The Army has cleared the way for
ocean-based clean energy and water. The U.S. Army Corps of Engineers has given
a Section 10 Permit to Renew Blue Inc. subsidiary Independent Natural Resources
Inc. (INRI) to install a commercial wave-powered demonstration facility. The
energy-producing facility is designed to turn waves into electricity while also
producing fresh, desalinated water.
This is the first instance of a
Section 10 Permit issued to demonstrate a commercial wave-energy facility.
"This permit marks a significant step to help Texas achieve its goals for new
sources of energy and clean water," says Douglas Sandberg, vice president of
facilities require substantial amounts of electricity. INRI's Seadog Pump is
powered solely by electricity developed by wave energy. Since 40 to 50 percent
of operating costs in the desalination process are attributed to energy, the
self-energy-generating Seadog offers a low-cost solution for producing fresh
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
