New miracle material poised to alleviate the global water and energy crisis Image Credit / Wikimedia Commons By: Carolanne Wright, Natural News. Daunting observations made in the Population Institute report, “2030: The ‘Perfect Storm’ Scenario,” clearly illustrate the dire need for innovative solutions concerning the pending worldwide energy and water crisis. Yet, scientists at Nanyang Technological University (NTU) in Singapore have steadily worked over the last five years to create a seemingly miraculous material that produces hydrogen, creates clean water and can even generate energy – all at a very low cost in contrast to the current technology available. Called Multi-use Titanium Dioxide, the material is formed by creating nano fibers from titanium dioxide crystals, which are then used to construct a flexible membrane. As noted in Science Daily, the nanomaterial created from titanium dioxide can: Sources: Credits:
