Télen is fűt a méhsejtes napkollektor

Télen is fűt a méhsejtes napkollektor

Hidegebb éghajlaton és korlátozott napfény esetén is jó teljesítménnyel készít használati meleg vizet az az izraeli fejlesztésű méhsejtes napkollektor, amely bekerülhet az év legjobb megújulóenergia-innovációi közé. A használati meleg víz készítésre ma jellemzően síkkollektort vagy vákuumcsöves kollektort alkalmaz, aki a napenergiát hasznosítja. A Tigi izraeli cég által fejlesztett napkollektor a méhsejt szerkezetéhez hasonlító áttetsző szigetelőréteggel rendelkezik, amelynek köszönhetően ötször több energiát lehet vele előállítani, mint egy síkkollektorral. Az élettartama pedig kétszerese a fejlettebbnek tartott vákuumcsöves készüléknek, nagyjából 20 … Teljes cikk »

Haifa Christmas Tree Made From Over 5,000 Recycled Plastic Bottles

Haifa Christmas Tree Made From Over 5,000 Recycled Plastic Bottles

  The city of Haifa, in northern Israel, has Jewish, Christian, Baha’i and Muslim residents, and so many religious holidays are celebrated there.  In honor of the upcoming Christmas holiday, the Haifa Municipality approached local artist Hadas Itzcovitch about creating a Christmas tree for the city.  Unfortunately (and perhaps symbolically) the tree went up the day the catastrophic Carmel fires began in the region.  And so as 5000 hectares of natural trees were burning in the area, … Teljes cikk »

Áramot termel az autópálya

Áramot termel az autópálya

A járművek tömegüknél és mozgási energiájuknál fogva folyamatosan hatást gyakorolnak az úttest burkolatára. Ez a hatás elsősorban nyomás és vibráció. Az ilyen formában elnyelődő energia veszendőbe megy. Az izraeli Innowattech cég kutatóinak eljárásával azonban jelentős része árammá alakítható. Az Állami Autópálya Kezelő Zrt. kísérleti jelleggel már idén telepíteni szeretné egy hazai autópálya-szakaszon a rendszert. A ra’ananai székhelyű Innowattech alternatív energiatermelő rendszerének lelkét a cég által kifejlesztett piezoelektromos generátorok új generációja alkotja (Innowattech Piezo Elektric Generator – … Teljes cikk »
