Imagine that your mobile phone never ran out of battery, you didn’t have to think to charge it up and wherever you went it would always be topped up: that’s what the future will hold.
Wireless charging has been round for a while but has failed to fully break into the consumer market, but the number of inventions built around charging your phone with new technology being dreamed up by scientists and engineers is ever-increasing.
If they get their way and even half of the crazy charging inventions become a reality, then we’ll never have to plug our phones into the wall charger again.
In short, science is great, and here’s some of the most bizarre and brilliant ways you could be charging your phone in the future:
If your phone dies on a night out when you’re in a bar then just pull out this device and use your beer, coffee or beverage of choice to re-charge your phone.
The Epiphany onE Puck claims to ensure your phone will never die again while being tiny, lightweight and portable. The device works with either hot or cold energy.
It managed to raise $132,000 when it was on Kickstarter, and Epiphany Labs, the company behind the device, says it will begin shipping this month.
Charge while you walk
Even something as simple as walking can be harnessed to create power that could one day re-charge the battery of an empty phone.
Researchers for the Georgia Institute of Technology have created a self-charging power cell that converts mechanical energy to chemical energy.
They say that anything that involves mechanical energy, including walking, could provide power when using the cell.

Power up from thin air
We can’t see it but there’s a lot floating around right in front of our eyes, and in recent years this has included an increasing amount of power from wireless signals.
Scientists from Duke University, US, have created a cheap way to harness the loose power. Their device converts microwave signals to direct current voltage that can recharge a phone or other small device.
The technology used to harvest the power could also be used to collect energy from other sources including satellite signals, Wi-Fi or sounds.

Teeny tiny windmill power
A minute windmill with the ability to fit on a grain of rice could provide power for electrical devices.
In fact the windmills are so small – only 1.8mm at their widest point – that up to ten of them could squeeze onto a single grain of rice.
Wind created by moving a phone with tiny devices on would generate the electricity that could be collected by the phone’s battery. You can see a video of a windmill in action here.

Power up with vibrations
When you throw your phone down on the passenger seat of your car and drive off, the vibrations from the car automatically charge you phone.
Engineers from the University of Wisconsin-Madison, US, have created a nanogenerator that can harvest and convert vibration energy.
These vibrations could be from any source, from a vehicle’s engine to an overly zealous washer/dryer.

Rice-based phone batteries
Rice husks could well become standard ingredients in batteries. While not being a way of directly recharging your phone, the husks could be used to power batteries.
The outer-shell of rice is made up of 20% silica, an oxygen and silicon combination.
The silicon could be used for high-capacity lithium batteries, giving products such as mobile phones and laptops a longer time between charges. The researchers behind the advances have apparently already received interest from battery makers.
