Japan is using piezoelectric floor tiles in busy areas like Shibuya and Tokyo Stations to convert footsteps into clean electricity https://t.co/oX01YqOAxh
@gunsnrosesgirl3 Those things are the worst power generation source on earth. Theyāre something like 3Ws per step, so it would take a bit over 1.5 million footsteps to generate the same amount of power as one solar panel does in one day.

@gunsnrosesgirl3 Japan is leading the way in developing groundbreaking piezoelectric technology that captures the energy from people's footsteps and transforms it into electricityā¦ https://t.co/rjAwGiUnpD

@gunsnrosesgirl3 Return on investment (ROI) timeframe? Mean time between failures (MTBF)? Costs to install/retrofit? Costs to collect/store/deliver electricity? Looks like a great idea. But these usually happen at the expense of taxpayer funds. Those are always easy to spend.

@gunsnrosesgirl3 Given the average weight in the United States, we should be able to generate a lot more energy. Let us address the obesity issue in our country. Research insulin resistance and how we got here and what needs to be done. Wishing everyone success on their journey.
@gunsnrosesgirl3 This comment thread is full of a bunch of negative Karenās who canāt do math. Itās not about efficiency. Itās about the sheer volume of steps on a single tile every day. Is that number high? Yes or no
@gunsnrosesgirl3 @grok explain? https://t.co/fJ6Ky7M90V
Piezoelectric tiles use materials that generate electricity from mechanical stress, like footsteps compressing them. In Japan's busy spots like Shibuya and Tokyo Stations, these convert pedestrian kinetic energy into power for lights or displays. Pilots since 2008 yield ~0.1W per step, enough for small usesāinnovative but not a major energy source.
**The Fart-Powered Charger** **Concept**: A wearable energy harvester that captures the kinetic and thermal energy from human flatulence to charge small electronic devices, like a phone or smartwatch. Itās a bulky, embarrassing contraption thatās as impractical as it is humiliating. **How It Works**: - **Device Design**: A padded, airtight seat cushion strapped to the userās backside, connected to a small turbine and thermoelectric generator. The cushion is lined with sensors to detect gas release and motion. - **Energy Capture**: - **Kinetic Energy**: Each fart propels a tiny turbine in the cushion, spinning it to generate a minuscule amount of electricity (think 0.001 watts per blast). - **Thermal Energy**: The heat from the gas is absorbed by a thermoelectric patch, converting the temperature difference into a trickle of power. - **Storage**: The energy is stored in a clunky, belt-mounted battery pack that weighs 2 pounds and takes 500 farts to charge a phone to 1%. - **Output**: After a full day of average human flatulence (10-15 farts), you might get enough juice to power a smartwatch for 5 minutes. **Why Itās Stupid**: - **Social Suicide**: The cushion makes loud whirring noises with every fart, drawing attention in quiet settings like meetings or elevators. It also emits a faint LED glow to indicate ācharging.ā - **Inefficiency**: The energy yield is abysmalāthousands of farts are needed for anything useful, and the battery leaks charge if you sit still too long. - **Maintenance Hell**: The cushion requires daily cleaning to avoid odor buildup, and the turbine clogs easily if you eat too much broccoli. - **Aesthetics**: It looks like a diaper crossed with a steampunk fanny pack, complete with exposed wires and a āFartVoltā¢ā logo that lights up. **Use Case**: Imagine waddling around a coffee shop, cushion buzzing and glowing with every toot, while your phone stays at 2% because you didnāt eat enough beans for breakfast. Your friends stop inviting you out, but youāre āsaving the planetā one fart at a time. **Why Itās an L**: Itās a loud, smelly, heavy, and borderline useless device that turns a natural human behavior into a public spectacle for negligible energy gain. Perfect for someone who loves attention and hates dignity.
Piezoelectric generater has no moving part. This Japanese floor has moving parts and people will be tired after walking on the floor since human energy is converted to electricy due to conservation of total energy . Who transfered the energy to electricity circuit? Answer is the peope walked on this selonid generator not piezo which generates much more less energy then selonoid.
@gunsnrosesgirl3 This isn't good. It's gimmicky like all 'green energy projects'. These things wear and tear, they're weathered by rain, they wont last long, & replacing/transporting the expensive materials costs energy. There is no 'quick fix' for thermodynamics. Nuclear is the only option.

@gunsnrosesgirl3 This is how the calcium carbide lamps used by miners in the past worked https://t.co/WZFP3dRbJr
@gunsnrosesgirl3 No they arenāt. The amount of electricity it creates is tiny. Think from first principles. Itās a very small amount of physical energy being discharged and then how much can actually be converted is a small fraction.
Extract from my conversation with Grok about the laws of physics relevant to energy - we are basically getting pedestrians to inefficiently burn more energy in order to inefficiently extract energy: 4. Net Energy Loss: - From a thermodynamic perspective, this represents a net energy loss because the human body is not a perfect energy converter. The human body converts chemical energy from food into mechanical energy with an efficiency of around 20-25%. Therefore, if a pedestrian uses 10 joules of mechanical energy, they might have consumed around 40-50 joules of chemical energy from food. The piezoelectric tile then converts only a small portion of that mechanical energy into electrical energy, resulting in a significant overall energy loss.
A clean way of energy conversion Placed on routes people traverse on a daily basis, constant electricity is assured and for an area as busy as Shibuya this would work so well Peak invention and application š«” I imagine what will happen if they are placed under a carpet grass on a horse race track, will it have the same effect?
