New Zealand Designer Makes Ingenious Solar-Powered Skylight That Desalinates Water For Drinking

Goglau’s device can purify 440 milliliters of water a day, with leftover brine being sifted into batteries made of zinc and copper where they power an LED strip for use during the night.

finalist in the 2021 Lexus Design Award, Henry Glogau, has created something that takes advantage of both these abundant resources: a solar-powered lighting fixture that desalinates water.

Nekonečná téma "psychológie klimatickej krízy". Je notoricky známe, že široká verejnosť hrubo podceňuje (ignoruje/zlahčuje/zosmiešňuje/relativizuje) následky oteplovania. Čo si niektorí zase interprerujú tak, že "klimatológovia desaťročia neúspešne strašia", veď inak by sme už všetci chápali, že Houston má problém.

Príčin, prečo dlohodobo nie sme schopní racionálne reagovať (individuálne ani kolektívne) na túto existenčnú hrozbu, je viacero. V zásade ide o súbor nevedomých, evolučne podmienených inštinktov, ktoré našim predkom, a ich predkom (až smerom k prvému živému organizmu), zabezpečili prežitie v nekonečnom konkurenčnom darwinovom boji "prežitia silnejšieho", ak chcete inak, automatickej reakcie, ktorú nedokážeme svojou "slobodnou vôlou" (tj. vedomým rozhodnutím) ovplyvniť.

A tak, vo svetle najväčšej ekologickej hrozby histórie ludstva "slepo" kráčame k pomyslnému útesu. Hladáme si rôzne výhovorky, prečo útes neexistuje (popieranie klimatickej krízy), alebo "riešenia" ako pád z útesu prežijeme (technooptimizmus/odletíme na Mars). To všetko len odráža našu nemožnosť (nie neschopnosť) racionálne reagovať tak, ako je potrebné.

Psychológovia budú hladať cesty, ako von zo "začarovaného kruhu", ale je to podobné, ako sa snažiť pochopiť, prečo papagáj nerozumie teórii relativity (bez urážky) a potom sa snažiť mu ju vysvetliť.

Klimatická kríza je neriešitelný problém.

SHEFIK: Tak to spocitej, kolik ha solaru na to potrebujes ..

TADEAS: to znamena, ze renewables musi v australii vyrobit neco jako 200gwh na jednu lod. tech lodi ve vysledku asi moc potreba nebude :)

SHEFIK: 2000 tun by melo bejt neco jako 66.6 GWh ,)

tak snad do slibenejch 5ti let

Australian green hydrogen vessel deemed ‘highly competitive’ – pv magazine International
https://www.pv-magazine.com/2021/03/02/australian-green-hydrogen-vessel-deemed-highly-competitive/

The “world first” vessel design, which has already been patented, will be able to transport 2,000 tons of compressed hydrogen. GEV, a marine transport company based in Western Australia, says the study confirms that it can deliver the ship itself and a full zero-emissions compressed hydrogen (C-H2) supply chain with minimal barriers. It expects commercialization within the next five years.

...

The C-H2 Ship can carry up to 2,000 tons of hydrogen in its containment system. The company has said that its design “eliminates the requirement for onsite storage, as the C-H2 Ship is itself the storage.” It has described its push to develop a compressed hydrogen ship as a “natural progression to meet a market requirement for the storage and marine transportation of hydrogen.” 

GEV said the scoping study shows that its compressed hydrogen supply chain is economically “very competitive” compared to shipping liquefied hydrogen or ammonia at distances of 2,000 nautical miles (3,700 km). As the company noted, that is roughly the distance between  northern Australia and Singapore. Its C-H2 shipping remains competitive to 4,500 nautical miles, which is the distance from Australia to Japan, South Korea, and China.
