Dengyo Unveils "Rectenna" Device That Harvests WiFi and DVB Signals
Radio signals are mostly used for information transfer purposes, but the energy they contain is mostly left unused, bouncing off the various obstacles until all of it is transformed into lost heat. Nihon Dengyo Kosaku, a Japanese company, has come up with a device that harvests radio signals and uses their power.
New Phase Change Material Offers Huge Energy Savings in Buildings
The novel non-deformed energy storage phase change material (PCM), as the scientists dubbed it, can efficaciously regulate heat, by virtue of its large energy storage capacity. The best part is that it could be cheaply manufactured.
Aquacube Water Treatment System Provides Clean Water in Underdeveloped Countries
Water, a key element of life, has always been one of the most exploited natural resources. Even if we have a lot of water (71 percent of the earth’s surface), in some places on earth drinking water still remains an unsolved issue.
