Why a hydrogen economy doesn't make sense

In a recent study, fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful economy. The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package ...

Zinc Powder Will Drive Your Hydrogen Car

A revolutionary method of using concentrated solar energy for producing hydrogen in a clean, safe and inexpensive way was developed by a cooperation of scientists from Israel, Sweden, Switzerland and France. This new method, ...

How 'the strong force' influences the gravitational wave background

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

Hiroshima fallout debris linked to first solar system condensates

The atomic bombing of Hiroshima, Japan, by the United States in August 1945 was not only devastating at the time, resulting in the deaths of hundreds of thousands of people, but it has had long-standing impacts to the present ...

Possible atmospheric destruction of a potentially habitable exoplanet

Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the ...

The comprehensive characterization of hydrogen at ultra-high pressures

Physicists and material scientists have been trying to metallize hydrogen for many decades, but they have not yet succeeded. In 1968, British physicist Neil Ashcroft predicted that atomic metallic hydrogen would be a high-temperature ...

Physicists create first direct images of the square of the wave function of a hydrogen molecule

For the first time, physicists have developed a method to visually image the entanglement between electrons. As these correlations play a prominent role in determining a molecule's wave function—which describes the molecule's ...

Scientists address many-electron problem by modeling an infinite chain of hydrogen atoms

(Phys.org)—For the first time, scientists have determined the equation of state of an infinite chain of hydrogen atoms, which tells the amount of energy each hydrogen atom has, given the bond length between adjacent atoms.

Electricity from seawater: New method efficiently produces hydrogen peroxide for fuel cells

(Phys.org)—Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that ...

Tiny filters, big news: Novel process uses graphene and boron nitride monolayers to separate hydrogen ion isotopes

(Phys.org)—Conventional membranes used for sieving atomic and molecular species cannot scale to the subatomic level, making them unable to separate hydrogen isotope ions (protons, deuterons and tritons). At the same time, ...
