Salinity - The concentration of salt in a solution. So a 100ml of water with 3.5g of Sea Salt is what nutrition you get in that picture. Growing well. Not going to top or do any training, I'll let the plant do its own thing, building foundations now for what it senses ahead. Smart girl. ✨️ The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity." Electrolysis. Electrolysis of water is using electricity to split water into oxygen (O2) and hydrogen (H2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurized into convenient 'tanks' or 'gas bottles', hydrogen can be used for oxyhydrogen welding and other applications, as the hydrogen/oxygen flame can reach approximately 2,800°C. Green hydrogen is hydrogen produced by the electrolysis of water, using renewable electricity. The production of green hydrogen causes significantly lower greenhouse gas emissions than the production of grey hydrogen, which is derived from fossil fuels without carbon capture. Electrolysis of pure water requires excess energy in the form of overpotential to overcome various activation barriers. Without the excess energy, electrolysis occurs slowly or not at all. This is in part due to the limited self-ionization of water. Pure water has an electrical conductivity of about one hundred thousandths that of seawater. Efficiency is increased through the addition of an electrolyte (such as a salt) Photoelectrolysis. Photoelectrolysis of water, also known as photoelectrochemical water splitting, occurs in a photoelectrochemical cell when light is used as the energy source for the electrolysis of water, producing dihydrogen which can be used as a fuel. Photoelectrolysis is sometimes known colloquially as the hydrogen holy grail for its potential to yield a viable alternative to petroleum as a source of energy. The PEC cell primarily consists of three components: the photoelectrode the electrolyte and a counter electrode. The semiconductor crucial to this process, absorbs sunlight, initiating electron excitation and subsequent water molecule splitting into hydrogen and oxygen. Water electrolysis requires a minimum potential difference of 1.23 volts, although at that voltage external heat is also required. Typically 1.5 volts is required. Biochar, a by-product of biomass pyrolysis, is typically characterized by high carbon content, aromaticity, porosity, cation exchange capacity, stability, and reactivity. The coupling of biochar oxidation reaction (BOR) with water electrolysis constitutes biochar-assisted water electrolysis (BAWE) for hydrogen production, which has been demonstrated to reduce the electricity consumption of conventional water electrolysis from 1.23v to 0.12v. Biochar particles added to the electrolyte form a two-phase solution, in which the biochar oxidation reaction (BOR) has a lower potential (0.21 V vs. RHE) than OER (1.23 V vs. RHE), reducing the energy consumption for hydrogen production via biochar-assisted water electrolysis (BAWE). BAWE produces H2 under 1 V while eliminating O2 formation: The addition of ion mediators (Fe3+/Fe2+) significantly increases BOR kinetics Air: Nitrogen -- N2 -- 78.084% Carbon Dioxide -- CO2 -- 0.04% Hydrogen -- H2 -- 0.00005% "Nitrogen, oxygen, and argon are the three main components of Earth's atmosphere. Water concentration varies but averages around 0.25% of the atmosphere by mass. Carbon dioxide and all of the other elements and compounds are trace gases. Trace gases include the greenhouse gases carbon dioxide, methane, nitrous oxide, and ozone. Except for argon, other noble gases are trace elements (these include neon, helium, krypton, and xenon). Industrial pollutants include chlorine and its compounds, fluorine and its compounds, elemental mercury vapor, sulfur dioxide, and hydrogen sulfide. Other components of Earth's atmosphere include spores, pollen, volcanic ash, and salt from sea spray." Although the CRC table does not list water vapor (H2O), air can contain as much as 5% water vapor, more commonly ranging from 1-3%. The 1-5% range places water vapor as the third most common gas (which alters the other percentages accordingly). Water content varies according to air temperature. Dry air is denser than humid air. However, sometimes humid air contains actual water droplets, which can make it more dense than humid air that only contains water vapor. "salt from sea spray" in the air, cool, so like how much air do I need to run through my medium to collect this sea spray you reckon? The homosphere is the portion of the atmosphere with a fairly uniform composition due to atmospheric turbulence. In contrast, the heterosphere is the part of the atmosphere where chemical composition varies mainly according to altitude. The lower portion of the heterosphere contains oxygen and nitrogen, but these heavier elements do not occur higher up. The upper heterosphere consists almost entirely of hydrogen, cool. Just run me a hose up to the heterosphere and I'm good then.
