Gas harvesting apparatus
An apparatus that will allow collection and temporary storage of gaseous fuels harvested from shallow waters.
Visually explained in the video below:
The bucket works as an underwater bell. After bleeding the air from it, it can be filled up with gas which can then be transferred to the condom without any pressure pump. In return, the condom can be used to find out if the gas contains energy and if so, as a makeshift container for later.
