The importance of renewable energy and other green energy have been increasing day by day and we get to see new technologies been developing each day. The most popular energy which is being talked everywhere is the green energy which has become so popular that every person wants to try their hands on it and there is no sign for its stopping. The trend these days is the development of clean energy using the human power. Human power is considered to be the ultimate power that can be used to do all sorts of jobs. This clean energy that is being developed using human power is quite popular and is being used worldwide. This idea was first given and started by a novelist named Frank Herbert who used the human power to harness the energy. There are various techniques available these days to do this sort of conversion. Here we are with a list of seven devices and technologies that harness human power for clean energy.
Nanotechnology – the science of managing matter at a molecular level – has delivered its promises: if charging your iPod with your heart is not great, then what is? Yes, you read correctly: it is your own little human heart that could be doing the work of a charger, so that you can continue listening to your favorite music.
How does this work? Scientists have created a revolutionary chip out of zinc oxide nanowires, which generate electricity when stretched. How many nanowires? They are so small that literally millions got to shape up the chip. All you have to do is stimulate them: movements as small as a heartbeat, a pinch of a finger or larger ones such as walking would do.
This could be enough, but it’s not the sole reason why the chip is revolutionary: it is also thousands of times more powerful than anything scientists have come up with in the lab.
To have an idea about how powerful these nanowires really are, it seems that five of these particles put together generate about 1 micro ampere output current at 3 volts, which in terms of voltage is comparable to two AA batteries.
Dr Zhong Lin Wang from the Georgia Institute of Technology, the head of the team who produced this discovery, feels the energy of more nanowires and nanogenerators could power larger electronics – for example cell phones: “Our nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination.” For these guys, sky really is the limit! …
