Biocombustível portátil

microfueler-100-0805-00.jpg

Viajando pela Net, deparei-me com esta notícia verdadeiramente curiosa e de grande ajuda para os dias que correm. Trata-se de uma máquina que produz bioethanol, a partir de restos de bebidas alcoólicas ou açúcar, com o preço por litro de combustível a rondar os 0,60 €.

A máquina, denominada E-Fuel 100 MicroFueler, pesa 90 kg e custa uns 7 mil euros. Certamente estará a fazer contas de quanta gasolina poderia comprar com 7 mil mocas, muita… mas cada vez menos, se dependermos dos preços das gasolineiras. O tamanho da E-Fuel é semelhante ao de uma máquina de lavar roupa, e o desenho é de Floyd Butterfield, cientista que no ano de 1982, ganhou um concurso com esta ideia.

Obtém-se bioethanol a partir de açúcar, uma levedura especial, água e corrente eléctrica (220 V). Segundo os seus criadores, criar o combustível é uma tarefa bastante simples, basta abrir a porta, deitar açúcar para dentro e apertar o botão.

O processo necessita de 7 dias para obter 130 litros de álcool, consumindo 15 litros de água e 4,5 a 6,35 kg de açúcar mascavo.

Os vídeos seguintes revelam um pouco mais do processo.
