Charged for Life on Video Production and LED Lighting
Can going green with battery charging by harnessing the potential power of joggers and Marathon runners benefit Video Production?
A wearable battery charger call ‘Ampy’ has gone on sale in the US. Worn on the arm, this device harnesses the motion of people such as joggers, marathon runners and sport by shaking internal magnets to generate current that is then stored in a re-chargeable battery. Three LED lights show the progress of the charge with 3 lights illuminated when the battery is fully charged. Meant as a ‘lifestyle’ product, this can then be used to power devices such as mobile phones and smartwatches. The development of Ampy has been funded by the crowdfunding ‘Kickstarter’ and additional funding has come from venture capital. However investors are complaining that the only sure way of generating enough current to charge a Smartphone is to plug Ampy into a mains socket which rather defeats the concept of using motion to generate power. Under test it was discovered that it would take about 36 hours of continuous activity to fully recharge the battery. It’s makers claim that they have sold over 7,000 units but it has gained a mixed reception from its customers.
Energy harvesting is an enviable concept and is at an early stage of its development but has a considerable way to go before motion energy could be utilised to self-charge the batteries of an electric car for example. However this may well be future of an energy source that is both sustainable and green. Available from Amazon, the Ampy costs about GBP90 (US$130).
Meanwhile Samsung has been carrying out its own research into using Graphene to increase the storage potential of the batteries in its mobile smartphones, resulting in a smaller battery but with an increased storage capacity of the standard Lithium-ion batteries. This would have advantages in other areas as well, for example producing longer lasting batteries for video cameras and powering the next generation of LED video lighting. Samsung claim that they are about 3 years away from producing the first generation of batteries using Graphene technology.
