Although 100% Muslims talk about prayers, less than 5% of them pray five times a day. Still, if water conservation is the idea, let them do tayamum or dry ablution.
Hi-tech Wudhu sounded funny to me in the backdrop of "Muslim toilets" that some Muslims proudly show to the visitors during the house parade of their new pricey houses.
Are these machines a proof of their "Muslimness"?
At least we can invent something.
