An estimated 4,000 children die each day from water related diseases, the primary cause being contaminated drinking water. Almost a billion people collect water from open water bodies. These sources are extremely prone to both microbiological and chemical pollution, like cholera, pesticide and industrial pollutants.
Our innovation is a scalable, low tech, activated charcoal producing unit that runs on solar energy. The unit delivers high grade activated charcoal which can be readily incorporated into a slow sand or similar filter to greatly enhance water purification standards.
Our idea stands apart from other clean drinking water solutions because we use existing natural water sources as opposed to drilling for water underground and further tapping strained groundwater resources. Most water filtration solutions rely on single use filters which must be replaced frequently to ensure proper function. Replacing filters is not only environmentally wasteful and financially burdensome but rural communities often do not have ready access to replacements due to their location. The result is communities being forced to drink harmful water.
We address this problem by placing the power to create filters in the hands of the people who use them. Our device is capable of producing a kilogram of activated carbon daily, enough to filter up to 20,000 litres of water. Communities and individuals can be economically empowered through activated carbon and filter production. Conventionally activated carbon is produced in large unsustainable fossil fuel powered industrial furnaces. We use solar power thereby providing a sustainable alternative to polluting methods.
Parametrically designed and Digitally Fabricated, this thermo-electric generator attaches onto the
exhaust pipe of a motorbike and exploits the temperature difference between the hot exhaust pipe and the heat sink that is air-cooled. It recovers the waste heat and converts it to electricity that is stored in a battery, that can later be used to charge your cell phone.
The Brief: Leverage the power of IoT to help solve California’s ongoing drought.
A Solution: Our solution aims to identify stretches along the aqueduct system that are most vulnerable to evaporation. This will be done by measuring real-time data of the various parameters that cause evaporation, via small devices floating on the canal itself.
After collecting and mapping this information, cost effective solutions like solar panel bridges or wind barriers can be strategically placed to bandage the most vulnerable parts of the aqueduct during
different times of the year.
As the drought in California continues into its 4th year drastic efforts have to be made to solve the crisis. It is estimated there is a loss of 9300 acre-feet of water per day simply through evaporation in the California State Water Project’s aqueducts.
In essence, Eva is a small solar-powered floating hydrology and meteorology lab. She is equipped to measure water temperature, dry bulb and wet bulb air temperature, pressure, relative humidity, irradiance, wind speed, wind direction and the certain chemical attributes of the water. These factors are used to calculate precise, instantaneous and localized values of evaporation.
Though Eva’s conception was inspired by the drought in California, her applications are global.
