Engxenyeni engaphansi yamadolobha kukhona amandla athile okukwazi ukukhiqiza amandla ngemithombo evuselelekayo. Isibonelo, sebenzisa ngokunenzuzo i- imisinga yomoya emihubheni ehamba ngaphansi kungaba kuhle ekukhiqizeni amandla omoya. Ngakolunye uhlangothi, ugesi ungadalwa yizinyawo zabahamba ngezinyawo.
Ukukhulisa ukusebenza kahle kwamandla nokusebenzisa amandla avela ngaphansi komhlaba emadolobheni nakwezinye izindawo, kuye kwathunyelwa imibono eminingana ngesikhathi se- Mina I-Madrid Subterra International Congress.
UFrancisco Bugarín, umphathi omkhulu wenkampani Amandla eTunel, wethule engqungqutheleni ugesi ophendulwa entanyeni yesandla futhi ngasikhathi sinye uvumela ukukhiqiza amandla omoya ngemisinga yomoya ebangelwe ukudlula kwamamitha. Isebenza futhi nakwezinye izindawo lapho kukhona okusalungiswa, njengamaphaseji esikole noma efemini.
Imisinga yomoya ebangelwe ukudlula kwamamitha yaziwa njenge "Umphumela wepiston”. Ngale misinga engaba amakhilomitha ayisithupha ngehora, i-turbine yomoya ingakhiqiza i-watt eyodwa yamandla. Lawa ma-wind turbines angafakwa kojantshi be-modular futhi akwazi ukufeza inhlanganisela evumela ukuthola amandla adingekayo ngokufakwa. Ngama-turbine amathathu lawa omoya, kungakhanyiswa isibani esinama-watt amathathu.
Uma ubheka lokhu, izakhiwo zinganwetshwa noma zinciphiswe ngokuya ngezidingo zamandla kagesi, kusizakale iqiniso lokuthi umhlangano uyashesha futhi ukugcinwa kwawo kulula. Kungathatha cishe amahora amathathu ukuguqula ukufakwa, ngakho-ke ngeke kuphazamise insiza.
"Kuyiphrojekthi eguquguqukayo kakhulu ngoba ingakhiwa kunoma iyiphi indawo noma indawo, ngakho-ke ukusetshenziswa kwayo akugcini kuphela kudolobhana kepha ingasetshenziswa ku- ezinye izindawo”Kusho uBugarín.
