Each day that passes are more convinced that non-conventional renewable energy (NCRE) or alternatives are a real option to industry and individual level to provide electricity not only sustainable but autonomous and, looking to the long term, cheaper. Was that one of the central themes of the seminar solutions with renewable energies not conventional who organized the Regional Government of Aysen, the University of Chile and the National Commission of energy altogether, and which met for two days in the Auditorium of the Regional Library to specialists in the field of solar energy, mini hydraulics, windgeothermal, and biomass. In what I showed it was more or less clear that the potential across the country, beyond some discussion about the figures, shows that we are a nation rich in renewable energy. And that will vary from region to region, depending on the most cost-effective energy in each zone. In the North is the Sun, and here in Coyhaique biomass, wind and hydro-electric micro power have potential Giants explained the doctor in engineering from the University of Dortmund, Rodrigo Palma, on the energy wealth of Chile. With respect to costs, he noted that these technologies tend to be more expensive than large scale solutions, but have many advantages in environmental matters, image and local development in terms of work. And the numbers are very clear. The expert delivered data for the potential contribution of non-conventional renewable energy and energy efficiency study to the electrical grid, 2008-2025 of the universities of Chile and Federico Santa Maria, which notes that in the area mini hydraulic Chile has potential to generate 20 thousand MW, in geothermal 16 thousand, in wind power 40 thousand, in biomass almost 14 thousand and 100 thousand solar, in total, 190 thousand MW. This volume, in the Central interconnected system today installed capacity is only 330 MW. For this reason, in his opinion, one of the great challenges should be flirting discussion of energy development with the discussion on the possibilities of technological and industrial development at national level in the topic energy.

The Wi-Fi, often called Wi-Fi modems, routers are electronic devices that allow Internet access through a wireless access point Wi-Fi to the machines on a wireless local area network WLAN (Wireless LAN, wireless local area network). All telephone networks, whether fixed, mobile, cable or radio, have Wi-Fi routers to connect to the Internet and share the connection transparently with other computers that have Wi-Fi connectivity. Features Wi-Fi routers and Wi-Fi modems expressions are generic terms that are used interchangeably to refer to those teams that allow access to the Internet to a local network wireless Wi-Fi. Let’s look at some important features: configuration: normally the Wi-Fi routers are configured through web interface. An accessible web page on the 192.168.1.1 IP allows setting all the options of the computer. Security: implement security on the Wi-Fi routers is important mainly for two reasons: protecting the use of bandwidth by strangers and prevent access intrusion to the local network machines. There are several systems to protect the access, being the most common set a WEP password or enable filtering by MAC, although all the security methods can be violated by persons with sufficient knowledge. Features: Wi-Fi routers are devices that perform several duties at the same time, since they act as a gateway, router, modem, switch and wireless access point.

Additional functions: often have network advanced features such as DHCP server, firewall, DNS server, filtering of packages or encryption. Storage unit: some models incorporate features that allows it to be used as a unit of shared storage accessible from any computer on the network, as I drive hard internal, USB port for connecting external hard drives or FTP file server. Types look at the main types of Wi-Fi, according to the type of telephone network routers give you access: fixed telephone network: to access the Internet through a telephone line fixed ADSL Wi-Fi ADSL routers are used. Mobile network: to connect to the Internet through a cellular network (GPRS, UMTS, HSPA, EVDO, WiMax, 3 G) have two options, the Wi-Fi 3 G routers, an external modem that has Wi-Fi connectivity, and the 3 G USB modem equipped with a basis Wi-Fi that implements the functionality of the WLAN router. In both cases requires a SIM card to identify itself to the telephone operator. Another possibility for mobile Internet access is to leverage the many mobile phones to serve as a Wi-Fi routers for other teams, being indispensable requirement for this that both have Wi-Fi connectivity. Telephone cable network: some Wi-Fi routers called modem are used to access the Internet through an infrastructure of television by cable. Telephone radio network: WiMAX router are used to get Internet connection over a telephone network by radio.
