Amplifying the energy within a laser, over and over, won't get you an infinite amount of energy. There's a fundamental limit due to physics.
Let's celebrate the progress, but put the cork back in the champagne bottle.
By digging deep, we could harness enough energy to power generations to come. But it involves fracking.
This company uses thousands of mirrors, AI, and machine learning to unlock the power of the sun.
Best in class: Denmark and Uruguay. Worst in class: Papua New Guinea, Venezuela, and Russia.
Dr. Tyson explains where we might find aliens, why "dark matter" is a misleading term, and why you can blame physics for your favorite team's loss.
A community in Austin, Texas is using geothermal energy to keep homes warm in the winter and cool in the summer.
Scientists are solving the problem of costly energy storage.
It has no moving parts and could allow us to tap into renewable energy year round.
You might think it's impossible to run out of wind, but Europe's "wind drought" proves otherwise. And it's only going to get worse.
A team of scientists hopes deep-earth lithium could sustain America's vast demand for batteries. But extracting it won't be easy.
“I thought, why not direct these high-power beams, instead of into fusion plasma, down into rock and vaporize the hole?”
A "bio-battery" made from genetically engineered bacteria could store excess renewable energy and release it as needed.
Over time, the Universe becomes less dominated by dark matter and more dominated by dark energy. Is one transforming into the other?
Now they're pointing the way to future battery technologies.
The Kardashev scale ranks civilizations from Type 1 to Type 3 based on energy harvesting.
Could Russia's plan actually destroy demand for natural gas?
The idea of gravitational redshift crossed Einstein's mind years before General Relativity was complete. Here's why it had to be there.
The power tower has superior physics but inferior economics.
Smashing things together at unprecedented energies sounds dangerous. But it's nothing the Universe hasn't already seen, and survived.
More than any other of Einstein's equations, E = mc² is the most recognizable to people. But what does it all mean?
Realizing that matter and energy are quantized is important, but quantum particles isn't the full story; quantum fields are needed, too.
Wind energy is one of the cleanest, greenest sources of power. But could it have the sneaky side-effect of changing the weather?
