New Heat Cell Could Enable Grid-Scale Thermal Batteries
  The vast majority of global electricity comes from sources of heat, such as coal, gas, nuclear energy and concentrated solar energy. Some accounts put that number as high as 90% of our total electricity production. Steam turbines have been the industrial standard for converting such heat sources into

PSDcast – The Basics of Solar Clothing

Pvilion CEO Colin Touhey

­One area of renewable energy we haven’t really covered, at least as of yet, is the wearable sort – including and especially solar clothing that generates power while you go about your daily routine. But it’s still a technology with a ton of potential, and here to discuss that is Pvilion CEO Colin Touhe

Molten Salt Battery Could Provide Long-Term Energy Storage
The biggest downside of renewable energy is that we can’t control when the sun will shine or winds will blow. That factor alone ensure that renewable energy cannot supply all of our energy needs at the moment. Of course, there are other types of renewable generation that are more predictable, tidal energy and hydr

Figure 1. Typical B-H curve from positive saturation to negative saturation. When H is zero there exists Br which requires -Hc to return to zero. The area within the loop is core loss per cycle

What are AC Losses and why are they important? This paper discusses the physical effects and which issues must be observed by design engineers. Furthermore, an approach to determine AC losses with unmatched accuracy is being introduced. In 1892 Charles P. Steinmetz, working for General Electric presented his no
