Bezos i Gates investirali u projekt putničkog zrak

Avioni na električni pogon (s vodikovim gorivnim ćelijama) imaju i tu predsnost što stvaraju manju buku, pa nisu problem pri slijetanju kod kusto naseljenih mjesta. A što se tiče proizvodnje vodika, on bi se mogao proizvoditi na licu mjesta, takoreći na aerodromu, pa bi tako bio rješen i problem infrastrukture. 

 Dragi Vođa

Da su mi tvoji problemi da se naspavam. 

Onda imaš velik  kad Gates stane u njega. 

Već se odavno razvilo.

Čekamo slike ćejmtrejlza koji sukljaju iz aviona na vodik.

 Pa svi problemi s vodikom nestaju kada ga se kemijski uskladišti u obliku amonijaka. A amonijakom se danas rutinski barata kao sa ukapljenim plinom. I može se direktno sagorijevati u motorima s unutarnjim izgaranjem (bez štetnih ispuha) - ili se vodik pomoću katalizatora može ponovno izdvajati za PEM članke za proizvodnju el.energije. Jedini problem je što je amonijak poprilično otrovan za ljude, korozivan za neke metale, i nezgodan za okoliš, ali to je i benzin, pa smo naučili sigurno baratati njime (okej, tu-i-tamo se potkrade koja nesrećica pa se prolije, benzin naime) (inače amonijaka imamo i u mnogim sredstvima za čišćenje kućanstava).

Čak i trgovački brodoprevoznici, koji troše goleme količine fosilnih goriva, planiraju preći na mašine pogonjene amonijakom.

Jedino što još drži naftu kao glavni energent je to što ju je najjača globalna supersila vezala uz svoju valutu.

Još jedan Gatesov dijabolični plan: čipirana piletina za sirote Afrikance

no ipak ima nekih novih stvari: novi tehnološki procesi i jeftini lako proizvodljivi katalizatori primjenjivi u proizvodnji, razlaganju ili sagorijevanju amonijaka.

Energije zapravo ima u izobilju, ako se zna da samo u cca sat vremena površinu Zemlje sa Sunca oplahne toliko energije koliko čitava moderna civilizacija proizvede u godinu dana (koliko ono toplinske energije izražene kao hirošima-tip nuklearne bombe svjetski oceani apsorbiraju svake sekunde?). I očito je jeftiniji energent koji doslovno pada s neba od onoga oko kojega se prvo moramo pomučiti kroz gomilu tehnološki kompliciranih i energetski zahtjevnih procesa (i ja sam već pisao o tome i na ovom forumu, ali većini je promakla poanta)...
Mnoge stručne institucije nakon temeljitih istraživanja zaključile su već kako je sazrio čas za uvođenje amonijaka kao praktičnog pokretača naše civilizacije.


ARPA-E, or Advanced Research Projects Agency–Energy is a United States government agency tasked with promoting and funding research and development of advanced energy technologies. It is modeled after the Defense Advanced Research Projects Agency (DARPA).

We are enabling the storage of renewable energy as ammonia fuel by combining the development of a novel ammonia synthesis catalyst with process design focused on the variability in the renewable energy input. •Improved catalyst activity lowers power consumption ~35% due to operation at lower temperatures and pressures• Variable load control of the ammonia synthesis loop reduces gas/energy storage needs for use of renewable energy.

Compared to hydrogen as a fuel, ammonia is much more energy efficient, and could be produced, stored, and delivered at a much lower cost than hydrogen which must be kept compressed or as a cryogenic liquid.^[73][87]

Rocket engines have also been fueled by ammonia. The Reaction Motors XLR99 rocket engine that powered the X-15 hypersonic research aircraft used liquid ammonia. Although not as powerful as other fuels, it left no soot in the reusable rocket engine, and its density approximately matches the density of the oxidizer, liquid oxygen, which simplified the aircraft's design.

In early August 2018, scientists from Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) announced the success of developing a process to release hydrogen from ammonia and harvest that at ultra-high purity as a fuel for cars. This uses a special membrane. Two demonstration fuel cell vehicles have the technology, a Hyundai Nexo and Toyota Mirai.^[88]

In 2020, Saudi Arabia shipped forty metric tons of liquid "blue ammonia" to Japan for use as a fuel.^[89] It was produced as a by-product by petrochemical industries, and can be burned without giving off greenhouse gases. Its energy density by volume is nearly double that of liquid hydrogen.
If the process of creating it can be scaled up via purely renewable resources, producing green ammonia, it could make a major difference in avoiding climate change.^[90]
The company ACWA Power and the city of Neom have announced the construction of a green hydrogen and ammonia plant in 2020.^[91]

Green ammonia is considered as a potential fuel for future container ships.
In 2020 the companies DSME and MAN Energy Solutions announced the construction of an ammonia-based ship, DSME plans to commercialize it by 2025.^[92]

There were two studies done about ammonia for the 1980 US EPA Fuels Safety Report... After a careful comparison of hydrogen and ammonia, they wrote: “It is not understandable why hydrogen as a future fuel is widely promoted, whereas ammonia is presently not considered at all. The most likely explanation appears to be that the potential use of ammonia as a substitute fuel is just too unknown, even within the technical community.”

Some of the biggest supporters of ammonia are Japan’s biggest emitters of carbon dioxide, says Takeo Kikkawa, professor of management at the International University of Japan. “The electricity industry is particularly keen on ammonia. They have a lot of coal-fired plants that are highly cost-competitive but emit a lot of greenhouse gases. “If they can burn ammonia together with coal then they can reduce the criticism of those plants and keep them operating as long as possible.”

Ja ne znam jel to zato što je ovo primarno forum za kompjutoraše, pa je nemoguće razmišljati i analogno osim samo binarno, ili u čemu je problem?
Jel Zagreb sada kuri ležišta nafte, ugljena i plina na kojima leži? Ne mogu ti fotopaneli biti (osim na krovovima zgrada) i u nekom dalmatinskom osunčanijem kršu, ne ide neki dio sunčeve energije i u recimo vjetar koji manje-više konstantno puše po planinskim vrhuncima tipa Velebit ili po Bosni, zar ne bi mogli i uvozit vodik/amonijak iz Sahare recimo, kao što Japan planira iz Australije?
Ono, trošak za energent izvučen ispod smrznutog dna nekog dalekog oceana plus transport plus komplicirana i energetski zahtjevna obrada što sve zahtijeva i gigantsku infrastrukturu je nekim čudom konkurentniji drugom energentu koji doslovno neograničeno dolazi s neba? Pazi, ne radi se o električnim centralama, nego tek o pripremama da fosilno gorivo postane energent za centrale, industriju i transport.
Jedna Njemačka, koja je definitivno manje bogata priljevom obnovljivih po prosječnom kvadratu od Hrvatske, ali je u 2019. proizvela 237 TWh za javnu mrežu - udio veći nego od fosilnih - a ti pričaš o nekim tričavim gigavatima? I šta tu onda nije riješeno, osim u nečijim glavama?
