Energy Internet and eVehicles Overview

Governments around the world are wrestling with the challenge of how to prepare society for inevitable climate change. To date most people have been focused on how to reduce Green House Gas emissions, but now there is growing recognition that regardless of what we do to mitigate against climate change the planet is going to be significantly warmer in the coming years with all the attendant problems of more frequent droughts, flooding, sever storms, etc. As such we need to invest in solutions that provide a more robust and resilient infrastructure to withstand this environmental onslaught especially for our electrical and telecommunications systems.

Linking renewable energy with high speed Internet using fiber to the home combined with eVehicles and dynamic charging where vehicle's batteries are charged as it travels along the road, may provide for a whole new "energy Internet" infrastructure for linking small distributed renewable energy sources to users that is far more robust and resilient to survive climate change than today's centralized command and control infrastructure.

Wind powered cell phone tower

[Here is a good example of the type of innovation we need for future wireless and wired networks. Although the emission of CO2 by telecommunication networks is relatively small, the rate of growth of these emissions is much faster than from other sectors of society. This is one example of a larger research strategy, of which Ericsson is a partner, to power all components of the network with renewable power including distributed computing, optical repeaters, switches, Internet routers and CPE equipment. This will create new challenges in terms of reliability and restorability of the network. Stay tuned for some major announcements in this field next week at the PROMPT workshop and the California Canada summit on Green IT – BSA]

Ericsson Designs a Wind-Powered Cell Tower
Working with Vertical Wind AB and Uppsala University in Sweden, Ericsson researchers have developed a wind-powered tower for wireless base stations.

The wind-powered Tower Tube takes the energy-lean design of Ericsson's original Tower Tube one step further by employing renewable energy. It harnesses wind power via a four-blade turbine with five-meter blades vertically attached to the tower. The vertical rotor blades work silently and minimize the load on the tower during operation.

Trials are currently planned to determine if the design can truly enable low-cost mobile communication, with reduced impacts on both the local and global environment.

The Ericsson Tower Tube construction houses base stations and antennas, fully enclosing them in an aesthetically pleasing concrete tower. It has a smaller footprint and lower environmental impact than traditional steel towers with CO2 emissions related to materials, such as production an transportation, that are at least 30 percent lower.

Furthermore, the Ericsson Tower Tube has no need for feeders and cooling systems. With up to 40 percent lower power consumption than traditional base station sites, it helps operators reduce their operating costs significantly. It employs cutting-edge design and can be built in many sizes and painted in a variety of colors, making it a natural fit for any landscape.
