Ubiquitous Energy Ubiquitous Energy Ubiquitous Energy, Inc. is an American solar energy company headquartered in Redwood City, California that designs transparent solar technology to absorb ultraviolet and near infrared light (NIR) (wavelength span of λ= 650– 850 nm) while transmitting visible light through its medium called ClearView Power. Ubiquitous Energy is a privately funded company founded in 2011 by Miles Barr, Vladimir Bulović, and Richard Lunt. Current solar power is created in solar plants that take up lots of surface area far away from where the energy is consumed. It is estimated 15% of the energy is lost during distribution.

Umkehr effect Umkehr effect The Umkehr is the time variation of the ratio of the scattered intensity at two different wavelengths. The word means 'reversal' in German. The Umkehr effect is observed when measurements are made with ultraviolet spectrophotometer of the ratio of the zenith sky light intensities of two wavelengths in the solar ultraviolet when the sun is near the horizon. The shorter of two wavelengths (intensity "I") is strongly absorbed and other (intensity "I' ") is weakly absorbed. If the value of log("I"/"I' ") is plotted against the sun's zenith angle, it is observed that this log-intensity ratio decreases as
