Nissan Plans Wireless Charging on Electric Cars

It seems we just can’t move these days for news of Nissan’s EV strategy. Well, today’s no exception, with news of Nissan’s plan to develop wireless charging technology to make charging electric cars easier and faster.

The system, based on the principle of inductive charging, employs the same electromagnetic field technology used to charge an electric toothbrush.

Nissan has already adapted the system for use in its Zero Emission Vehicle (ZEV) electric car, which can charge wirelessly in a suitable parking bay, but the latest report suggests that the major Japanese outfit has more expansive plans for its system. The Guardian reports that Nissan hopes to lay a series of plates into the surface of designated electric vehicle lanes on highways, enabling drivers to charge as they travel.

LED lights are more than an energy-efficient lighting alternative— they’re also a potential Wi-Fi replacement technology. Researcher at Boston University are working on Smart Lighting, a wireless technology based on visible light instead of radio frequency.

Apple Looks at Solar to Power Next Generation of Mobile Devices

A couple weeks ago Apple filed a patent to explore the use of solar power in their next generation of mobile devices. With battery life being a long running issue for Apple’s laptops and mobile phones, solar power could help extend use time without having to plug in.

The patent filing discusses placing the solar technology behind the LCD screen of the devices so that the panels would absorb ambient light without adding additional width and bulk to the device. While the technology could be difficult to implement (Motorola filed a similar patent for their mobile devices in 2001 but is yet to be able to successfully integrate solar technology into their devices), having a company as large and influential as Apple roll it out could mean cross product integration with iPods and MacBooks in addition to the iPhone.

The company takes a lot of knocks for not being environmentally conscientious, but downloading tracks and movies instead of buying copies and using maps on mobile instead of printing directions does help limit impact. Making their products more energy efficient is a winning venture for the mega-brand.

Green Mobile: How Cell Phone Makers Stack Up

Having spent a lot of time in the wireless industry and being hopelessly addicted to my Blackberry and my Helio Ocean, I wanted to take a look at how manufacturers and carriers stand up when it comes to enviro-friendly action.

Nokia: Remaking Mobile
Nokia is one of my favorite handset manufacturers. Not only do they have some amazing concept devices, such as the Nokia Remade, a handset made entirely of pre-used parts from old tires to aluminum cans, they also currently have working devices on the market that are reducing impact. With covers made of recycled material and chargers that are Energy Star compliant and then some, Nokia is making bold strides in the right direction.

The 3110 Evolve’s biocover is made with 50% renewable material, and the packaging has been reduced by 60% for the handset. Along the a charger that uses 94% less energy that Energy Star compliance requires.
