent snow

30,1 % is groundwater

0,3 % is in lakes and rivers

0,037 % is in the atmosphere

13,000 km3

THE CHALLENGE

IN 2030, 47% OF THE WORLD´S POPULATION WILL BE LIVING IN AREAS OF HIGH WATER STRESS

(WWDR, 2012)

PROJECT GOALTO CREATE A SMALL, COMPACT AND SELF-SUFFICIENT DEVICE ABLE TO ABSORB HUMID AIR,

SEPARATE WATER MOLECULES FROM AIR MOLECULES AND

STORE WATER IN LIQUID FORM IN A BOTTLE.

FONTUS CAN BE APPLIED IN TWO DIFFERENT AREAS. FIRSTLY, IT MAY BE INTERPRETED AS A SPORTY BICYCLE

ACCESSORY. USEFUL ON LONG BIKE TOURS, THE CONSTANT SEARCH FOR FRESHWATER SOURCES SUCH AS

RIVERS AND GAS STATIONS CAN CEASE TO BE AN ISSUE SINCE THE BOTTLE AUTOMATICALLY FILLS ITSELF UP.

SECONDLY, IT MIGHT BE A CLEVER WAY OF ACQUIRING FRESHWATER IN REGIONS OF THE WORLD WHERE

GROUNDWATER IS SCARCE BUT AIR HUMIDITY IS HIGH. EXPERIMENTS SUGGEST THAT THE BOTTLE COULD HARVEST

AROUND 0,5L WATER IN ONE HOUR´S TIME IN REGIONS WITH HIGH TEMPERATURE AND HUMIDITY VALUES.

COLD SIDE

H O W I T W O R K S In order to achieve condensation, one must cool hot, humid air down. The device has a small cooler installed in its centre called Peltier Element.

This cooler is divided in two: When powered by electricity, the upper side cools down and the bottom side gets hot. The more you cool the hot side down, the colder the upper side will get. Consequently, these two sides are separated and isolated from each other.

The air enters the bottom chamber at a high speed when moving forward with the bike and cools the hot side down. Moreover, when the air enters the upper chamber it is stopped by little walls perforated non-linearly, reducing its speed in order to give the air the needed time to lose its water molecules.

The condensing structure represents the largest surface in the smallest space possible.This provides a large surface for condensation to happen. Droplets then flow through a pipe into a bottle. The bottle can then be turned to a vertical position and losened. Every kind of PET 0,5l bottle fits.

BOUND IS AN INFLATABLE LIFE VEST FOR

PARENT AND CHILD. IN CASE OF A

CATASTROPHE, INFANT AND PARENT WILL STAY

SAFE AND CLOSE TOGETHER

THE CHALLENGE

AFTER THOROUGH RESEARCH INTO SAFETY REGULATIONS OF AIRPLANES AND SHIPS AND LIFE VESTS IN GENERAL, I CAME TO REALIZE THAT THERE IS VERY LITTLE EFFORT INVESTED IN GUARANTEEING THE CONNECTION OF AN INFANT TO HIS PARENT IN CASE OF A CATASTROPHE. INFANTS MUST USUALLY WEAR AN INDIVIDUAL LIFE VEST. IN CASE OF AN ACCIDENT, PARENTS MUST CARRY OR GUIDE THEIR CHILD WITH THEIR OWN HANDS, BEING OBSTRUCTED IN PERFORMING OTHER MOVEMENTS SUCH AS OPENING DOORS OR SWIMMING. FURTHERMORE, THERE IS A GREATER CHANCE FOR INFANTS TO GET SEPARATED AND LOST IN THE CHAOS OF THE SITUATION. THIS PROJECT WAS INSPIRED BY THE PROFOUND BOUND BETWEEN A CHILD AND ITS MOTHER.

THE LIFE VEST

BOUND MAKES IT POSSIBLE FOR PARENTS TO KEEP THEIR CHILDREN NEAR TO THEM IN CASE OF AN ACCIDENT.

BOUND ALLOWS A PARENT TO CARRY THEIR CHILD WHILE HAVING AT THE SAME TIME BOTH HANDS FREE

TO GET IN SAFETY. ALTHOUGH CONNECTED, THE LIFE VESTS OF PARENT AND INFANT ARE INDIVIDUAL PARTS

AND CAN BE SEPARATED FROM EACH OTHER EASILY. THEY HAVE INDIVIDUAL AIR CHAMBERS WHICH

MUST BE INDIVIDUALLY INFLATED AND THE DISTANCE BETWEEN THEM CAN ALSO BE EASILY REGULATED.

THE CHALLENGE

ACCORDING TO THE UNHCR, 45,2 MILLION

PEOPLE WERE FORCEFULLY DISPLACED AT THE END OF 2012,

THE LARGEST NUMBER SINCE 1994.

80% OF THE REFUGEES WORLDWIDE ARE WOMEN

AND CHILDREN.

IN MOST ARMED CONFLICTS, WOMEN AND CHILDREN ARE INNOCENT VICTIMS. THEY ARE EITHER

FORCED TO LIVE UNDER TERRIBLE CONDITIONS OR TO LEAVE

THEIR HOMES IN SEARCH OF SECURITY. EXPOSED TO FIREFIGHT

AND BOMBING, THEIR LIVES ARE CONSTANTLY AT RISK. THIS PROJECT IS INTENDED TO INVITE US TO REFLECT

ON CIVILIANS´ SITUATION IN ARMED CONFLICTS TODAY.

MAJOR WARS AND CIVIL UNREST, 1,000+ DEATHS PER YEAR

MINOR SKIRMISHES AND CONFLICTS, FEWER THAN 1000 DEATHS PER YEAR

THE BULLETPROOF

VEST

© K R I S T O F R E T E Z Á R

FINAL PROTOTYPE

THE VEST HAS A BULLETPROOF MATERIAL ON THE OUTSIDE AND IT IS CUSHIONED ON THE

INSIDE. THE FRONT SIDE IS CURVED SO THAT THERE IS ENOUGH SPACE FOR A BABY TO SIT

BETWEEN MOTHER AND VEST. AN INCLINED SURFACE ABOVE THE BABY’S HEAD PROTECTS

AGAINST SHRAPNEL AND OTHER PROJECTILES COMING IN FROM A HIGHER ANGLE.

STRONGOLD MAKES IT POSSIBLE FOR WOMEN TO TRANSPORT THEIR BABIES EFFICIENTLY BEING ABLE TO CARRY OTHER BELONGINGS TOO WHILE BEING BOTH PROTECTED.

THIS PRODUCT COULD BE DISTRIBUTED BY ORGANISATIONS LIKE THE UNHCR FOR WOMEN ESCAPING

TO REFUGEE CAMPS WHERE, ONCE IN SAFETY, THEY WOULD HAND IT OVER TO OTHERS IN NEED.
