The SiGNa Powertrekk Energy Efficient

The Consumer Electronics Show (CES) wrapped up Jan. 13, after a typically splashy convention that unveiled numerous new gadgets. Although some of the items are perhaps less useful than others – automated unicycle, anyone? – many of the consumer electronics displayed are notable for their practical embrace of energy efficiency measures. To insiders, this signals that manufacturers are cementing energy efficiency as a part of their business models going forward.

Here are some of the more notable energy-efficient innovations from CES:

SiGNa Powertrekk

The Signa Powertrekk (picture above) is a new spin on batteries: Just add water. Meant to power devices on the go, the Powertrekk works by combining sodium metal and silicon powder in round “PowerPucks.” The pucks are safe and inert until a user adds water, which causes a chemical reaction that produces hydrogen. Consumers can power mobile devices and other items by connecting them to the Powertrekk with a USB cord. Another byproduct is sodium silicate, a naturally occurring chemical that can be found in toothpaste. The device will be aimed initially at campers and sportsmen, but the company has been recognized by USAID and the Pentagon for the many possibilities this type of portable generation offers.

Lighting Science Group Lighting Science World Bulb

The World Bulb is an "omnidirectional" LED that is designed to handle the uneven quality of power systems in emerging economies. The bulb's brightness is equivalent to a 60-watt incandescent, but only uses 9 watts – which is 35% less power than CFLs. It is designed to sell for less than $15. The World Bulb's payback versus an incandescent is eight months, with a calculated lifetime of 17 years.

2D2C, Inc. SafePlug Electrical Receptacles

Integrated home systems are the next big step in energy efficiency. The SafePlug receptacle is designed to reduce energy consumption by up to 30% by responding to utility a company’s demand response controls. When energy is expensive, houses that participate in these programs will receive messages from utilities that will power down appliances that use the most energy, which will save the homeowner money and energy.

Nest: Nest Learning Thermostat

Probably the most talked about thermostat in years. Nest can sense when you are home and takes the weather into account, adjusting itself to keep your house comfortable and reduce your energy bill. A consumer can also control Nest from smartphones and computers, at home or away.

Samsung WF457 Front-loading Washer 

Smart grid-ready, the Samsung WF457 washer uses 70% less water than a top-loading washer. It also has the capacity to launder 31 towels. It can also be controlled via smartphones – so users who monitor their energy can start their laundry when energy costs the least. Check out the bright display! This new generation of smart washing machines combined with cold-water washing can save energy and money.

Eastern Asia Technology Limited USB Power Socket 

This socket fits into a normal wall socket, creating two USB charge ports. A built-in sensor completely cuts off power when a device is fully charged to avoid using unnecessary standby "vampire" power.
