According to the BBC, scientists at the University of Pennsylvania claim that coating them will reduce water use during flushing by 90%. It is also reported that the coating does not allow bacteria to accumulate and prevents the formation of unpleasant odors.
A substance that is much more slippery than Teflon will be destroyed by urine, so it will need to be applied again after 50 rinses of water.
“Our team has developed a reliable, biological, liquid and antibacterial coating that can actually make the toilet self-cleaning,” says Professor Tak Sin Wong.
Researchers hope the discovery will save water. Every day, more than 141 billion liters of water are used for disposal in toilets.
