Renewable energy doesn’t always mean what you think

When you think of renewable energy, what comes to mind? Wind, solar. Wind power Wind energy, solar energy Solar panels, wind farms How about hydroelectric? Hydroelectric? Yeah. I would say yes. Burning wood? No? I think technically it’s a renewable energy. Burning trash? No? I feel like it’s a trick Hmm Depending on the state, […]

‘More electricity to come from renewables than fossil fuels in 2019’

Britain will produce more electricity from zero carbon energy sources sources than fossil fuels in 2019, experts from the National Grid predict If true, this will be the first time since the Industrial Revolution that this has been the case, they say The feat will be achieved through greater reliance on cleaner energy sources, it’s claimed […]

Space Mirrors and Other Weird Ways to Fight Climate Change

Today on Reactions: craziest ideas to combat climate change. Let’s do this. First up: massive gigantic enormous space mirrors. The Sun is constantly emitting all kinds of light — including visible, ultraviolet, and infrared— which heat up the Earth. A space mirror is designed to cast a small shade on the Earth and reduce the […]

Carbon Nanotubes Might Be the Secret Boost Solar Energy Has Been Looking For

Solar panels are an incredible innovation in energy tech, but they’re way less efficient than they could be, because they have a problem: heat. Specifically, waste heat, or energy that’s lost while converting the sun’s energy into electricity. But a new technology—made possible by carbon nanotubes—may be just the thing that brings solar panels into […]

‘Diamond-age’ of power generation as nuclear batteries developed

Since the 1940s, the UK has run many nuclear reactors, for research, military purposes and electricity generation. These reactors use uranium as fuel, housed inside of a core made of graphite blocks. This graphite core assists in the nuclear fission process, enabling a controllable chain reaction which provides a constant source of heat. This heat […]

UQx DENIAL101x 6.7.4.1 Full interview with Michael Ranney

My name is Michael Ranney. I’m a professor here at the University of California at Berkeley. I tend to do research on things that basically are the intersection of three different realms: one realm is science cognition; the other one is about mathematical cognition, particularly numeracy; and, finally, I’m also interested in things that are […]

Where does gold come from? – David Lunney

In medieval times, alchemists tried to achieve the seemingly impossible. They wanted to transform lowly lead into gleaming gold. History portrays these people as aged eccentrics, but if only they’d known that their dreams were actually achievable. Indeed, today we can manufacture gold on Earth thanks to modern inventions that those medieval alchemists missed by […]

Lightbulbs in the Desert (Powering the Planet)

Narrator: Planet Earth is awash in renewable energy. The oceans store heat and offer wave and tidal power. Plants harvest sunlight and store its energy. The Sun warms the atmosphere and sets air in motion, and we’re getting better at tapping wind power. But the biggest and most promising energy source is the nearby star […]
