Giant game of real-life pong, anyone?

Here is a prototype of a giant pong-inspired game called GRiD, by multimedia entertainment creators Moment Factory. But rather than facing a screen, you are facing humans, in a physically challenging real-world game.

According to engadget:

Moment Factory has created GRiD, a Pong variant that uses a LiDAR sensor (the same tech as in self-driving cars) to create an enormous, 40-by-60 foot playing field where the paddle only moves when you and a partner shuffle your feet together. You could get quite the workout if the teams are evenly matched, and that's before the game adds wrinkles like surprise acceleration or an extra ball.

GRiD isn't available to the public quite yet, but when it is I'll be standing in line. Read the rest

Cost savings of renewable energy might outweigh costs of adapting to renewable energy

Producing power from the wind and sun isn't as simple as just swapping a wind turbine for a coal-fired power plant. Every source of power we use has to work with our electrical grid, an old, imperfect, complex system that wasn't put together with the needs of renewables in mind. For instance, because renewable generation is intermittent generation, using it goes hand-in-hand with ramping production from traditional generation up and down. When you don't have enough wind, you turn up the gas-fire generators. That kind of treatment can put stress on machinery and rack up costs in maintenance and repairs. But new research from the National Renewable Energy Laboratory suggests that, at least in monetary terms, those costs are dwarfed by the cost savings you get from using more wind and solar power and, thus, not having to pay for fuel sources.

Blackout: What's wrong with the American grid

It began with a few small mistakes.

Around 12:15, on the afternoon of August 14, 2003, a software program that helps monitor how well the electric grid is working in the American Midwest shut itself down after after it started getting incorrect input data. The problem was quickly fixed. But nobody turned the program back on again.

A little over an hour later, one of the six coal-fired generators at the Eastlake Power Plant in Ohio shut down. An hour after that, the alarm and monitoring system in the control room of one of the nation’s largest electric conglomerates failed. It, too, was left turned off.

Those three unrelated things—two faulty monitoring programs and one generator outage—weren’t catastrophic, in and of themselves. But they would eventually help create one of the most widespread blackouts in history. By 4:15 pm, 256 power plants were offline and 55 million people in eight states and Canada were in the dark. The Northeast Blackout of 2003 ended up costing us between $4 billion and $10 billion. That’s “billion”, with a “B”.

But this is about more than mere bad luck. The real causes of the 2003 blackout were fixable problems, and the good news is that, since then, we’ve made great strides in fixing them. The bad news, say some grid experts, is that we’re still not doing a great job of preparing our electric infrastructure for the future. Read the rest

Meet the people who keep your lights on

Power was restored today in India, where more than 600 million people had been living without electricity for two days. That's good news, but it's left many Americans wondering whether our own electric grid is vulnerable.

Here's the good news: The North American electric grid is not likely to crash in the kind of catastrophic way we've just seen in India. I'm currently interviewing scientists about the weaknesses in our system and what's being done to fix them and will have more on that for you tomorrow or Friday.

In the meantime, I wanted to share a chapter from Before the Lights Go Out, my book about electric infrastructure and the future of energy. If you want to understand why our grid is weak, you first need to understand how it works. The key thing to know is this—at any given moment, in any given place, we must have an almost perfect balance between electric supply and electric demand. Fluctuations of even fractions of a percent can send parts of the system towards blackout.

More importantly, that careful balance does not manage itself. Across North America there are people working, 24-7, to make sure that your lights can turn on, your refrigerator runs, and your computer works. They're called grid controllers or system operators. Most utility customers have never heard of these guys, but we're all heavily dependent on them. They keep the grid alive and, in turn, they keep our lives functioning—all without the benefit of batteries or any kind of storage. Read the rest

India's in the dark, are we next?

670 million people—roughly half of India's population—has been without electricity for two days, following a massive blackout. The United States has a much more modern grid, but only nine years ago a blackout in the Northeast of this country cut power to 45 million. How does a huge blackout like that happen? What are we doing to prevent another one? I'll be on Southern California Public Radio's Madeline Brand Show this morning to talk about how America's electric grid works ... and doesn't work. The show starts at 9:00 Pacific time and I'll be on around the top of the hour. Read the rest

The dirtiest wind power in America

In the left-hand corner of this photo, towards the back of the shot, you can see what researchers at Colorado State University jokingly call "the dirtiest wind power in America."

In reality, it's a diesel-powered electric generator—just a smarter version of the kind of machine that you might kick on at your house during a blackout. But this dirty diesel is actually helping to make our electric grid cleaner. This room is a smart grid research laboratory, a place where scientists and engineers learn more about how wind and solar power affect our old electric infrastructure, and try to develop systems that will make our grid more stable and more sustainable.

They use this diesel generator to model wind power on a micro-grid. The electricity produced by a wind farm doesn't enter the grid as a steady, flat signal. Instead, it fluctuates, oscillating up and down with shifts in wind currents. The diesel generator can mimic those patters of electricity production. With it, Colorado State researchers can study the behavior of wind currents all over the United States without having to have labs in all those places. They can also recreate wind events that have already happened—like a major storm—to find out how that event affected the grid and learn how to better adapt the grid to future situations.
