Cool the earth with balloons

The project of spraying water into the stratosphere (Spice) advocates spraying small droplets of water into the atmosphere from a balloon that is 'chained' to the ground.

But the pioneering project in the UK to save the earth's climate has been delayed for at least a year now. The device will also be used to spray extremely small droplets to cool the earth, like volcanic activity.

The project leaders said Spice was hampered by legal causes, intellectual property and community participation.

The patent application was compiled by Cambridge University scientists Hugh Hunt and Chris Burgoyne and businessmen living on Man Island (British) Peter Davidson, who is primarily responsible for the project's technology.

According to members of Spice, such a non-profit community project does not need to register for copyright, as it will not bring any profit.

The Physical and Engineering Research Council (EPSRC), which funded the project, delayed another 6 months to allow interested parties to participate.

Another reason the project was postponed was that although it was discussed at many international forums, including the UN Conference on Biodiversity, there is no comprehensive mechanism for managing the category. this project.

The ball was supposed to be aired in October last year from Sculthorpe Airport in Norfolk (England). The ball is expected to be kept at a height of 1km. Water is pumped onto the ball through the pipe from the ground. Scientists are responsible for managing the amount of water sprayed, and how the ball and the connecting cord will change before the impact of the wind.

The team intends to use the information obtained to develop a much larger set of devices that can be lifted higher to spray sulfate particles that reflect sunlight back into space, thereby cooling the earth.

Reducing solar energy to the ground is one of two methods of regulating the earth's climate, which is of great interest nowadays. The other method is to use a giant sun shield to reflect the sun.

Measures such as painting the white roof, planting trees with good reflective leaves are also a way to make the earth cooler.

Opponents, including many environmental groups, argue that these technologies can cause unwanted consequences, and aim to avoid the task of reducing greenhouse gas emissions.

In addition, these measures do not address the gradual ocean acidification because the oceans absorb carbon dioxide from the atmosphere.

But supporters argue that those technologies are needed in the context of climate change going on at an accelerated pace, so an emergency response is needed.
