Nyanja ili ndi zinthu zosiyanasiyana zomwe zimatha kupanga mphamvu

Pakati pa mitundu yosiyanasiyana ya mphamvu zosinthika, zomwe zimayambira kunyanja ndizofunikira kwambiri. Mawuwa amachokera poti popeza kulibe "mithunzi" m'nyanja, zida monga mpweya, zitha kugwiritsidwa ntchito mokwanira. Mwanjira ina, palibe zopinga ndipo mpweya ukhoza kugwiritsidwa ntchito bwino ngati makina amagetsi amphepo, omwe ndi masamba awo akulu amatenga mphepo pang'onopang'ono ndikusintha kukhala mphamvu zochulukirapo.

Mphepo yakunyanja

Mosakayikira, mphepo yakunyanja yakhala ikubwerera mobwerezabwereza yamtundu wake, kumapeto kwa 2009 idakhala ndi mphamvu ya 2 zikwi 63 Mw ndipo ngakhale kuli atsogoleri mderalo monga Denmark ndi United Kingdom, mayiko monga China ali akudzipereka kuwonjezera mphamvu zawo, ndikupanga kafukufuku wambiri, chitukuko ndi ukadaulo waluso womwe umalola kuponderezedwa kwakukulu kwa minda yamphepo yakunyanja pakupanga Makina amphepo omwe amatha kugwira bwino ntchito kuchokera kunyanja.

Mphamvu yamafunde

Koma munyanja ndiye gwero lazinthu zingapo, motero mphamvu zopangidwa ndi mafunde (mphamvu yoweyula galimoto) amathanso kusandulika kukhala magetsi.

Ngakhale sichinapangidwe bwino, ili ndi matekinoloje oyesera:

- Makina ozikika pagombe kapena kunyanja (m'badwo woyamba).

- Zinyumba zakunyanja zokhala ndi zinthu zoyandama kapena pansi pamadzi (m'badwo wachiwiri).

- Zinyumba zakunyanja, m'madzi akuya okhala ndi malire a 100 mita, okhala ndi zoyandama kapena zonyamula (m'badwo wachitatu)

- M'dziko la Basque pulojekiti ikupangidwa ndi ukadaulo wotchedwa Kukokomeza Danga Lamadzi momwe kuyenda kwa mafunde kumapangitsa kupanikizika kwa mpweya womwe uli m'mbali yolowezedwa pang'ono, wokhala ndi mphamvu yokwanira kuti mphepoyo itheke ndikugwiritsa ntchito chopangira mphamvu.

- Zida zina zili zoyamwa kapena zotsekemera, yomwe imagwiritsa ntchito kayendedwe ka mafunde kuti apange magetsi omwe amasinthidwa kukhala magetsi.

- Matekinoloje ena amatengera machitidwe osefukira ndi omaliza.

Mphamvu yamafunde

Ndizokhudza kupindula ndikukula kwa nyanja komwe mafunde amatulutsa. Mfundo ndiyakuti dziwe lamadzi limadzazidwa ndi mafunde akulu ndikutsanulidwa pamafunde otsika, pomwe madzi pakati pa nyanja ndi dziwe amafika pamlingo winawake, madzi amadutsa mu turbine yomwe imatulutsa mphamvu yamagetsi. Ku France (La Rance) kuli malo otere.

Njirayi ili ndi zovuta zake: kutalika kwa mafunde kuyenera kupitilira mamitala 5, zomwe ndi malire chifukwa izi zimakwaniritsidwa m'malo ena okha. Chosavuta chachiwiri ndi chake kukhudzidwa kwachilengedwe Kutalika chifukwa izi zimachitika m'malo ofunikira Zamoyo zam'madzi.

Kuwotcha kwanyanja

Ndi kusiyana kwa kutentha pakati pa nyanja ndi madzi akuya, omwe kutentha kwake kumakhala kwakukulu kuposa 20º C (madera a equatorial ndi subtropical).

Ndiukadaulo womwe ukuyamba kumene m'maiko ngati India, Japan ndi Hawaii.

Kuthamanga kwa Osmotic

Limatanthawuza kugwiritsidwa ntchito kwa kusiyana kwa kuthamanga pakati pa madzi abwino ochokera mumitsinje ndi madzi amchere ochokera kunyanja. Kampani yakunyumba yaku Norway Statkraft ikupanga projekiti ku Oslo fjord yokhala ndi mfundozi.

Kuyika mchere

Zimachokera ku kusiyana pakati pa mchere pakati pa madzi amtsinje ndi madzi am'nyanja. Pamene madzi awa asakanikirana, amapanga mphamvu zomwe zimatha kusandulika kukhala magetsi.

Nyanja imapereka mphamvu zambiri koma matekinoloje omwe angawagwiritse ntchito akadali mgulu loyesera, kupatula mphepo yakunyanja, yomwe ili yopikisana kale.

Chovuta chachikulu ku mphamvu zam'madzi ndiye mtengo wapamwamba wogwiritsa ntchito, izi zachepetsa chitukuko chake poyerekeza ndi zina mphamvu zosinthika.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
