Sentences with phrase «oxygen and hydrogen during»

Rechargeable batteries are too heavy for the job, so engineers are planning to try a technology that would use current to separate water into oxygen and hydrogen during the day, and then reverse the process at night via fuel cells to produce electricity.

«In the round - the - clock process we produce hydrogen and electricity during daylight, store hydrogen and oxygen, and then when solar energy is not available we use hydrogen to produce electricity using a turbine - based hydrogen - power cycle,» Tawarmalani said.

During photosynthesis plants use solar energy to convert carbon dioxide and water into hydrogen - storing carbohydrates and oxygen.

Asteroids also contain an abundance of water, which, aside from serving as hydration during space travel, could be used as a shield to protect spaceships from the sun's radiation or to produce hydrogen - and oxygen - based rocket fuels.

By looking at the chemistry of rocks deposited during that time period, specifically coupled carbon and sulfur isotope data, a research team led by University of California, Riverside biogeochemists reports that oxygen - free and hydrogen sulfide - rich waters extended across roughly five percent of the global ocean during this major climatic perturbation — far more than the modern ocean's 0.1 percent but much less than previous estimates for this event.

During the Boring Billion, the planet's oceans were light on oxygen and heavy on toxic hydrogen sulfide.

The cloud consists of ionized gas, or plasma, and contains the elements hydrogen, helium, and oxygen, along with heavier elements that were generated during the blast itself.

A massive star creates huge amounts of oxygen and neon during its life and then hurls them into space when it explodes, so both elements are common: Oxygen is the third most abundant element in the universe, after hydrogen and helium, and neon ranks fifth or oxygen and neon during its life and then hurls them into space when it explodes, so both elements are common: Oxygen is the third most abundant element in the universe, after hydrogen and helium, and neon ranks fifth or Oxygen is the third most abundant element in the universe, after hydrogen and helium, and neon ranks fifth or sixth.

They think this involves oxygen and hydrogen atoms formed during or after the etching process, which attach themselves to the internal surface of the porous structure.

For example, by mixing about six metric tons of hydrogen (a surplus of hydrogen could be taken aboard for this reason) with carbon dioxide, a chemical processor could create enough methane and oxygen to propel the vehicle during liftoff and the trip back to Earth.

At electrical breakdown, the energies in the surging electrons were thousands of times greater than 10 — 19 MeV, so during the flood, bremsstrahlung radiation released a sea of neutrons throughout the crust.83 Subterranean water absorbed many of these neutrons, converting normal hydrogen (1H) into heavy hydrogen (2H, called deuterium) and normal oxygen (16O) into 18O.

Incidentally, how would the net btu's / acre achieved by ethanol production (if any) compare to the btu's / acre that could be achieved by using solar cells to electrolyze water during sun hours, then burning the hydrogen and oxygen in a conventional steam plant 24/7 at a rate slightly less than the average rate of O2 / H2 production?

I am assuming that during Ice Ages, CO2 was very low due to the oxygen being locked in ice which is H2O, that is, one oxygen molecule and two hydrogen.
