These rare clouds, sometimes called mother-of-pearl clouds, are 15 - 25km (9 -16 miles) high in the stratosphere and well above tropospheric clouds. They have iridescent colors but are higher and much rarer than ordinary iridescent clouds. Nacreous clouds shine brightly in high altitude sunlight up to two hours after ground level sunset or before dawn. Their unbelievably bright iridescent colors and slow movement relative to any lower clouds make them an unmistakable and unforgettable sight. 2. 3.

- Technology Ambri’s liquid metal battery technology is distinct from other storage options on the market today. Each cell consists of three self-separating liquid layers — two metals and a salt — that float on top of each other based on density differences and immiscibility. The system operates at elevated temperature maintained by self-heating during charging and discharging. The result is a low-cost and efficient storage system. Low Cost Ambri achieves low cost through the use of inexpensive, earth-abundant materials and a design that can take advantage of the economies of scale inherent to electro-metallurgy and conventional manufacturing. Flexible In the world of electricity storage, the liquid metal battery technology performs like both a tractor and a race car. Long Lifespan Liquid electrodes offer a robust alternative to solid electrodes, avoiding common failure mechanisms of conventional batteries, such as electrode particle cracking.
