Kütuse element Fuel Cell · Kütuseelement on keemiline vooluallikas, milles saadakse elektrienergiat kütuse oksüdatsioonil vabaneva energia arvel, · on seade, mis suudab toota keemilisest energiast elektrienergiat, ilma et muundaks seda vahepeal mehaaniliseks energiaks. · 2003. aastal allkirjastasid Euroopa Liit ja USA memorandumi nn vesinikuühiskonna rajamiseks, tuginedes veendumusele, et 21. sajandi põhilisteks energiakandjateks kujunevad vesinik ja metaan. Kütuse element Fuel Cell · Esimese kütuseelemendi koostas sir William Growe Inglismaalt juba 1839. aastal. Selles kasutati kahte suhteliselt suurepinnalist plaatinaelektroodi, millest ühel (katoodil) toimus hapniku redutseerumine ja teisel anoodil vesiniku kui kütuse oksüdeerumine. · Ehituse poolest on kütuseelemendi...

1. Hapniku ja Vesiniku füüsikalised omadused Hapnik on värvitu, lõhnata, maitseta õhust raskem gaas. Hapnik on mittemetall, mis on keemiliselt küllaltki aktiivne. Hapnikul on kaks levinud allotroopset vormi: dihapnik ehk lihtsalt hapnik (O2) ja trihapnik ehk osoon(O3). Dihapnik on stabiilne gaas, mis temperatuuril 183° Celsiust kondenseerub siniseks vedelikuks. Ta moodustab mahuliselt umbes 21 % Maa atmosfäärist. Vesinik lihtainena on lõhnatu, värvitu ja maitsetu gaas. Kõige kergem gaas, mis on õhust 14,5 korda kergem. Keemis temperatuur on -253 oC. Ei lahustu hästi vees. Koosneb kaheatoomilisestest molekulidest. Vesiniku molekulide vaheline jõuda on väga nõrk. Kuigi molekulid suudavad kergelt igalt poolt läbi saada. 2. Suurem osa elusorganisme kasutavad hingamisel õhust saadavat hapnikku oma elutegevuses. Õhu hapnikusisaldus (21%) on elutegevuseks optimaalseim. Kui see väheneb 9%-ni, siis tekiva...

Electric car (biological cars) ( , . . , .) One of the most common types of pollution are gases that emit vehicles and to prevent this people asked themselves the goal to take in the use of biologically clean vehicle What is it? Electric car - a car driven by one or more electric motors powered by an autonomous power source (battery, fuel cell, etc.) and not the internal combustion engine. First Electric car Electric car appeared before the internal combustion engine. The first electric car in the form of a truck with an electric motor was established in 1841. Limitations · The large mass of the batteries. · Battery charging time, but there are ways to "quick charge" to the part-time battery capacity. · In most cases, low dynamic performance. · In some hybrids in general there are no electric batteries. · The major auto companies after the 2000s, paid little attention to electric cars ...

Enamlevinumad polümeeride lähtematerjalid · Kõik plastid on polümeerid aga kõik polümeerid pole plastid. Mõned tuntud polümeerid, mis pole plastid on tärklis (ingl k starch), valgud (aminohappe polümeerid), DNA. · The simplified diagram below shows the relationship between monomers and polymers. Identical monomers can combine with each other to form homopolymers, which can be straight or branched chains.

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and perme...

The Cataclysmic Death of Stars Republished from the pages of National Geographic magazine Written by Ron Cowen March 2007 Ever since he was a teenager, Stan Woosley has had a love for chemical elements and a fondness for blowing things up. Growing up in the late 1950s in Texas, "I did everything you could do with potassium nitrate, perchlorate, and permanganate, mixed with a lot of other things," he says. "If you mixed potassium nitrate with sulfur and charcoal, you got gunpowder. If you mixed it with sugar, you got a lot of smoke and a nice pink fire." He tested his explosive concoctions on a Fort Worth golf course: "I screwed the jar down tight and ran like hell." "kaboomWoosley", now an astronomer at the University of California at Santa Cruz, has graduated to bigger explosions--much bigger. Woosley studies some of the most powerful explosions since the birth of the universe: supernovae, the violent deaths of stars. The universe twi...
Sissejuhatus Üle sajandipikkuse elueaga sisepõlemismootor on tänapäeval ajale jalgu jäänud, väheefektiivne ja rohket väävliemissioooni põhjustav seade, töötagu ta siis ükskõik millise kütusega või olgu tal kui tahes efektiivne sissepritse või turbo. Tänane teadus pakub mitmeid uudseid keskkonnasõbralikke, mis on senistest sisepõlemismootoritest suurema kasuteguriga ja keskkonnasõbralikumad. Esimene pool sajandit sisepõlemismootori ajaloost kulus selle täiustamiseks ja arendamiseks, kusjuures selle käigus ei pööratud erilist tähelepanu mitte efektiivsusele ja säästlikkusele, vaid paljuski sellele, kuidas mootorist võimalikult palju hobujõudusid välja pigistada. Alles eelmise sajandi viimasel veerandil hakkasid autotootjad huvi tundma ka materjalide kokkuhoiu ja ökonoomsuse vastu. Kõigil neil on oma vead ja siiani veel lahendamata tehnilised puudused. Ent on selge, et läbimurre ühes või teises suunas on lähiaeg...

EESTI METSANDUS 2011 EESTI METSAD EESSÕNA Eestlastele on läbi aegade olnud omane lähedane suhe metsaga ja pikaajalised head traditsioonid metsanduse arendamisel. Metsad, mille kogupindala on enam kui 2 miljonit hektarit, moodustavad iseloomuliku osa Eesti maastikust, kattes üle poole meie maa territooriumist. Viimase 70 aasta jooksul on metsade puidutagavara suurenenud enam kui 4 korda. Mitmekordselt on suurenenud ka kaitsealuste metsade pindala. See on oluline fakt, millega tuleb arvestada nii metsapoliitika edasisel kujundamisel kui ka metsade kaitse ning majandamise korraldamisel. Käesolev Eesti Metsanduse ülevaade on k...
