It's not super clear from the article how this achieves such a drastic reduction in energy use. It seems that maybe they are not accounting for energy used to dry out the desiccant at night; in that case the 60% figure might make sense during the cooling cycle only. The opening blurb also makes no sense to me; as it is AC units already suck moisture out of the air. Ask anyone who had a clog in an AC drain line :-)
