The conference, hosted in Dallas by the U.S. Chilldyne optimized the cold plate using corkscrew-shaped metal channels, called turbulators, that force water around them “like little tornadoes,” maximizing the heat absorbed, says Harrington. Emrgy estimates that there are more than 160,000 kilometers of these waterways in the country.

Digital Twins Give Hydrogen a Greener Path to Growth

Cars That Think

It burns clean, generating only water as a by-product, and when it’s produced through electrolysis by splitting water into hydrogen and oxygen, the entire life cycle can be very environmentally friendly. Service-oriented architectures are also fast enough to support the live bidirectional data connection needed by electrolyzers.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

That need for balance is true of electric power grids, too. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. Packetized energy management (PEM) allows the power grid to flexibly handle a varying supply of renewable energy. Here’s how.

The Business of Plugging In: Building the Full Ecosystem for a Successful Plug-in Vehicle Industry in the US

Green Car Congress

The conference was sold out; it was also essentially a PowerPoint-free zone; the basic format relied heavily on brief introductory remarks from sets of speakers representing the diverse stakeholders, followed by questions from attendees. The impact from plug-in electric vehicles on the grid could be very substantial.
