How feasible would homemade electricity generating machines be?

How feasible would homemade electricity generating machines be?
Not trying to totally live off the grid, just supplement existing energy with a bunch of little things like small homemade windmills or rainwater running past tiny turbines or something
Not even enough to charge a phone or something that eventually could charge a few car batteries?
Should say I have no experience in PrepHole, so I'd hope to learn by playing around of course

    It's actually pretty easy to setup power generation. The price ranges from $20 bucks to hand crank power an LED to $20K for an off grid system. Depends how much you want to spend.

    >rainwater running past tiny turbines
    Forget about this unless you have a fairly serious stream on property, with a significant elevation change. Ran the numbers a while back for another anon that wanted to do rain-gutter hydro. Producing 15 watts (enough to run a couple of LED bulbs) would only have been possible under hurricane level rainfall (>2in/hour). Even if you have enough flow through a stream, a pico turbine is going to want 10+ feet of head.

    Windmills are generally more feasible, but efficacy is strongly linked to size. There are smaller 10 foot diameter turbines that can do a kilowatt, but only at their rated speed (usually around 22-28mph). Those little vertical axis turbines you sometimes see on top of streetlights and stuff spend most of their life only putting out single-digit wattage.

        Really make you think.

    Unless you live in the far north, solar is by far the best bang for your buck, for a couple thousand you can have an (illegal) system that mostly powers a small home, for <$1000 you can have a smaller system that still generates a decent amount of power.
    Exception is if you have water flowing on your property, microhydro is more reliable power and cheaper than solar, at the cost of higher maintenance.
    Rainwater power is a terrible idea, small windmills have terrible cost efficiency.

    i use a 3x 450W solar panels to power a 5000W solar inverter based system with 10kwh of battery storage. during summer here in the north it has been more than enough to power most of my needs (fridge, laptops, powertools, phone battery banks, a few ligths and a vacumcleaner) it cost roughly 7000 usd and was well worth it. i will upgrade it with 2 more panels and maybe a battery in a few years. i am now looking for ways to generate more power during the winter months. found this guy with a tesla turbine and it looks very promising; https://m.youtube.com/watch?v=001z5ngc9WI

      Spamming solar panels is becoming a viable winter strategy as they approach $0.2/Wp. You could have 15kWp producing 5-10kWh/day on overcast winter days.

      Install mirrors to catch more sunlight and focus them into your solar panels.

      Cover them in summer so your panels don't get too hot.

        Solar panels might be cheaper by square meter than hardened glass mirrors

      Why a 5kw inverter for only a 1.3kwp system? That is massively mismatched

        For future expansion of course.

    yeah solar is the cheapest and most effective with good batteries. it cost a ton to install , but if your smart you can spend 10 on a 20kilowat system, it will run most machinery,

    the chinks flooded the world with cheap solar systems lol

    but there also systems that utilize solar wind gas and thermal all at once, your enviorment plays a role. but solar is just to effective

    It's easy with a little planning. You just need to find an apartment complex with free water. I use the free water at my apartment to sustain a reservoir that I built in the bathroom that runs a small hydroelectric generator which creates electricity that I sell back to the utility company. Last month I my brother-in-law even brought in a water truck and filled it up for his pool. 300 bucks cash, easy money..

      I had to heat my apartment one winter by leaving the hot water running. Place was fucking freezing.

    It’s called a generator. They are very simple and cheap machines

    Nah, ngl OP, I don't think you're going to be able to build that.

    Can be done. We had a comfy wood gas generator a while ago, look up info there.

      solar all the may unless you live next to a waterfall. its the cheapest and current 18650 batteries are overkill for sensors and small modules. The catch is the initial cost but it'll pay itself if you are smart.
      also

      >just supplement existing energy with a bunch of little things like small homemade windmills or rainwater running past tiny turbines or something
      completely pointless, but it doesn't matter, you won't do it.

    are 18650 cheaper than buying a deep cycle battery and how is the discharge in comparison?

      Deep cycle lead acid is absolute garbage compared to any kind of lithium, but it is cheaper to buy initially. It's not cheaper over time when you have to replace it after 5 years or less.
      What you want for energy storage is LiFePo. Self-discharge is generally very low.

    Build a turbo burn barrel, and have the compressor suck off a shopvac for power.
