Human power Generation: In the future we will be our own mobile power

Electricity can be said to be the greatest discovery of human history, which forms the basis of all our modern life. Now the Earth, even the instantaneous world power outage, its consequences are unimaginable. As electrical appliances are increasingly being invented, therefore, human demand for electricity is growing.

For this reason, humans have tried almost every way to generate energy for power generation. Material combustion, water, wind, solar energy and even nuclear power, the total installed capacity has repeatedly exceeded the limit, the annual power generation is also climbing. But even so, around 20% of the world's population still has no electricity available.

As a result, more and more people began to explore new ways of generating electricity to make full use of all kinds of energy to generate electricity. For example, today we are going to discuss the topic: human power generation.

Moving not only makes you healthy, it also makes you power.

People have to move every day, whether it is walking, work, exercise, as long as the move, there will be a slight power generation. The energy produced by one person is negligible, but the energy generated by the 7 billion of people on earth, even if they are just walking, will be a considerable amount of electricity. So, someone really came up with the method of using people to walk to generate electricity.

The street lights on both sides of the road are partly powered by solar power, but the lumbar intervertebral discs of the Boulder Square in Lars XXX are particularly prominent. A company named Engoplanet has developed a clean-energy street lamp that connects the pedals with three mini-generators. Each time someone walks up to the pedal, it generates about 5 watts of electricity and is then transported to the battery.

> But it's not the first place to put the technology. In the past, Britain had already put this pedal into the super. Imagine how much it would contribute to human power if the technology was very mature. If a person is able to walk to generate electricity, what if it is put into a sporting event? For example, the opening of the World Cup, each of the turf under a piece of the NBA all the team stadium floor is replaced by a power floor, not only athletes can generate electricity, basketball hit the ground can also generate electricity, such as hundred meters sprint, everyone's track focus on a light bulb, run faster, the more power generation, light bulb ...

So, it's natural that people are proposing to use exercise to generate electricity. A gym in the United States uses the energy generated when people exercise to provide the venue with all the power needed for lighting. It is said that such a fitness generator if 20 people use 4 hours a day, one months will be able to produce 300多千瓦 electricity. And, while you're working out, you can see that your workout is growing at 1.1, and will the morale of the workout be more and more vigorous? Environmentalists are sure to like the invention very much.

Among the two ways to generate electricity from the human movement, fitness generation is the most discussed. Because fitness is one of the most energy-free and large-scale groups, and it is not a big problem to collect these energies. However, the reality has not been widely used.

The main reason for this should be the ratio of cost to return. According to 20 people one months to generate 300-kilowatt of the electricity, each machine one months will generate 15-kilowatt of the electricity, if the electricity is 5 cents per kilowatt, one months to send 7.5 yuan of electricity ... But the actual enterprise sells electricity to be cheaper. Then, the enterprise is really going bankrupt time also can not return to Ben.

Even if it is very environmentally friendly and effective, but for the enterprise, profit is the first. So, use it purely as a power generation, unless the cost drops very low. And now more is available to the B-terminal customers for cost savings.

Since the human body outside the value of power generation is very limited, should not use blood what to try?

A person with a fever may do something else, but the power line

Compared to running, walking and other visible power to generate electricity, using the body's internal organization to generate electricity is more high-tech. Some people may not understand: there is no air in the body, where to generate electricity? What do you use to generate electricity?

Scientists have plenty of ways to do that. Next we will briefly introduce several.

Blood generation. A crazy artist in Russia, Dmitry, has made a power plant to provide the power needed for his concerts. So what is this generator driven by? It's blood. The Dmitry batch pumped a total of 4.5 liters of blood from his body to maintain the device's operation. But is that what we want to say about blood generation? Of course not.

There are two main ways to generate electricity at present, one is to use the flow of blood itself to generate electricity. Fudan has implanted 0.8 millimeters of fiber into human blood vessels and then gained energy from the flow of blood. It inserts the fiber into the nanotubes and then connects a copper wire at both ends of the nanotube. When the blood is flowing, it can produce electricity.

