NULL The electric and super-compact design car

The electric and super-compact design car of the future, beautiful and futuristic design by Jeongche Yoon. This is the Null, a mobile widget concept for next generation EV (Electric Vehicle) has been designed as solution to save energy and space. Inspired by smart phone industry based on the open-source marketing of app store, this is more like hardware that you put on your car to make it do more.

This is exciting new opportunities for automobile industry to establish a clean and creative design for the future society.

Charge Control

Charge Control is a technology that lets an electric utility control, in real time, the charging of a gridable (plug-in) vehicle, such as a Plug-in hybrid (PHEV) or a Battery electric vehicle (BEV). Through Charge Control, the utility is able to postpone charging of the vehicle during time of peak demand. Additionally, this technology may enable the owner and the power company to track the vehicle's usage and performance, while on the road and while charging.

* During times of peak demand, the electric utility prefers to reduce the demand, rather than turning on additional (dirtier and more expensive) power plants. In places that subscribe to Smart Power Grid services, the electric utility shuts off appliances such as air conditioners until the peak demand is over. Similarly, Charge Control allows the electric utility to postpone charging until the peak demand is over. Charge Control is not as far reaching as V2G (a technology that allows the power company to buy energy back from a plug-in car) but is very effective because it is less expensive to implement than V2G.

* The hardware used in Charge Control also monitors the vehicle (when driving or when plugged-in). As a side benefit, that information is available, through the web, to both the electric utility and the owner, for the purpose of tracking and optimizing the performance of the vehicle.

* Eventually, the electric utility may offer better pricing to owners of Charge Control equipped vehicles.

n both V2G and Charge Control, the electric utility can control the power flow between a plug-in vehicle and the power grid. However, in Charge Control power only flows from the grid to the vehicle, while in V2G power can flow in both directions.

Bonded DSL Rings

Bonded DSL Rings (BDR) is a technology lets rural and urban telcos move voice, video & data traffic over their existing copper telephone lines at speeds of up to 400 Mbit/s. Installation costs for BDR are less than 1/20th of optical fiber. A proof of concept of BDR was displayed at the Broadband World Forum in Berlin, Germany in October 2007 and at the MINT Lab in Edmonton, Canada in November 2007 by Genesis Technical Systems Corp. The patent for Bonded DSL Rings is still pending.

BDR works by combining existing telecom standards, and uses existing copper pairs. BDR combines the capabilities of VDSL2, DSL Bonding (using G.Bond), Resilient Packet Rings (RPR) technologies and add-drop multiplexers (ADM) in a collector ring instead of the historic tree and branch approach.

VDSL2 increases the bandwidth of existing copper lines, but can result in poor performance due to cross talk. BDR has resolved these distance sensitivity and cross talk problems.

Fiber and wireless based alternatives for telcos may involve no longer utilizing existing copper telephone lines, unlike BDR.
