Electric Generating Stationary Bikes (Human Hamster-Wheels)

Very interesting. This truly piques the engineer in me’s interest.. I’m with the idea 100% of the flywheel approach and it running around $100.. the kicker would be the battery bank and the inverter..
You could get some cost savings using an old bike as a donor for parts, and the larger the flywheel the better off you could be. (once it gets going momentum would help you continue the spin) Throw a decent transmission (from donor bike) in there and you can keep the speed controlled and wouldn’t need a voltage regulator.
Now tied to an existing offgrid setup.. like a Tesla Battery (Powerwall i believe they are calling it?) with a good diode.. That could be a great boon!
I am somewhat dubious of the “1 hour” thing as that’s extremely variable depending on usage of power and condition of battery; that’s more of a ‘sales’ point but the concept itself is sound as well as proven in other applications (the manual treadmills in gyms in the 90’s powering attached TVs come to mind)

That all said; there is another side to it that I would be remiss in not bringing up.. Unless you have a REALLY well made system you will lose energy to the inefficiency inherent in converting mechanical energy to electrical energy.. (not to mention the chemical energy (calories) required to produce the mechanical energy to convert to electrical energy.. so for like an off grid setup this would be great, but something where you’re trying to shave cost off of your utility bill the savings VS upfront cost would be somewhat hard to justify unless energy costs SUPER skyrocket or you are super efficient with your use of energy in the first place. Good source on that:

Bottom line? Do-able and valid, REALLY cool too! but unless you’re super efficient with your use of energy, have batteries and an invertor on hand or for cheap… not necessarily cost effective VS grid.

Electric Ceiling Light Details

Preparing to Install an Electric Ceiling Light

The following descriptions and photos are meant to help anyone designing or working on a ceiling, and using hanging electric ceiling lights.

1.  Design and build beams for the ceiling and lights to be attached. One important thing to remember is that ceiling lights cannot be installed directly under beams if the drywall (or other ceiling material) is directly secured flatly against the beams. The lights must be attached to the ceiling structure above the ceiling, by its electric outlet box. Then the box hole is cut into the drywall, and the drywall is secured to fit exactly around the light electric outlet box holes. Hint: it is far easier to do with another lighter material (not drywall), like for panels in a drop ceiling or a thinner fiberboard sheet panel.

2.  Inspect electric light for assembly

3. In this case the metal bracket attachment for the electric box, has a screw rod, with a loop cap. Unscrew the loop cap, and add a chain to connect the hanging lamp to the loop cap.

special note: as you can see in the photo of the instruction manual, they did not draw the wires.

Two pairs of pliers are needed to bend the strong chain links. Open them wide enough to link to the loop cap, and the hanging lamp. Then close the links.

4.  Feed wires through chain, and loop cap.

5.  Install surface of ceiling (drywall or other), cut hole for box. Secure metal bracket into box.

6.  This part must be done by an electrician when all power is off at the breaker panel: Pull line wires down from electric box, and connect them properly to the lamp wires, up through the metal bracket; including ground wire.

7.  Add plate guard to loop cap, and screw it into metal bracket in electric box. The plate guard will hide the edges of the hole in the ceiling that the wires come through. Make sure all connections are secure!

* Remember to hire a licensed electrician because it is the law, and you could be killed by electrocution.

Electric Dirt / Microbe Power

Microbes in Soil generate Electricity which is stored in Batteries!

These buckets of water and special fabric with wires are being used as batteries to store electricity from microbes in dirt. The technology now generates the same as D size batteries, and therefore already has market uses. The fact that we do not hear more about this in mainstream media, is yet another problem in propaganda that we need to address and change.
