based in https://www.technologyreview.com

In recent years, business talk is talk of entrepreneurial start-ups. US companies based in Silicon Valley that received venture capital doubled between 2007 and 2012. Silicon Valley is a nest of digital technology companies that develop an astonishing variety of products and services.

This reality of supporting at new enterprises hides a less exciting reality. A group of researchers dedicated to the study of this issue in the United States. This group concluded that the number of companies with less than one year fell by 50% between 1978 and 2011, with the sharpest decline was in recent years. The number of workers assigned to these companies also decreases dramatically.

Google in Textile Industry

based in https://www.technologyreview.com

Incrasingly Google is surprising by innovation and to built pertinent gadget's but at the same time incrasingly our doubts about how much they dominate our life and invade our privacy. In last year Google enters in the textile industry.

The Project Jacquard is creating textiles woven with grids of conductive yarns that are made with typical manufacturing. Google aspires make smart clothing, furniture and toys and their concern is not only usability but also the durability. They imagine control gadgets with fingers gestures in the clothing. Levi Strauss is also working with Google on this project and they announced that working to integrate touch panels into its clothing.

Microsoft Acess in Engineering - Textile plannig Case

The Microsoft Acess it's a very powerful tool include engineering. This toll is much often forgotten over Excel for example but in reality it is much more powerfull. This platform combines a good database with a great graphical environment for creating forms with objects and methods preconfigured and easy to adapt. Handling the database it's also facilitated, for this task also have a graphical environment to create SQL instructions. 

Car 2 Car Communication

Definitely the communication technology reached the car. Car 2 Car Communication Consortium (C2C CC) is a organisation initiated by European vehicle industry and supported by equipment supplier.

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.

Free Simulator to Arduino

The  site https://123d.circuits.io offer a free simulator to electronic circuits with arduino. It's easy and simply to use.

It is not our intention explain how to use this, but we post a first video that demonstrate the basic features.

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.
