Footsteps don’t create much energy, perhaps enough to power lights.
I told everyone already about methane energy. People don’t use it. People are dawdling so that we keep using oil. The world economy is oil.
We need to make methane systems where the poop in the toilets is flushed into methane collectors. This would power cities without dangerous nuclear reactors. It would clean the environment much more than nuclear reactors since it would cause reduction in methane in the atmosphere. Methane motors burn 98% or 99% clean.

When the world realises that self-driving taxis can get you killed, so can be hazardous to your health..
.
..riding in a self-driving taxi is tantamount to putting your life in the hands of unknown others, who can manipulate the vehiclei that a particular person is in.
If one footstep powers 10 lightbulbs for 20 seconds, total footfall per hour or even per minute would be able to power buildings.. and that’s just one walkway.
.
..it seems that many countries use ‘biogas’ to quite a large extent - many people are pushing for contentious nuclear energy and wind turbines are costly and unsightly, so an eco-friendly alternative should have higher consideration.. plus, it would remove the need for UK water companies to dump waste into nearby rivers and waterways.
The picture you showed looks to be about 3x3 feet wide. Too large for you? Are you a munchkin? Otherwise how do you lay down in it?
it’s not a bed.
It should be. Its made of hard porcelain usually. The human primitives need to design a bed in which to lay down in. First problem is the primitives made the tubs too small. Second suggestion is maybe a start would be one of those inflatable pool cruisers, then fill it with sand so that it sinks instead of floats. Idk. Not perfect but its a start.
Most cities the poop you flush totally goes to waste and pollutes the atmosphere, it isn’t used for biogas.
ai says the output is paltry, feel free to get a second opinion. Their numbers seem absurdly low
The 1-2 watt-hours daily estimate for footsteps on a 10 m² solar-kinetic path in moderate-high traffic was conservative, based on typical kinetic tile outputs of 4-5 joules (about 0.001-0.0014 Wh) per step, assuming 1,000-2,000 steps per m² daily. Higher-traffic scenarios or vigorous use (e.g., dancing) can push per-step yields to 2-35 watts peak, potentially raising totals to 5-20 Wh from steps alone across 10 m². Real-world limits like efficiency (5-20%) and even step distribution keep outputs supplemental, not grid-scale.
Revised Step-Only Outputs
Low-moderate traffic (500 steps/m²/day): 0.5-2 Wh total for 10 m².
Peak heavy (5,000+ steps/m²/day, e.g., stations): 10-50+ Wh total.
Traffic Assumptions
Moderate-high means 10,000-20,000 total steps daily over 10 m², common in busy parks or entrances. Outputs scale linearly with steps but drop if steps are light or uneven. Pure kinetic systems rarely exceed these without denser traffic.
1 or 2 watt hours sounds not even worth the effort the cost to install and build the thing would never be paid off its not even enough to run one low power LED lightbulb or computer.
Nelko label maker. £15.99 on Amazon, probably the same in dollars, connects to your smartphone and prints labels through an app, loads of templates. Great little machine, I bought one each for most of my family..
..it’s a shower-x-soaking-tub and I can’t install it because my housing association renovated my bathroom -and downstairs toilet- which both look great and much more stylish, but they changed the dimensions of the layout in the process and now the new shower/tub won’t fit. I’m peeved about it but what can I do.
That shower literally gives a head to toe full-body massage, meaning all aches and pains literally melt away.
The new bathtub and shower looks great and works well, so..
.
There are inflatable and silicon-filled bath pillows, I haven’t seen a full-length version but I do have this one:
..they are installed in VHT (very high traffic) areas, with footfall in the millions.
Japan utilizes piezoelectric walkways in high-traffic areas like Shibuya and Tokyo stations, embedding special tiles that generate electricity from the pressure of footsteps, converting kinetic energy into small electrical charges to power local devices like LED lights, digital displays, and sensors, showcasing a form of micro-renewable energy harvesting for smart city infrastructure. This technology turns passive pedestrians into active micro-energy producers, demonstrating a practical, zero-emission way to support urban sustainability with everyday movement, say www.dundarlaw.co.uk and parametric-architecture.com.
hmm so the ai was wrong. the ai assumed daily steps of only 10,000 steps. if there are millions of daily steps then the tech is not worthless. if it only gets 10,000 steps its worthless.
On another note: home printers are pretty much obsolete now, due to the ink cartridges costing way more than the printer itself.. conning the consumer, as per.
It’s only black and white, but it does a nice job of printing photos anyway, if you’re OK with black and white. Has built in WiFi, the works, very easy to set up.
The advantages of laser over inkjet are:
Toner doesn’t dry up or clog if printer kept in a relatively dry environment, even after months without printing.
Toner costs around $80, all in.
Toner lasts a long time, 1200 pages at least.
Quieter and quicker.
Pages arrive nice and warm
Inkjet ink is one of the most expensive fluids on the planet. Prize racehorse semen is cheaper by the fl. ounce than inkjet ink.
If you do need colour, you just have to spend more, but it’s still a much better investment than a cheap inkjet, even after a single year of heavy use. Here’s the colour version, price is $259
It uses 4 toner cartridges instead of one. Replacing all the toner in that one would cost about $370, but you’ll get toner with it, and the colours never go down at the same rate, you will use more black for example. The software will tell you which to order, so it will only really be about $95 at a time. You can get around 1500 pages (colour photos or graphics) from a full set of cartridges, which is much, much more than you’ll get from an inkjet.
You get the cheap Chinese ink cartridges sold at normal prices, don’t buy the OEMs sold by Capitalist scumbags. Some American printers, especially HP printers are built to fail, one of the failure modes is the OEM ink cartridges.
Capitalism sucks. My HP printers keep failing, I’m going to research what printer company makes printers of quality.
it is not my AI, it is a LLM made and trained by someone else.
the AI failed because it assumed the step count was 10,000. The rest of its calculations were correct. I am still disappointed that AI is still not reliable in 2025. The AI i used is not the best AI available though, there are other AIs and paid AIs of higher intelligence than it.
The reason I use that AI is because it has no emotions, and is meant as more of an encyclopedia Ai, so I thought it would be more factual, so pasting replies from it seems more formal, but the other AIs with emotions seem kind of more intelligent than it.
.
And also, when im doing research sometimes i prefer talking to someone who has no emotions, so i use that ai often, but clearly it is not perfect.
