COOLBA (Team CB-OND)
COOLBA’s main purpose is to reduce the E-waste of households’ appliances. It’s based on the 2PACL, a CERN technology, and combines 3 household utilities: Fridge, Heating and Air-Con.
COOLBA is a centralized system capable of refrigeration and heating, using a shared CO2 circuit and compressor, therefore reducing the number of singular systems per home.
GeoLight (Team Ipiranga)
On a daily basis, Geolight Works as a street light that is capable of capturing the CO2 from the air.
Once the flame detector is activated, Geolight launches the CO2 (that has been previously pressurized and turned into liquid) to contain the fire and avoid its spreading until the fire-fighters arrive.
