How many volts can a human body generate?
Probably not. A human body can only generate between 10 and 100 milli volts [source: NanoMedicine ]. A cathode ray tube requires about 25,000 volts to create a picture on a TV [source: Physics Factbook ]. If the machines could gather millions of electric eels, on the other hand, they'd be well juiced up.
Why doesn't my computer work?
And it's not because your computer wouldn't work. It's because your brain wouldn't work. Everything we do is controlled and enabled by electrical signals running through our bodies. As we learned in intro physics, everything is made up of atoms, and atoms are made up of protons, neutrons and electrons.
What type of charge does an atom have?
Protons have a positive charge, neutrons have a neutral charge, and electrons have a negative charge. When these charges are out of balance, an atom becomes either positively or negatively charged. The switch between one type of charge and the other allows electrons to flow from one atom to another.
Is sodium a positive ion?
Sodium ions are positive, so the area immediately outside the cell membrane is positive. There isn't a strong enough charge difference to generate electricity, though, in this resting state. When the body needs to send a message from one point to another, it opens the gate.
Why is electricity important?
Electricity is a key to survival. Electrical signals are fast. They allow for a nearly instantaneous response to control messages. If our bodies relied entirely on, say, the movement of chemicals to tell our hearts to speed up when something is chasing us, we probably would've died out a long time ago.
What is the natural resting state of cells?
Negativity is the natural resting state of your cells. It's related to a slight imbalance between potassium and sodium ions inside and outside the cell, and this imbalance sets the stage for your electrical capacity. Your cell membranes practice a trick often referred to as the sodium-potassium gate.
How many watts does the human body use?
Note that this is 100 additional watts or mechanical power on top of the 100 watts used by the human body for breathing, pumping blood, thinking, digesting food and everything else. A human body requires power even at idle, doing nothing. Sleeping, sitting, whatever, about 100 watts at idle.
How does the body produce electricity?
The body produces electricity by creating , in the cells' membranes, a difference in concentration of ions. This is performed by biomolecular ion pumps, fueled by ATP (Adenosine Tri-Phosphate). ATP is produced in mitochondria, burning glucose with oxygen. The oxygen comes from the red blood cells (RBCs).

How much electricity does a bicycle generate?
Let’s start with some simple math. If one person were to hop on a bicycle generator for one hour, they would produce roughly 0.11 kWh. One hour of pedaling is no small feat (just ask any SoulCycle enthusiast). To start, you would be able to power one 100 watt light bulb for an hour. Fair enough. But powering your entire house for 24 hours is a whole different story. The average American household uses around 30 kWh per day. Since cycling on a bicycle generator for one hour produces about 0.11 kWh, we can use the following equation to determine how much electricity you can contribute to your home’s daily energy usage:

How many calories do you burn riding a bike?
If you pedal on an exercise bike for half an hour, the bike readout will probably tell you that you burned about 300 food calories (0.3 kWh). Of that, perhaps 75% heats you up, while a quarter goes into the bike, so you're putting in about 0.1 kilowatt-hours of electricity.
Why do people like working out?
After "helping the environment" during their workout, they're likely to be less conscious of over-using energy the rest of the day, an effect called self-licensing.
What is parasitic harvesting?
Generating power from people’s normal activities such as walking is known as parasitic harvesting. One example of this in action is the nPowerPEG, a handheld tube-shaped device that clips to your belt and backpack and generates electricity as you move around, using a magnet weight, spring, and inductive coil. This doesn’t produce enough power for high wattage electronics such as laptops and tablet computers, but better energy efficiency and battery technologies mean the concept has great potential.

But the “Reactor” is an iPhone case embedded with an ultra-thin generator that enables you to manually charge the battery by turning a handle plugged into the back of it. This method of energy generation is not a novel idea but the concept sheds light on how human-power can be a viable solution during emergencies and how effectively it is available on demand.
What is RB2B power?
RB2B, developed by designer Christoph Thetard, is a mechanical flywheel drive that powers a set of kitchen appliances. Pumping a foot pedal spins the flywheel at up to 10,000 rpm using geared transmission, with mechanical power of 350 watts. This power can run a selection of attached automated kitchen tools such as blades, a slicing disc and a whisk. Although it’s not clear how practical the device is, the designer still deserves credit for presenting a concept that challenges the idea that human-powered gadgets have to be portable and battery-powered.
Is human power renewable?
In some respects, human-power can be seen as the cleanest renewable energy source available, with great potential for helping people stay healthy and have fun. Here are four other notable products that shed some light on the future development of human power.
Fitness Level
- Your sustainable power output depends on your fitness level. Some elite athletes can maintain 350 W or more for more than 30 minutes. A fit recreational cyclist, you can probably maintain about 200 W, while the average, untrained person can produce about 100 W. It should be noted …
Age and Gender
- Your power output also depends on your age and gender. It increases up to about age 20, plateausuntil you're about 35, gradually declines to about age 50-60, then declines more rapidly after that. This is only a general rule, however; for elite athletes, power output appears to decreases gradually age 20: Men, in general, can produce a little more power than women, due t…
Multitasking Ability
- Doing something else (like working on a computer or watching a movie) while pedaling a pedal generator reduces your power output. If you attempt to make up for this by pedaling harder or faster, your ability to concentrate on the other task suffers. You cannot do both well at once. A 2014 studyinvolving 10 male college students and faculty members who took a 10 minute typin…
Environmental Temperature
- Pedalling in a stationary position at room temperature will make you uncomfortably sweaty after a few minutes, unless you limit your power output by pedalling more slowly or take some other measures to keep cool. Some of those measures may include: 1. work in a cool room, 2. wear cooler clothing (like shorts and a t-shirt), and/or 3. use a fan Usually, I need to use a fan. Assumi…
Generator Efficiency
- So far, we've assumed that all the power your body produces is converted to electricity. However, that is not true--pedal-powered generators are not 100% efficient. There are three sources of losses: 1. mechanical power losses - energy lost in the drive system that transfer the crank's rotational energy to the generator 2. generator losses - energy lost converting the rotation of the …
Conclusion
- The amount of electricity you can generate using a pedal-powered generator depends on a number of biological factors, like your age and fitness level, as well as the efficiency of the generator you are using. An average person capable of producing a sustained power output of 100 W can expect to generate from 31 to 74 W, depending on the efficiency of the generator sys…
