    Replacing batteries in toys and low current appliances with super caps and solar cells seems like an eco-friendly thing to do.  No more corroded terminals or dead batteries to worry about…

    Super capacitors might be a good option for storing the static electricity in the atmosphere especially on a cloudy day, when mounted on height with one terminal of the capacitor grounded and the other connected to a conducting mast. This energy can then be delivered through DC-AC inverter to power the house.

    Most likely, it’s best application will be as solution to optimize photovoltaic and wind farms by managing/storing the pick energy production and use it for pick needs along the day allowing convencional systems to operate withing the best efficiency. There are thousands of applications that can be listed, from emergency systems, power tools, off the grid remote systems for communication, etc.

    Supercapacitor can be used in order to store and supply large amount of electrical loads via earth physical reactions using wing generators, photovoltaic panels or hydrogon fuel generators, this can be a great energy solution for houses and companies. An ideal Supercapacitor must be a value for money product, a solid state solution without containing unstable or rare chemical materials, electrolyt fluids and dangerous oxides.

    Building an audio amplifier with subwoofer as a home project. The quality of the capacitors would definitely impact the quality of sound and give a punch. Better quality capacitors would mean the circuit would be more stable and resilient even at peak loads,

      So let me try it here - Use the super caps to store energy harvested from shaking the device, or cranking the device. The caps are better are taking the variable, potentially high current in rush of the mechanism, and store it with less loss. So one option is to make the power harvesting device fit inside a regular AA, C or D cell space. then to power the device, shake it a bit (or a lot) and it will run for a while (or a long time) Never have to replace batteries again.

    In model railroading, we want to keep the interior lights ON inside the passenger cars.  We use LED’s
    and at present a capacitor of 1 farad but the LED’s stay on for only a few minutes.  A 10 farad would
    extend the ON time to well over 10 minutes giving a more realistic look to model train operations.

    My idea is to build a self charging fitness tracker!
    The application flow is as follows:
    >> Using set of low power sensors for miniature body sensing and data acquisition which are powered by suoercaps.

    >> Using copper coil bottle with aligned magnets through which enormous energy will get generated while running/jogging being tied to legs.

    >> This energy is stored in supercap is harnessed to power the circuitry for long time and send fitness datas to smartphone via Bluetooth Low Energy (BLE)

    Eagerly looking forward to make this work with ultra cool supercaps!!
    Thanks.

    Many devices have non-rechargeable backup batteries that die at inconvenient times, losing memory.  One such is your typical lawn / garden sprinkler.  They are a pain to set up for time / date / watering time on / which days / etc.  Most use coin cell backups or really feeble caps that are only good for a short power outage.  A supercap is a natural for this and similar applications. 

    Cost might be an issue, so I suggest that the manufacturer supply whatever value they see fit, and provide an extra cost option for larger caps.  A battery-like holder can be molded into the controller and the capacitor leads cut so they are unequal length, with the positive (for instance), longer than the negative.  Contacts would be staggered so reverse polarity isn’t possible.
