   ”The mineral in your bones is called hydroxyapatite and has the chemical formula Ca5(PO4)3(OH). Our bodies build bone mineral on the spot, so we don’t have to swallow hydroxyapatite crystals. But we do have to eat food with enough of the right kinds of atoms to build bone mineral”

   ”Minerals can also form in the human body as part of disease states such as in kidney stones”

   ”Tuotantoprosessi jaetaan louhintaan, murskaukseen, biokasaliuotukseen ja metallien talteenottoon.”
   🚙⚡⚡🔋🚗🛴🛵⚰️
   ”Metallit liukenevat kasassa jatkuvasti kiertäviin liuoksiin, kunnes liuos saavuttaa halutun metallipitoisuuden ja se otetaan talteen. Bioliuotus tapahtuu primääri- ja sekundäärikasoissa, joissa ensimmäisessä bioliuotus kestää 13 kuukautta ennen siirtymistä sekundäärikasaliuotukseen. Viimeisessä tuotantovaiheessa metallien talteenotossa biokasaliuotuksesta saatu metallipitoinen liuos saostetaan rikkivedyn avulla, minkä jälkeen metallituoteseos myydään markkinoille.”
   🚙⚡⚡🔋🚗🛴🛵⚰️
   ”Kasoja ilmastetaan ja kastellaan happamalla (pH 1,5–3) liuoksella kasan päällä olevien kasteluputkien avulla bakteeritoiminnan kiihdyttämiseksi, jolloin vapautuu runsaasti lämpöä. Bioliuotus on luonnollinen prosessi teollisessa mittakaavassa. Siinä bakteerit erottavat metallit malmista katalysoimalla malmin sisältämän raudan ja rikin hapettumista saadakseen energiaa kasvuunsa. Halutulla liuoksen pH:lla varmistetaan maksimaalinen metallien liukeneminen malmista, mutta estetään epäpuhtauksien liukeneminen.”
   🚙⚡⚡🔋🚗🛴🛵⚰️
   ”Bioliuotuksessa käytetään vettä, ilmaa sekä kotoperäisiä bakteereja, jotka kasvavat malmissa luonnostaan. Prosessi on Talvivaaran mukaan kustannuksiltaan edullinen, sillä sen vaatimat investoinnit ja käyttökustannukset ovat pienemmät kuin perinteisillä sulatus- ja jalostusprosesseilla, minkä lisäksi bioliuotuksen ilmoitetaan olevan puhtaampi ja ympäristöystävällisempi menetelmä. Bioliuotus vaatii myös vähemmän energiaa kuin perinteiset jalostusprosessit.”

   ”The system has a unique advantage in the ability to passively capture hydrogen from industrial flues and waste treatment plants before it can bond to form greenhouse gases.”

   ”Without magnesium we could not produce energy” ”All organic matter—plants, animals, and the human body—is made up of combinations of elements such as such as oxygen, carbon, and hydrogen.”
   🚙⚡⚡🔋🚗🛴🛵⚰️
   ”Magnesium is a macro-mineral, which, unlike trace minerals, is needed by the body in large amounts. Calcium, sodium, and potassium are also macro-minerals. The average human body contains about 25 grams of magnesium, one of the six essential minerals that must be supplied in the diet.”

   ”Magnesium hydride, MgH2, has drawn widely attention as option for hydrogen storage. Main benefits are its abundant resource, high performance, light weight, low-cost, and safety. In comparison to other hydrides usable for hydrogen storage, MgH2 has the highest hydrogen storage densities with up to 7.6 wt %.”

   ”Hydrolysis produces about as much energy as PEMs give off in the form of waste heat, i.e., approximately 1 kilowatt of heat per kilowatt of electrical output, at a temperature of around 80 °C. The most sensible course of action would thus be to devise a plan for the shared thermal management of both the fuel cell and the hydrolysis reactor.”

   ”Its specific energy is 6.1 kWh per kilogram, PowerPaste’s being 3.8 kWh. Even when factoring in fuel cell losses, the material provides much more energy than today‘s batteries, the gravimetric energy density of which is around 0.2 kWh per kilogram.
   The magnesium to make magnesium hydride and PowerPaste is already available on the market in large quantities, at a raw material price of around EUR 1.70 a kilogram. Magnesium is also not a rare element but the third-most common in the earth’s crust.
   According to IFAM estimates, even magnesium produced by conventional means will, over the longer term, lower the price of making PowerPaste to around EUR 2 to EUR 3 a kilogram. The levelized cost will be around EUR 20 to EUR 30 per kilogram at the point of use, including all expenditures for infrastructure and distribution. This reflects the full cost of production as opposed to artificial prices for hydrogen at fueling stations.”

In the case of e-scooters, however, installation of a high-pressure tank to store the hydrogen is impractical. An alternative here is POWERPASTE.”
