The Fresh Clouds project is built upon the concept of harvesting the byproducts of human consumption, through an innovative use of today’s technology and materials, into a resource stream. The scalable system not only converts methane, but also cleans and converts the byproduct hot exhaust directly into energy at a local level, therefore reducing the required amount of infrastructure to ecologically convert methane to energy. Rather than building or maintaining a large network of gas infrastructure to a single distant electrical plant, Fresh Clouds propose installing micro-turbines at each passive well head, to continuously convert methane into electricity that is fed directly into the NY metropolitan grid.
The Clouds are composed of high-strength ETFE on the exterior and ETFE coated with CO2 absorbing titanium dioxide and PTFE on the interior. The high, internal temperatures of the Fresh Clouds, in comparison with ambient air temperature, result in a tremendous amount of lift. The base of each Cloud is tethered to three steel cables which run through flywheels that are arrayed around the micro-turbines, under an earthen enclosure. These tethering cables are pulled by the Cloud’s lift, causing the flywheels to generate a large amount of electricity. As the cloud approaches a FCC allowable maximum height of 500 ft, the cables pull taught and a series of vents open at the top of the cloud to release the cleaned hot exhaust. The internal temperature of the cloud returns to equilibrium and the cloud descends to the ground to repeat the process.
