Has anyone made Gilbert's version of an e-cig to see it it actually worked? I bet it did. It is really quite a good design. Much better than a lot of the crap we have on the market today that is for sure. So we cannot discount his creation and just blow it off. BTW even the Wright Brothers used Leonardo's design concepts for their heavier than air craft. They took his design and innovated it to make it work. Leonardo's design inspired many others. It is quite possible Lik was inspired by Gilbert. We may never know.
