Neajunsul consumarii tocmai cand iti e lumea mai draga a bateriilor care asigura functionarea laptopurilor (computerelor mobile) va lua in curand sfarsit. Gigantica firma electronica nipona NEC a prezentat prototipul unui computer mobil avand incorporata o pila sau baterie de combustibil (fuel cell), care poate prelungi considerabil durata de functionare autonoma a modelelor cu ajutorul bateriilor obisnuite. Prototipul poate asigura o autonomie de functionare de cinci ore, dar versiunile perfectionate, proiectate a fi puse la punct in urmatorii doi ani, vor putea functiona neintrerupt timp de 40 de ore sau chiar mai mult. Pila de combustibil utilizeaza o cantitate redusa de metanol (300 centimetri cubi), care, cu ajutorul unui catalizator, produce, prin descompunere, curent electric. Ea cantareste 0,9 kg, dar, impreuna cu sistemul de incorporare in laptop, greutatea se ridica la 2 kilograme. Primele computere mobile prevazute cu pila de combustibil vor fi puse in vanzare in 2004, iar pana in 2006 se vor gasi pe piata si modele perfectionate, cu o durata de functionare de 40 de ore. Este interesant ca ideea unor pile de combustibil incorporate este luata in studiu si pentru telefoanele mobile, evident, dimensiunea acestor pile fiind si mai mica. Motorola este una din companiile implicate in acest proiect.
