O miriense Gercinaldo Fonseca acaba de comercializar uma
invenção que deve apresentar uma solução para construção naval de rabetas (para
motores rabudos) sem a necessidade do desmatamento.
Esse tipo de veículo que atualmente é o principal meio de transporte ribeirinho
(substituindo até mesmo as canoas tradicionais) traz enormes conseqüência
ambientais para a natureza já que é construído a partir do derrubamento de
árvores.
A minimização do problema do desmatamento pode estar na nova matéria prima para
a construção das rabetas, conforme propõe o torneiro mecânico Gercinaldo
Fonseca, morador do bairro da Cidade Nova, Igarapé-Miri, que utilizando os
conhecimentos em metalurgia construiu um primeiro modelo desse tipo de rabeta
utilizando o alumínio naval.


Gercinaldo enumera diversas vantagens da nova rabeta como por exemplo:
• Não precisa gastar material com calafeto
• O tempo de duração é muito maior
• E o que é melhor não precisa desmatar





O miriense também já está desenvolvendo uma acessório chamado
"olho que tubarão " que segundo ele vai minimizar o acidentes de
rabetas, tão comum atualmente.
Quando perguntamos sobre a viabilidade de custo, Gercinaldo diz que o primeiro
modelo foi comercializado pelo valor de R$ 3.500,00, mas garante que é
vantajoso, já que uma rabeta do mesmo tamanho custa em média R$ 2.000,00 com
tempo de duração de 6 meses a um ano, a rabeta de alumínio tem tempo de duração
indeterminado, ainda assim ele acredita que é possível que com a produção em
grande escala garanta o barateamento do produto.
Gercinaldo concluiu dizendo que durante muito tempo fez observações no intuito
de compreender a realidade local, o que lhe somou ideias para a confecção desse
tipo de rabeta, disse ainda que está muito confiante nos resultados do
positivos proporcionados pelo seu invento.
