Ironically, the company did so using technology perfected by the oil industry.
Decades ago, a disaster left three million acres of land uninhabitable and killed between 85,600 and 240,000 people. Chernobyl? No. Banqiao dam in China.
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.
Experiments on suborbital rockets are revealing how to make a better iron furnace.
Explore data on electric car sales and stocks worldwide.
Apart from the energy needed to flip the switch, no other energy is needed to transmit the information.
The term “zero-point energy” has at least two meanings, one that is innocuous and one that is a great deal sexier (and scammier).
A new hypothesis accuses the simple sugar of wrecking energy metabolism.
Einstein’s most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
The material is both stronger and lighter than those used to make conventional power plant turbines.
Quantum mechanics has taught us that even empty space contains energy. “Negative energy” is the state of having less energy than empty space.
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.
There may be more energy in methane hydrates than in all the world’s oil, coal, and gas combined. It could be the perfect “bridge fuel” to a clean energy future.
You are an energy field — but not the “chakras” or “auras” kind.
The robot can drive heavy steal beams into the ground at a rate of 1 per 73 seconds, which will help expedite solar farm construction.
When leaders embrace positive personal energy, everyone feels the benefits — in trust, innovation and creativity.
Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won’t.
Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid “having to live with it?”
The futuristic weapon could be ready for the battlefield in 5 years.
The galactic center is home to the most powerful engine in the Milky Way: a supermassive black hole. How does its energy ultimately escape?
These theoretical megastructures represent one way an advanced civilization might harvest energy from stars.
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?
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
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 new measurement offers insights on the density of the mysterious force driving the Universe’s expansion.
Here’s what recent DESI measurements suggest — and why it’s too early to update conventional predictions about the Universe’s distant future.
Energy balance is the greatest arbiter of weight gain. Embrace the “oinker diet.”
The standard picture of our Universe is that it’s dominated by dark matter and dark energy. But this alternative is also worth considering.
