Globally, energy demand from computing is growing so fast the search is on to find fundamental ways to make it more efficient. “Magnetisation switching” has long been seen as a more efficient way than using transistors to create the 1s and 0s in memory chips and processors. But existing solutions operate only at very low temperatures. Also, they are controlled by magnetic fields which are harder to manage than switches controlled electrically. … [Read more...]
Compact voltage converters for integrating new DERs into the grid
The switches and converters needed to plug new clean energy technologies into the grid are going to be needed soon. The cheaper and smaller they are, the easier it will be to cope with the wide range of solutions coming down the pipe. NREL and its partners are building a megawatt-scale prototype converter that could fit the bill. They will be 1/5th the size and 1/10th the weight of existing alternatives: small enough to place almost anywhere. … [Read more...]
