El dimecres i el dijous de la setmana passada vam fer un taller d\u2019energies renovables no contaminants. Consistia en utilitzar 4 maquetes que funcionaven amb les seg\u00fcents energies:<\/span><\/span><\/span><\/p>\n

– solar t\u00e8rmica (aprofita l\u2019escalfor del Sol)<\/span><\/span><\/span><\/p>\n

– solar fotovoltaica (aprofita la llum del Sol)<\/span><\/span><\/span><\/p>\n

– hidr\u00e0ulica (aprofita l\u2019aigua)<\/span><\/span><\/span><\/p>\n

– e\u00f2lica (aprofita el vent).<\/span><\/span><\/span><\/p>\n

De cada maqueta hav\u00edem d\u2019identificar les seves parts, <\/span>explicar com funcionava, on la situar\u00edem i els avantatges i inconvenients.<\/span><\/span><\/span><\/p>\n

Sobre la solar t\u00e8rmica<\/u> vam aprendre que pod\u00edem escalfar l\u2019aigua aprofitant la calor dels <\/b>raigs del Sol<\/b>; a trav\u00e9s del serpent\u00ed. El serpent\u00ed \u00e9s un tub negre (per absorbir m\u00e9s l\u2019escalfor del Sol) que fa circular aigua. Tamb\u00e9 t\u00e9 un mirall que \u00e9s perqu\u00e8 la llum del Sol reflecteixi i encara hi hagi m\u00e9s calor.<\/span><\/span><\/span>
\n\"\"<\/a>
\nNosaltres hem apr\u00e9s que les plaques<\/u> fotovoltai<\/u>ques<\/u> funcionen gr\u00e0cies a la llum del Sol<\/b>. Aquesta llum, gr\u00e0cies a les plaques solars, podem transformar-la en electricitat.<\/span><\/span><\/span><\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Amb l\u2019energia hidr\u00e0ulica<\/u> es fa funcionar una turbina que ha d\u2019estar en un lloc on hi passi aigua molt r\u00e0pid (salts d\u2019aigua, cascades, rius, pantans…). L\u2019aigua cau a les culleres i fa que la turbina giri. L\u2019energia que passa pel transformador es converteix en electricitat.<\/span><\/span><\/span><\/p>\n

\"\"<\/a><\/p>\n

 <\/p>\n

Per obtenir energia e\u00f2lica<\/u> es necessiten molins situats a les muntanyes on faci vent. El transformador transforma el moviment de les aspes en electricitat. Per\u00f2 no tot s\u00f3n avantatges, un dels inconvenients \u00e9s que si no fa gaire vent, no giren les aspes i no obtenim electricitat. A m\u00e9s, pels ocells, \u00e9s un perill ja que poden topar-hi i en ocasions hi ha menys arbres per haver-los hagut de talar per construir els molins.<\/span><\/span><\/span><\/p>\n

\"\"<\/a><\/p>\n

El taller ens ha servit per saber els tipus d\u2019energies renovables i quines utilitats tenen. Esperem que hagueu apr\u00e9s com funcionen i que no nom\u00e9s hi ha combustibles f\u00f2ssils com el petroli o el gas natural per aconseguir electricitat.<\/span><\/span><\/span><\/p>\n
