Ka ikehu geothermal - he makana mai Mother Earth

Ma ka papa uku o ka ikehu o ka manaʻo kanaka he nui ua lōʻihi Ua hopohopo e pili ana i ka manaʻo o ka finiteness o kumu waiwai ia, i ka maikai a me ka aila kinoea. A e hana oe manaʻo e pili ana i ka hoʻohana 'ana o' ē aʻe, ai '-ʻike mau ikehu kumu. E like me kekahi o kēia mau kumu, e like me nā kānakaʻepekema, ke hana geothermal ikehu.

Ma kona kāna mau 'ōlelo - ia ka ikehu, a i ka hohonu o ke kahua o ka Honua. E like me ka noiʻiʻepekema, aia no he welaʻano piʻina i loko o 20-30 ° C no kēlā me kēia kilomika hohonu i loko o ka honua. Ma ka hohonu o ka 10 km pili i kaʻilikai mahana ke kau he nui loa respectable Hawaiʻi (300 ° C). Eia ka ka mea maloko mahana, a produces geothermal ikehu kumu.

Ma kekahi mau hihia, ka mea hiki ke ike a me ka hana ole i kekahi hou ke kākoʻo 'ana. Pono lawa e hoomanao i ka Valley o Geysers ma Kamchatka, a nui no hoi na wahi ma ka aina o geysers a me ka hoki. Kēia ka ikehu geothermal hiki ole e hoʻohana wale ia e hiki ke pili ia, e pono e kūkulu i e e hiki ke hoʻopio i kēia ikehu kekahi ano o ka mīkini, a e huli ia i loko o hou aku i mea ninau-,ʻo ia ikehu no mākou.

I ka lā, loaʻa nō i nā alaʻelua, hiki e lawe mai i ka hoʻohana 'ana i ka ikehu geothermal:

-neposredstvennoe hoʻohana o ka wela;

-Getting uila.

Eia naʻe, i ka pololei pono o ka wela mea hiki wale nō i loko o kekahi mau wahi, e like me ia ma Iapana a me'Āina Hao. Me ia i kekahi papa hana a me ka wela o ka wai kumu ua hoʻohana 'ia no ka hahana maoli nō kēia a me ka wela poe kuai moni i kaa, pinepine' ana i loko o mines.

E? Ieoaeunoai kuikawa no ka uila geothermal mana mea kanu. Ma keia hihia, ka ikehu geothermal ua hoʻohana 'ia, hoi, ma kekahi mau aoao:

-in ka hihia hele 'ana i ka maloo mahu hua mai mines, e alakai i ka wela wahi hohonu i loko o ka honua. Ma keia wai ua EII ni hohonu mines, malaila ua enaena, a lilo iho la mahu. Ua maloo mahu ua lako i ka mīkini peahi uila kōmi 'ana, i kipaku ka mīkini hana wāwahie armature, ai ka la mahope paha ke he uilaʻikena;

-used hahana loa ka wai, ka mea, ua lako pū ma lalo o puʻe mai ka lalo o ka evaporator, ma ka manaʻo koikoi ikaika emi, ka wai evaporates, a me ka ua loaʻa mahu ua lako i ka mīkini peahi uila kōmi 'ana, i huli mai i ka mīkini hana wāwahie pololei a hiki i ka heleuma;

-used no laila,-kapaia "aeaie" ala. Ma keia hihia, ka ikehu geothermal hoʻomehanaʻana i ka wai. Kēia ka wai i loko o ka wela poe kuai ma ka mea, ua enaena ma ka wela, e loaa hou i kekahi meakino i ka mahana o ka vaporization ma mua o ka wai. Ka mahu lako i ka mīkini peahi uila, a me ka mea kipaku i ka mīkini hana wāwahie armature hoʻomakaʻiaʻikena.

Ma nā mea a pau kēia mau hihia a pau, hiki ke hoʻohana i ka wai i koe ma hope o ka omoāea kaʻina hana no ka la paio hahana maoli nō.

Eia nā 'ano geothermal ikehu hiki ke hoʻohana' ia no ko ka hale ona e pono ai.

It E e kaulana ia i kūkuluʻia ai ka mua geothermal kanu ma Italy hoʻi i loko o 1904, ka mea hana manawa. He nui 'ē aʻe like geothermal mana kanu ma California, ma kahi o 5% o ka uila hoike no ka geothermal mana mea kanu, a me ka mea hana i loko o El Salvador, a ma ka'Āina Hao.

Me ke koe o ka ikehu geothermal mea oiaio inexhaustible a me ka loihi mamua o ka loaʻa me ke koe o mōʻalihaku. No ka geothermal mana kanu drawback mea i ka mea, hiki ke waiho i loko o nā wahi ma kahi e loaʻa nā hoki. Naʻe, ka mea, ua mua, ua ulu a ua hoao ia ma ke koa, i hiki ai e loaa ka ikehu geothermal anywhere.

Ke'ī mai, me ka hāʻawi 'ike e leie aku e noonoo i ka ikehu geothermal kekahi o ka hiki ikehu lako nā koho i loko o ka depletion o ka wāwahie kumu waiwai.
