Energy Technology
Solar power has the disadvantage that there's no Sun at night. Satellite startup Reflect Orbital wants to change that, but at what cost?
There are real concerns with long-term power generation on the Moon; nuclear could be the answer. But for NASA, will the cost be too high?
For well over a century, engineers have proposed harnessing the ocean’s tides for energy. But the idea hasn’t seemed to register in many places.
The futuristic weapon could be ready for the battlefield in 5 years.
These theoretical megastructures represent one way an advanced civilization might harvest energy from stars.
Analog could serve as "always-on" computing, while digital is turned on only when necessary.
Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.
A massive nuclear fusion experiment just hit a major milestone, potentially putting us a little closer to a future of limitless clean energy.
LK-99, almost certainly, isn't a room-temperature superconductor. The underlying physics of the phenomenon helps us understand why.
Ironically, the company did so using technology perfected by the oil industry.
The material is both stronger and lighter than those used to make conventional power plant turbines.
What if we could harvest energy from human heat, sweat, or vibrations?
Apart from the energy needed to flip the switch, no other energy is needed to transmit the information.
Innovative thinking has done away with problems that long dogged the electric devices — and both scientists and environmentalists are excited about the possibilities.
Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won't.
The shift from steam to electricity was inevitable — but some foresaw it earlier than others.
Lithium-ion batteries pose challenges for our transition toward renewable energy. Sodium-sulfur batteries might be a solution.
Don't put all your eggs in one basket.
Its implications go well beyond the Earth itself, affecting even the future of space travel.
Nuclear fusion has long been seen as the future of energy. As the NIF now passes the breakeven point, how close are we to our ultimate goal?
If you gave me $400 and I gave you $3.15, would you consider yourself wealthier? That's a financial analogy for the supposed fusion power "breakthrough."
Really simple interventions can greatly reduce indoor temperatures during the summer, particularly in places like the Pacific Northwest.
It could make enough drinking water for a family of four.
Wind energy is one of the cleanest, greenest sources of power. But could it have the sneaky side-effect of changing the weather?
It has no moving parts and could allow us to tap into renewable energy year round.
In a major advance, scientists have found a new and groundbreaking way to force electrons to flow only in one direction in a superconductor.
A lucky discovery involving lithium-sulfur batteries has a legitimate chance to revolutionize how we power our world.
Why power generated through nuclear fusion will be the future, but not the present, solution to humanity's energy needs.
Wireless charging isn't just for phones and laptops. It could also power medical devices like heart implants.
And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]
