Tapping the Energy of the Tides Speaker:        Concerns over global warming have scientists and engineers looking for cleaner alternative sources of energy. One of those alternatives gaining momentum [1] involves harnessing the energy of the ocean. Renewable energy experts say in theory, energy from tides, currents , and waves could double the hydropower [2] output in the US, producing 20 percent of the nation’s electricity. But the technology to capture this renewable energy is in its infancy. NHPR’s Amy Quinton reports on the effort in New Hampshire’s seacoast to tap the power of the tides. Jack Pare:      Coming in, it hits this shore pretty heavy; going out, it hits the Newington shore pretty heavy. Uh, it is a dramatic roar. It really is. Quinton:         Jack Pare, a retired aerospace systems engineer, points to the water under the General Sullivan and Little Bay Bridge in Dover. He ...

Energy: What’s the Least Worst Option? David Shukman: Protests about power. How we get it, where it comes from. Why is everyone so angry about energy? I’ve come to Yorkshire, a land where the rocks hold rich seams of coal [1] and where the winds race over the hills offering a very different sort of power. No single kind of energy can answer all of our needs. We have a mix and the question is how that should change. The challenge with energy is that each type of it has pros and cons. Burning coal gives us 40% of our electricity. It is cheap and also very polluting. Burning gas gives us 30%. It’s much cleaner but we either import the stuff or frack it out of the ground here in Britain. Nuclear offers a nice, steady 20%, but it is expensive. Which leaves renewables like wind, it’s intermittent , there’s no pollution, but who would actually want one of these right on their doorstep? So, those are the choices. What do we want? So how to decide what’s right? Gary Smith is the con...

Change Is in the Making Kevan Gilbert: Welcome to Change is in the Making , Domain7’s podcast where we explore all things digital through the lens of purposeful change. I’m Kevan Gilbert. Veronica Collins: And I’m Veronica Collins, and together, we’ll be discussing themes of connection making and culture shaping. We’ll be delving into [1] how to create meaningful change from a business standpoint and a human perspective. Gilbert:           Today, we’re looking at the exploding reality of quote, unquote “digital transformation.” . . . Collins:           But I saw somebody call it a digital revolution the other day instead of digital transformation, and that really seems to ring true, that we’re living through, in the same way that the Industrial Revolution [2] completely reorganized people’s lives. We’re living through a digital transformation in that way— Gilbert:   ...

The Reindeer People Narrator:        We were all once nomads; but in the central Asian nation of Mongolia, many of the people still are. Herders are constantly on the move, finding fresh grasses for their animals. Mongolia’s geography, a boundless wilderness with soil that can’t sustain agriculture, forces people to embrace the nomadic life. Sanjeem is a nomadic reindeer [1] herder. He and his people are caught between two worlds. Theirs, and one in which Mongolia’s urban elite calls on nomads to settle . Sanjeem sits, mounted on one reindeer, and drives about 50 others with coats of white and mottled charcoal up a rock-strewn grassy slope. Sanjeem (via interpreter): Our ancestors have herded reindeer here in mountains of Mongolia for generations. We keep our animals here, and we actually follow our reindeer where they want to go because the environment and the climate are perfectly suited to our reindeer. This is the basis of our culture. N...
