Carbon freezes at the temperature of around minus 80 degrees Celsius and the only place in this environment where this can happen naturally is 15 kilometers above our head. In simple words, this natural phenomenon doesn't takes place on the surface of the earth but in that layer of atmosphere which is called as stratosphere.
The scientists and researchers at High Hopes Labs has come up with a unique method of capturing carbon in its solid form by sending balloons high in the air along with a device (small version of airborne compressor) which extracts carbon from the atmosphere.
The solid carbon is then filled into the pressure vessels and brought back on the ground. The solid carbon then turns into gas once again after it get heated and these pressure vessels can either be stored or sold to those who need CO2 for industrial or chemical processes.
The firm has tested this method at a small scale and after achieving substantial success now it aims to carry it out at a bigger scale. High Hopes Labs will now design big balloons within two years which will enable the firm in removing a metric tonne of carbon-di-oxide per balloon, per day from the atmosphere.
