Philip Rosedale, the Willy Wonka of virtual reality, is giving me a tour of his bustling office in San Francisco in August when his blue eyes sparkle with a better idea. “Let’s just go in-world instead,” he suggests. I follow him to a windowless back room. Waiting there for us are a large HDTV screen, a computer, a few cardboard boxes, and two small, black infrared light-emitting beacons that point down from the high corners.

2022—The Year the Hydrogen Economy Launched?

The Inflation Reduction Act and the war in Ukraine pump billions into clean hydrogen R&D

Among the technological visions that seem perpetually futuristic (think commercial nuclear fusion and maglev trains), the hydrogen economy has always been tantalizing. Hydrogen produced from renewable energy or nuclear power, with minimal greenhouse-gas emissions, could be piped or transported pretty much anywhere, using mostly existing infrastructure. It could power trucks, cars, planes, and ships and generate electricity, either in fuel cells or combustion turbines. In short, it could do anything fossil fuels do now, but with substantially reduced climate impact.

Now, after decades of false starts and overly optimistic projections, several factors are giving an unprecedented lift to clean hydrogen. In the United States, sweeping legislation capped a series of moves by the country’s Department of Energy (DOE) over the past year to drive down the cost of low-carbon hydrogen and stimulate demand for the fuel. And in Europe, a looming fossil-fuel crisis has sent officials scrambling to find alternatives to the 155 billion cubic meters of Russian natural gas that EU countries imported in 2021.

Q&A: Marc Raibert on the Boston Dynamics AI Institute

The founder of Boston Dynamics talks with us about the new $400 million research institute

Last week, Hyundai Motor Group and Boston Dynamics announced an initial investment of over $400 million to launch the new Boston Dynamics AI Institute. The Institute was conceptualized by (and will be led by) Marc Raibert, the founder of Boston Dynamics, with the goal of “solving the most important and difficult challenges facing the creation of advanced robots.” That sounds hugely promising, but of course we had questions—namely, what are those challenges, how is this new institute going to solve them, and what are these to-be-created advanced robots actually going to do? And fortunately, IEEE Spectrum was able to speak with Marc Raibert himself to get a better understanding of what the Institute will be all about.

As 5G evolves into 6G networks, it will be critical that it adopt the most energy-efficient technologies to reduce carbon emissions and our dependence on non-renewable resources.

In terms of increased sustainability, 6G will need to aim directly at lessening its overall environmental impact, including water consumption, raw material sourcing, and waste handling. But it is also important to consider the indirect impact of 6G networks can have on sustainability by conserving resources and minimizing waste in either existing use-cases or novel use-cases.
