Linde Group Created a Hydrogen Bike


Use the hydrogen (H2) to power vehicles is not a new idea, but it is the first time it os applied in a bike. The H2 has been introduced as an alternative to a commom electrical motor. The battery is replaced with a compact fuel cell and generates its own electricity using a 34-gram cylinder of hydrogen and oxygen it takes from the surrounding air. Currently, this hydrogen fuel cell offers a range of over 100 km.

Estimated Time of Discharge and Charging a Battery

A simple but useful calculation is the estimated time of discharge and charging a battery. So, first you need to know the battery capacity that is expressed in Ah. The time of discharge is given by de expression Capacity (Ah)/Consumer Load (A).

DL 153/2014 - Regime de Produção de Electricidade para Autoconsumo

Foi adicionada à Biblioteca de Downloads o DL 153/2014 que regula a produção de energia eléctrica em auto-consumo. Num contexto ambiental cada vez mais exigente a produção descentralizada para auto-consumo a partir de energias renováveis como a energia solar é um passo significativo para a redução de emissões CO2, "alívio" da rede eléctrica e infra-estruturas, assim como na redução da factura eléctrica doméstica. Ao tema pretendemos voltar em mais artigos.

Quadraplegic Drives a IndyCar

Schmidt has been paralyzed in 2000 in a car accident. He unable to use his arms or leggs, he can not accelerate or brake, even move the steering wheel, but recently he can drives in a modified car in Sonama Grand Prix road cours. He as part of Arrow Electronics Semi-Autonomous Motorcar (SAM) project, the high-speed demonstration showcased their recently-developed integrated semi-autonomous driving technology.

Robotic Glove



A new robotic glove help users take a control of their hands. Litle daily tasks can be a big obstacle for patients with spinal cord injuries. That new robotic glove developed by engineers could change that.

John A. Paulson it is the developer, he is researcher in the Engineer School of Harvard University. Paulson gave much importance to usability and user comfort so he and his team it is engaged so that it seemed as natural as possible. The actuator system has made with kevlar and silicone elastomer. The glove is extremely lightweight.
