Along with the ever-persistent problem of range anxiety, one of the things that keeps many people from taking electric cars seriously is the limited number of charging stations. What happens if your destination doesn't have one, or if you have to park your car out on the street when you're at home? In the case of some electric scooters and bicycles, users can remove the vehicle's battery and take it with them to charge indoors. Now, Italian automaker Estrima is offering that same feature in its Birò electric car. Read More

True or false: solar and wind power are freely available and clean, and thus should always be stored when they generate more energy than the grid can use? It's easy to assume that renewable energy should never be turned off, but scientists at Stanford have done the math to find the break-even point where storing energy is better than "wasting," or curtailing, that energy, and their findings aren't necessarily as you'd think.

Ambient backscatter tech allows devices to communicate, sans batteries

By - August 14, 2013
In order for the Internet of Things to become a reality, devices will need to be able to communicate with the internet and with one another. If they have to be powered up in order to so, however, a lot of electricity is going to be wasted. That’s where a new technology known as “ambient backscatter” comes into the picture. Developed by engineers at the University of Washington, it uses ever-present existing TV and cellular signals to provide the power and medium for battery-less communications. Read More

Smartphone batteries used to determine weather conditions

By - August 13, 2013
Smartphone batteries contain tiny temperature sensors, designed to keep the phone from overheating. While those sensors do measure the heat generated within the phone, their readings are also affected by the temperature of the phone’s external environment. With that in mind, British app developer OpenSignal has created a system that allows multiple users’ phones to provide real-time, location-specific weather reports. Read More
