Ma ke ʻano he mea multifunctional hou, hoʻokumu nui ʻia ka pahu keleawe ma ke keleawe, a ʻo ka nui o nā lua i hoʻopili ʻia a i ʻole i hoʻopili ʻia e hoʻohele like ʻia, pēlā e hana ai i nā mea multifunctional hou e like me ke keleawe keleawe.
ʻO ka pahu keleawe he kani a me ka demagnetizing, ʻaʻohe mea ʻawaʻawa a ʻaʻole pōʻino.

Loaʻa i ka hapa nui o nā metala puʻupuʻu maikaʻi nā waiwai insulation leo a hiki ke pale i nā hōʻailona electromagnetic. Loaʻa iā Copper foam kēia pono, no ka mea, ʻo ke kani ma luna o ka ʻili o ka ʻūhā keleawe, ʻaʻole wale e hiki mai ka noʻonoʻo diffuse; ma o ka hoʻonui ʻia ʻana o ke kani ʻana. ʻO ke kumu micro-porous anechoic, hoʻokō maoli i ka hopena o ke kani anechoic. I ka manawa like, hiki i ka pahu keleawe ke pale i nā hōʻailona electromagnetic, a hoʻohana pinepine ʻia e like me nā mea pale electromagnetic. ʻO ka pahu keleawe ponoʻī ʻaʻole ia he mea ʻawaʻawa a maikaʻi ʻole i ke kino o ke kanaka, me ka nui o nā pores o loko; hoʻohana ʻia ʻo ia ma ke ʻano he mea kānana olakino e nā mea hana hoʻomaʻemaʻe wai.
ʻOi aku ka maikaʻi o ka hoʻoili uila ʻana o ka huʻa keleawe no ka mea ʻoi aku ka liʻiliʻi o ke kumu kūʻai ma mua o ka nickel foam; no laila, ua hoʻohana nui ʻia ia ma ke ʻano he electrode backbone material i nā pila hou. Hoʻohana ʻia ʻo Copper foam ma ke ʻano he catalyst e hoʻomaʻamaʻa i nā hopena kemika i kekahi mau hopena kemika ma muli o kona ʻāpana kikoʻī nui. I kēia manawa, ʻoi aku ka ikaika o ka hoʻoheheʻe keleawe a me ka retardancy lapalapa maikaʻi loa; hoʻohana maʻamau ia i ka hana ʻana i nā mea thermally conductive a hoʻohana nui ʻia i nā kaʻa uila a me nā mea hoʻoheheʻe wela uila.