Unlike blood flow, Japanese scientists use biochemical methods. It developed a fuel cell that uses the sugar in the blood to generate electricity. The enzyme that decomposes glucose in the blood is applied to the battery, and the glucose is decomposed to produce electrons that generate electricity. The advantage of this kind of battery is obvious, as long as people live, it has always had electricity.

Muscle movement to generate electricity. The maximum energy that the body can produce comes from the muscles, so the muscle power generation naturally becomes the focus of attention. Scientists at the Karlsruhe Institute of Technology in Germany have developed two ways to use muscle power. One is to bind a generator to the lower extremity, which is capable of generating electricity using a sensor composed of a moving magnet and a coil. By sensing changes in the body's center of gravity, the magnets move continuously and generate electricity. Another way is to put a liquid cushion in the shoe, through the flow of liquid will be constantly flowing, thereby forming a hydraulic pump inside the hose. In the repetitive movement, electricity is generated.

Thermal power generation in the body. There is a ze Baker effect in physics, specifically, when two different metals are connected together to form a closed loop, if the temperature of the two connection points is not the same, a tiny voltage can be produced. The greater the temperature difference, the greater the voltage will be generated. People are temperature-controlled animals, in the normal circumstances of the human body and the air will have a difference in temperatures. The temperature difference, then, provides the condition for the current to be produced. If a micro-generator is glued to the surface of the skin, an electric current will appear in the circuit. A body temperature flashlight named Lumen has been invented. The human body can produce 15 ma by touching the lumen, which is already sufficient to power the LED bulb.

Thus we can imagine the scene is that the human body in the winter to generate more electricity than in the summer, the peak of electricity than the foot of the mountain, the fever of people generating more than normal ... In the future, if you have a fever, you don't have to be sad, maybe someone else's cell phone is out of power, you can also because of a fever and give mobile phone more power ...

In addition, there are tears power generation, sweat power generation, urine power generation, hair generation, eardrum power generation and so on, it can be said that in order to generate electricity, human has been touched all over the body.

But also one might ask: the power generated by these generators may not be as much as a treadmill, do they really need to be developed?

I'm going to give a definite answer: yes.

What bike do you want? I'm going to make my own mobile power.

The first problem that can be solved by using human power is the charging problem of implanted devices in vivo.

Currently prevalent in the human body implanted in human health testing of micro-electronic systems, which can be achieved all-weather detection and reporting of human physiology, case level, thereby issuing corresponding instructions to provide people with early warning of human disease. Then, the use of blood-generating sublimation batteries can be said to perfectly solve the electrical problems of the electronic system.

And it will also be a great help in the supply of pacemakers, insulin pumps, and various implanted chips. At least no surgery. The main thing is that these devices, which are implanted in the body, are small in size and do not require much electricity to keep them running. The use of the human body to provide power support is no better.

Another possibility of human power generation is to turn a person into a living mobile charging treasure. Although a device has very little power generation, if humans can overcome all kinds of difficulties and implant all kinds of electricity into the human body without compromising their health, they will also get a considerable sum of electricity. These charges may solve your phone, watch, e-cigarette and other devices charging problems, the mobile charging treasure will be placed in the history of the display cabinet.

But these two points are faced with a common problem: power transmission. How can I send electricity from blood to a pacemaker or an insulin pump? Does the current in this process affect people's health? And to the second question, in order to transfer the power of the body outside the body, can not be inserted in the person of a wire to export it, that looked a bit strange after all. Then, the wireless charging technology must achieve a vigorous development.

It seems that human power is a distant thing, but it really happens in this magical world. After proving that these methods can actually collect the current and store it, we can say that we can do it. Just as human beings are moving from infancy to adulthood, human power generation technology is only in swaddling. The future is not known, but the technology will always maintain trust, should be the eternal enthusiasm of people.

After all, the current charging treasure is too heavy.
