Hello, this is Luca De Ruggiero from design team 23, I really like the project you’re developing and I like the design ideas; I’ve seen the drownings and the logic behind the operation of the battery and I was wondering if there was a very long lasting battery that can avoid a frequent substitution.
I’ve found an article that speaks about various kinds of batteries and explains the benefits of each one, maybe you can find it useful; by the way my compliments again for your work and your ideas.
