Eventually, you might not need a battery or a conspicuous external power source to keep a device running for years on end. A team at MIT has created a device that produces energy by exploiting the temperature swings that occur between day and night....
When we think about ways to make existing power plants more efficient, we typically look at waste heat. It's something almost everything generates -- coal plants, automobiles and even your refrigerator loses a sizeable amount of energy to lost heat....
The PowerPot and the BioLite stove seem like great ways to harness the heat from fire and turn it into electricity. But what if you already have a pot and a stove? A company called Point Source Power might have a solution for you. The only thing that the company’s VOTO chargers need is a fire.
VOTO chargers look like one of those portable water heaters. But instead of a metal coil at the end, the chargers have a stack of replaceable fuel cells made from biomass. You stick this end into the bottom of your stove or bonfire and it will generate electricity over time. The electricity will be sent to its handle. There are a variety of handles, but the most useful one is shown in the video below. It’s a battery that can be used to charge devices via USB but it can also use its stored energy to power its built-in LEDs.
These chargers will be useful not only for campers and field workers but also for people who live in places that don’t have access to electricity. You can check out Point Source Power’s website for more info on their products, although the site seems to be down as of this writing.

There are a number of backup emergency power generators on the market that allow you to charge your iPhone or other smartphones without a traditional power source. Most of those involve consumables such as fuel cells or use solar panels that may or may not work depending on the environment. A new charger prototype has surfaced that will charge devices while you cook or boil water.
Working on a similar principle to the BioLite CampStove, the PowerPot also will generate power for USB gadgets using thermoelectric power. There are three different versions of the PowerPot, offering from 5W up to 15W of electricity for charging. All three concept versions put that power out through a USB port.
In theory, all you need is a heat source of any kind from a fire to a grill and you can generate electricity to recharge your gadgets. The pot also needs to be filled with water or watery contents to work. This would be the perfect thing for emergency preparedness kit for campers. The PowerPot could also be a very useful new source of electricity in developing parts of the world.
Check out the video below to see the PowerPot prototype in action:
The PowerPot is currently raising funds over on Kickstarter. A pledge of $99(USD) will result in the donation of the 5W model to someone in a developing nation. $125 or more gets you one for yourself, while $199 buys the 10W model, and $500 will get you and a family in need the 15W model.
