Ironically, the company did so using technology perfected by the oil industry.
Apart from the energy needed to flip the switch, no other energy is needed to transmit the information.
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.
Quantum mechanics has taught us that even empty space contains energy. "Negative energy" is the state of having less energy than empty space.
Experiments on suborbital rockets are revealing how to make a better iron furnace.
Einstein's most famous equation is E = mc², which describes the rest mass energy inherent to particles. But motion matters for energy, too.
A new hypothesis accuses the simple sugar of wrecking energy metabolism.
All forms of energy affect the expanding Universe. But if matter and radiation slow the expansion down, how does dark energy speed it up?
The term "zero-point energy" has at least two meanings, one that is innocuous and one that is a great deal sexier (and scammier).
The material is both stronger and lighter than those used to make conventional power plant turbines.
You are an energy field — but not the “chakras” or “auras” kind.
Capacitors, acid batteries, and other methods of storing electric charges all lose energy over time. These gravity-fed batteries won't.
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.
Explore data on electric car sales and stocks worldwide.
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.
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?
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.
They are expected to be cheaper to build and even more reliable than today’s nuclear plants.
Energy balance is the greatest arbiter of weight gain. Embrace the "oinker diet."
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.
The zero-point energy of empty space is not zero. Even with all the physics we know, we have no idea how to calculate what it ought to be.
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.
Early on, only matter and radiation were important for the expanding Universe. After a few billion years, dark energy changed everything.
A new measurement offers insights on the density of the mysterious force driving the Universe's expansion.
McDermitt Caldera, the site of an ancient volcanic eruption, straddles the border of Oregon and Nevada.
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
For every proton, there were over a billion others that annihilated away with an antimatter counterpart. So where did all that energy go?
