AI in the Data Center

Figure 1. Powering Artificial Intelligence

In a recent New York Times article, Mark Hung, a VP at Gartner, said that “almost everything Google is announcing these days is AI-related.” He said, “Google has a lead on artificial intelligence over many of its competitors, and it’s going to use that as a weapon to advance their products.” Although

Understanding the Basics of DC-DC Conversion

Figure 1: DC-DC converters can be isolated or non-isolated

When Allesandro Volta made a battery out of copper and zinc disks and brine-soaked cardboard, it was a novelty and the low power DC produced had few practical applications. As electricity became better understood and it was discovered that rotating magnets could induce AC current in wires, the world of power

Growing Developments in LED Horticultural Lighting

Figure 1: Average plant response to PAR

The horticultural lighting industry is in the middle of a disruptive change – growers are now getting to grips with the LED ‘solid-state’ artificial light alternative, traditionally provided by high-pressure sodium lamps (HPS). HPS lamps are relatively efficient at 100-150 lumens per watt, actually similar

How to Make it Easier to Turn Plant Waste into Biofuels

Next-generation ammonia-salt based pretreatment processes facilitate efficient breakdown of waste biomass such as corn stalks, leaves and other residue (called corn stover).

Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels. Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well

Improving Solar Cells' Back-Contact with DOE Project

Researchers will work to improve the solar cell's back contact, the layer furthest from the light source.

Fifty years ago, solar power was rare, expensive and specialized - barely a blip on the energy landscape. Today, rooftop and commercial solar markets are exploding, generating 2.5% of all electricity in the U.S. and fueled by the urgency of climate change. For many years, Colorado State University

Reversing Electrons' Course Through Nature's Solar Cells
Think of a train coming down the tracks to a switch point where it could go either to the right or the left -- and it always goes to the right. Photosynthetic organisms have a similar switch point. After sunlight is absorbed, energy transfers rapidly to a protein called the reaction center. From this
