Comments Off on Houston Getting Extensive EV Charging Network

NRG Energy, a New Jersey-based utility company is building the nation’s first privately-funded network of electric vehicle charging stations in Houston.  EV drivers can subscribe to the service, giving them access to both private, home-based and public charging stations around the city The network is called evGo and will put everyone in Houston within five miles of a charging station by the end of 2011. There will be two levels of subscriptions.  For $49 a month customers will be provided with their own private charging station.  For $89 a month, customers will have access to a network of 50 to 150 charging stations located in public parking lots across the city,   The stations will mainly be in retail locations like Best Buy and Walgreens.  The network will include quick-chargers that can fully charge a battery in 25 minutes. If the the $10-million charging network is successful in Houston, the company plans to expand the idea to other major cities, with New York and Dallas at the top of the list.  NRG plans to focus on states where the electricity industry is deregulated, like Texas.

Comments Off on Using Bacteria to Heal Cracked Concrete

University of Newcastle building scientists have developed a means of repairing damaged or deteriorated concrete using a genetically engineered strain of a common soil bacteria. Nicknamed ” BacillaFilla ,” the bacteria have been modified so that they migrate into the deepest parts of cracks where they then begin to produce calcium carbonate. Calcium carbonate binds with concrete and can repair small fractures and restore broken concrete to its original strength.
