MOTH EYES FINDINGS HELP CREATE A SUPERIOR SOLAR ENERGY COLLECTION FILM

Moth eye-inspired material now boosts efficiency of solar cells By Ben Coxworth 21:03 January 23, 2011 In order for a solar cell to be as efficient as possible, the last thing it should be is reflective – after all, light should be getting absorbed by it, not being bounced off. With that in mind, a few […]

VIBRATION AND ENERGY GENERATION

Vibration &Energy Harvesting: Powering Up the Battery-Free World Oct 31, 2010 23:58 ideyoshi Kume The amount of electricity generated by vibration is proportional to the frequency and amplitude of the vibrator, which means that maximizing both will easily increase output. Because of the way vibration-based generators work, however, fine adjustment is needed to ensure they […]

JAPAN & OTHER COUNTRIES IN ENERGY EFFICIENCIES

Energy Harvesting: Powering Up the Battery-Free World Oct 31, 2010 23:58 ideyoshi Kume One of the reasons that overseas manufacturers have pulled so far ahead of Japan in practical application is that domestic manufacturers are overly concerned with generating electricity. Many firms in Japan have been developing power generating devices for years, but the thrust […]
