Yes, an energy generating playground can produce electricity, but only in small amounts. The technology captures the mechanical energy of children playing—spinning, swinging, or stepping—and converts it into a charge that typically powers LED lights rather than feeding the main grid.
The primary purpose of these installations is rarely financial return on energy sales. Instead, they serve as tangible educational tools that demonstrate how human-powered energy works, or as a practical power source in remote communities where there is no grid.
How it works
The principle is straightforward: human movement is mechanical energy. When a child pushes a merry-go-round or steps on a tile, that motion drives a generator. The electricity produced is usually stored in a battery and used later for illumination.
For a merry-go-round, the challenge is speed. A roundabout turns at roughly 10 revolutions per minute (rpm), whereas a conventional generator wants 700 to 1,000 rpm. The solution is gearing. The Empower Playgrounds system uses a gearbox, run in reverse as a speed increaser, to raise this to 200-300 rpm. The hardware chain described in 2010 involves a Land Rover hub axle as the main bearing, a helical gearbox, and a three-phase AC generator. A bridge rectifier ensures the system works regardless of which way the roundabout spins. By design, only about 30% of the children’s play effort goes into generating power, so the ride stays fun rather than becoming a work wheel.
Other designs take different approaches. The “Energy Carousel” in Dordrecht uses rope swings on a tensegrity structure. The mechanism resembles a bicycle dynamo, storing energy in a battery beneath the play area to light up the structure in the evening. The lights glow brighter with faster play and change colour based on the day’s total energy harvest.
Kinetic floor tiles represent a different route to electricity. Pavegen says its tiles move down 5-10 millimetres per step, and that this movement is turned into rotation that drives electromagnetic generators. Similar kinetic flooring is used for energy-generating dance floors.
Real-world examples
Empower Playgrounds (Ghana and West Africa)
This is the best-documented example of a working system. Founded by retired engineer Ben Markham after an 18-month volunteer stay in Ghana, the charity installed its first merry-go-round systems in 2008. By October 2013, 31 schools had these installations, each equipped with 50 LED lanterns.
The charity’s own impact figures (viewed in 2026) list 70 merry-go-rounds and 40,845 students reached since 2008. The power is not used for the playground itself, but for education. The batteries charge “Tough Light” lanterns that pupils take home to study. Up to 200 children per school share the lanterns in groups, bringing them back to school every two or three days for recharging.
The system has evolved. Solar panels are now connected to the batteries to keep them topped up during school holidays when the playgrounds are empty. The charity has also expanded into classroom blocks, libraries, and boreholes.
Other global installations
In the Netherlands, the Energy Carousel (2012) by Ecosistema Urbano demonstrates how play can control lighting. In Singapore, a temporary “Energy Playground” by Kinetics Play at Singapore Design Week 2024 featured a pedal cycle powering a hologram fan and solar panels on top of a slide.
Kinetic tiles have also been installed in schools and public spaces. Pavegen, a London-based company, had tiles in a Kent school corridor by 2012. Pavegen and Shell also placed tiles under a football pitch in Lagos, Nigeria, to power floodlights (reported in 2016).
However, not all products survived. The Soccket energy-harvesting football, which its makers claimed would give about three hours of light from 30 minutes of play, suffered from durability issues. A 2014 report found that 8 of 10 families interviewed in Cuetzalan, Mexico, said their balls lasted from a couple of days to a few months, against a claimed three-year life.
The UK context
No dedicated public energy-generating playground was found in the UK. The closest equivalents are kinetic floor tiles in school corridors, such as the Pavegen installation at Simon Langton Grammar School for Boys in Canterbury, and outdoor gyms that generate power for their own lighting. Pavegen itself entered administration in September 2026.
What the numbers say
The output of human-powered play is small. The founder of Empower Playgrounds stated in 2010 that it takes two to three children to produce 100 watts. At the early prototype stage in 2007, claims reached up to 350 watts, but this required 40-60 students playing actively.
To put this in perspective, 100 watts for one hour equals 0.1 kWh. At the GB price cap electricity unit rate of 26.32p/kWh (from 1 October 2026), that hour of play is worth roughly 2.6p. Even with dozens of children playing, the financial return is negligible compared to the cost of the equipment.
Figures for kinetic tiles vary: Pavegen quotes 2-4 joules per step, while the Institution of Mechanical Engineers put it at 1-5 joules in 2016. At 4 joules per step, you would need roughly 900,000 steps to generate 1 kWh. While the energy is real, the volume is low unless you have thousands of people stepping on the tiles daily.
Limitations and honest assessment
The main limitation is that play is intermittent. Children play at specific times, and weather and holidays affect use. This is why the Empower system now uses solar panels as a hybrid backup.
Maintenance is also a factor. The Soccket ball failed because it could not withstand the rigour of daily play. Outdoor kinetic tiles must withstand rain, dirt, and heavy loads. Michel Smit, chief executive of Energy Floors, said in 2020 that kinetic energy outdoors had proven not to be efficient because it takes more energy to make and maintain than it produces, which is why the company uses solar tiles outdoors.
However, the technology has value in off-grid settings. In Ghana, the playgrounds provide light for homework where the alternative is no light at all. In schools, they offer a hands-on lesson in energy conversion. For a grid-connected park in the UK, in our view the educational value outweighs the electrical output, and a single small solar panel would usually produce more electricity than a playground generator.
The UK angle
The UK has seen kinetic energy in other forms. The Hull “Green Heart” outdoor gym in Shaw Park, opened in 2012, uses energy cross-trainers and hand bikes to power its own lighting. The company behind it said each piece of equipment can produce 50-400 watts.
Pavegen, the kinetic flooring company founded in London in 2009 by Laurence Kemball-Cook, had tiles in schools and at public events. It entered administration on 30 September 2026; what happens to the business next is not yet known.
“Sustainable playground equipment” usually means equipment made from recycled materials or by manufacturers using renewable power, not equipment that generates electricity.
Frequently asked questions
Can a playground really generate electricity?
Yes. Empower Playgrounds’ merry-go-rounds in Ghana have been generating electricity for students since 2008. The energy is stored in batteries and used to charge LED lanterns, but the amount is only enough for lighting.
How much electricity does an energy-generating merry-go-round produce?
Typically, two to three children produce about 100 watts while playing, according to the founder of Empower Playgrounds (2010). Early prototype claims in 2007 suggested up to 350 watts, but this required 40-60 students playing.
How much energy does a person produce by playing or exercising?
An average healthy adult can sustain roughly 75-100 watts. On a generating bike, output is often estimated at 50-150 watts. Even with many children playing, output stays at the scale of LED lanterns, not buildings.
Are there energy-generating playgrounds in the UK?
None was found as a public playground. The UK has kinetic floor tiles in schools, such as the Pavegen installation in Kent, and generating outdoor gyms like the Hull Green Heart.
Is kinetic play energy worth it compared with solar?
For grid-connected parks, mostly no. The energy output is small, and even companies in the field use solar outdoors. Kinetic playgrounds are best suited for educational purposes or off-grid applications where the alternative is no light at all.
How much does an energy-generating playground cost?
The Empower Playgrounds merry-go-round system cost about US$10,000 according to a 2013 report. Pavegen tiles were priced at around £1,250 per square metre in 2015, with a target of under £600 for 2016; no current price is published.
