As a result of the previous promising experiments with the superabsorber, we decided to go for the next step.
A first sample was built using this material and was brought to water - for the first time in a lake. The test sample is only the shell, it is not yet operational and it is not filled with "storage water", The experiment confirmed that the material is easily wetted and also emptied again when taking the storage out of the waterr. However, as the image shows, the density of the wet material is still lower than pure water, meaning that the storage is swimming at the surface in horizontal position.
Next step therefore. Make sure that the some weight is added to the insulation.
