Here is a unique charger that can be powered both by solar power as well as by wind energy. The gadget has a built-in solar panel which coverts solar energy into an electric charge which can be used to charge your mobile phone, iPod, camera etc. A mini turbine mounted on the top rotates when placed against the wind and turns an internal dynamo which again generates electricity. The rechargeable internal battery of the gadget can also be charged by a normal ac charger.
The gadget is quite useful when you are travelling, trekking or camping. It’s one of a very few portable gadgets which charge by wind energy and is a perfect alternative to conventional charges, especially when you have no access to electricity. The gadget can be arranged on your motorcycle or jeep so that it directly faces the wind while you are driving. Under standard conditions, an hour of sunlight and a sufficientlystrong wind should charge your phone for about 30 minutes of talking.
The device has an USB port which can be used to connect it to an external power source such as from a computer or a vehicle power outlet. It also comes with a mini and micro USB tip making it useful for a vast variety of phones. A built-in LED power indicator shows the current power status
The K3 Solar and Wind charger is priced at $99.95 and can be purchased from the below link.

We all are familiar with the standard lithium ion batteries which are used in a variety of appliances in our daily life. The involve use of lithium compounds an as electrode. Lithium and similar elements used in such applications are not easily available and mining and extraction of lithium consumes a lot of energy which in turn adds to the carbon footprint of the battery manufacturing cycle. Also recycling lithium releases a lot of carbon dioxide into the air which in turn causes a lot of pollution.
Scientists at Rice University of New York and US Army Research Laboratory have designed a battery which uses Purpurin-a derivative of the madder root which is used in fabric dyeing. Madder roots have been used as a coloring agents since 3000 years and can provide orange, red and pink hues when used in different proportions
An extract of the dye-Purpurin is said to have properties similar to lithium electrodes such as carrying carbonyl and hydroxyl groups in the process of electrolysis. In standard batteries the electrodes are immersed in electrolytic solution and ions move from one electrode to the other creating a current. This current comes out of the electrode panels of the battery to run our appliances.
The core compound used here is chemically lithiatedPurpurin (CLP-where Purpurin is treated with lithium salts to create a material for the electrode) which is derived from the madder root. The project is being worked upon and it would take some more years for it to be made for commercial uses. However, it can for sure reduce our dependence on Lithium and cobalt metals for batteries and would also reduce the carbon footprint of the battery manufacturing cycle. Do watch out this space for more news on the Green Battery.

Vampire power is what you will examine after watching Robert Pattinson in ‘Twilight’ movie series. But it is not what it is at all. This is actually a term which is used by people for technology gadgets when we describe the power wastage and methods for saving it. When you have plugged your charger for charging but you are not using anything to charge, the electricity dribbles out of the electric socket like blood from neck of a punctured virgin and what you will see is a big old waste.
