Testing solid materials in the cell to minimize iodine loss by evaporation. I expect halloysite clay ( nanotubular) to perform well. Lugol's solution, used in medicine for centuries, is 10% KI/ 5% I2 in water. Grafoil and zinc electrodes.
The zinc is a section of zinc flower pots ( Amazon) with the wax removed by use of ethyl acetate. Cheap and flexible source of Zn for electrode use.

I am developing "zinc iodine" secondary cells (1.4 V open) with 0.7V cutoff using Lugol solution ( iodine and KI in aq. solution)/ zinc anode and carbon cathode (current collector). Halloysite is nanotubular clay.

Here is what Bard ( AI/Google) says about this question:
Were parachutes used with the German V-2 rockets for recovery studies?
Yes, parachutes were used with the German V-2 rockets for recovery studies. The V-2 was a ballistic missile, and as such, it was not designed to be recovered. However, the German rocket engineers wanted to learn more about how the V-2 performed in flight, and they also wanted to develop a recovery system in case the V-2 could be used for future scientific or commercial missions.
The Germans developed a two-parachute recovery system for the V-2. The first parachute, called the drogue parachute, was deployed at an altitude of about 10 kilometers (6.2 miles). The drogue parachute slowed the V-2 down and stabilized it. Once the V-2 had slowed down enough, the main parachute was deployed. The main parachute brought the V-2 to a gentle landing.
The Germans successfully recovered several V-2 rockets using this parachute system. The recovered rockets were then inspected and analyzed by the engineers. This data helped the Germans to improve the design of the V-2 and other rockets.
After World War II, the Allies captured many of the German rocket engineers and hardware. The United States and the Soviet Union both continued to develop the V-2 rocket, and they also used parachute recovery systems to recover their rockets.
Today, parachute recovery systems are commonly used on sounding rockets and other small rockets. This allows the rockets to be reused and the data from their flights to be recovered.
