  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Goodbye Light Bulb Jokes?

    Once upon a time, joking about ‘how many it takes to screw in a light bulb’ was a great way to poke fun at people’s intelligence. After all, what could be easier than screwing in a light bulb? Any idiot could do it. Not so any more. Lighting has exploded into a sophisticated business. And for those who manage commercial buildings it can be downright intimidating. Figuring out ...

  • The Comprehensive Potential of LEDs in U.S. Commercial/Industrial Operations

    One of the biggest expenses associated with industrial and commercial operations is energy usage. Almost every type of commercial industry requires energy to function, from simple warehousing and distribution of goods to full on manufacturing and processing plants, and as the cost of energy increases, so too do operating expenses. When we think of the electrical energy consumed by such ...
