whats the differance

Would this apply to UK residents?

Hoping to win🙏🙏🙏🙏

replace car battery with small car battery +super capacitor

Looking forward to see replacement of normal battery with supercapacitor

IoT mobile devices with small caps instead high capacitance battery

Hope to share my idea, although it may be expensive initially but in the long term its eco friendly

Looking forward to the final announcement

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…

Drive the actuator back to close position when power fail.

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.

nice giveaway…...

I can’t send my idea.

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.

Interesting giveaways, looking forward what will happen ...

good luck for every one !!!

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.

Automatic chicken coop control

Nice one and needed too.

Replace Lead Acid automotive battery with SuperCap + dc/dc + Li-Ion battery.  Cranking power from the SuperCap, Energy storage from the Li-Ion.  Dc/dc is used to control charge and discharge the Li-Ion battery.

Develop a high voltage amplifier for LIDAR

Would love to use supercaps in a bot, but I can think of a million uses.

What we have to do here? I don’t understand the requirements!!

Battery management system needs supercapacitors

My ultra cap is ultra-cool.  - 70 degrees C cool.  I am using an ultra cap to hold power from solar cells between transmission from high altitude (40,000 feet plus) amateur radio position beacon.

A Must have

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 many dumb/childish comments… so-called “engineers”, more like wannabe kids

Where can I see my submission? I was intending to add more details and it just went and submitted it. Now it says I’ve already joined this giveaway, but my submission is incomplete.

i want to design four legs inverter to reduce output harmonics.

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.

Storage energy from a modified windmill. Then use this energy to power a wifi link to monitor water levels, etc, from de system.

This is Great!Z

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.

First EATON’s 4x4 Winch Voltage Support System (WVSS) / We are an autonomous public university located in Caracas, Venezuela. Is our hope that we are eligible for this contest, considering our geographical location. In teamwork with our EE students, we have developed a winch voltage support system and successfully tested it in the field (Venezuelan Amazon) on a Land Rover Discovery 1 (equipped with Warn Winch Systems). The idea is to use the EATON solutions (XVM Supercapacitor module), integrate them to the winch system, and provide part of the initial transient current required by the winch and thus stabilize battery voltage (the winches usually starts in full voltage mode shortening the 4x4 battery’s duty cycle). We can send you further results if required.

Simple Power Ride-Thru:  To allow some on-board devices like intelligent flash devices to complete their internal processing, provide a super-cap with an isolation diode for all ride-thru devices.  This allows several seconds for those devices to manage internal completion due to any abrupt power-off of the overall system.

My 3KW inverter with this supper caps will be bossing efficiency.

Use as an energy source backup to close a valve using a motor when power is cut. Much longer life than a battery and it is a single use before recharge.

where I can load my idea?

BMS needs super caps for 7S X 3P configuration. Would be nice to try out for LEO applications

Battery Assimilator…..Resistance is Futile…..This project manages the Lead Acid Starter battery,  diminishing the effects of its internal resistance via voltage augmentation with parasitic drain shielding.  It is prototyped and proof of concept is achieved. I employ microcontroller intelligence with AEC101 augments. Super capacitors also offer improved transient voltage protection during engine start. Overall operating current consumption is about 7mA with additional smart SuperCapacitor maintenance at about 2.4V for longevity. Smart control requires just 2 (2.7V to 3.0V) Low ESR Super Capacitors (Yes just TWO) for a 12V augmented internal combustion engine electrical subsystem.

Product design, schematic, PCBA, firmware are all in place. PCB dimensions are 11.0cm x 5.0cm, single sided.

Battery/supercap combo to drive solenoid with smaller battery.

Appropriately sized supercap bank to power WiFi radio and IP camera during dark time after charging from solar.

A low voltage bistable valve (1/2”, for irrigation) can be managed by a supercap + solar cell. The supercap (0.47uF 5.5V) can power a microcontroller for days if it’s cloudy; the solar cell charges the supercap in few minutes. The microcontroller is able to control the valve if the charge is sufficient (always during sunny days).
Project developed as a hobby. Low-cost BoM, design, software, and first prototype ready.

Alnico re-magnetizer.  Alnico magnets have innumerable uses (guitar pickups, horseshoe and bar magnets, magnetos in combustion engines, and all high-temperature applications like laboratory heater/stirrers where Nd magnets fail).  Unfortunately they do de-magnetize over time.  Magnetism can be restored, but requires an enormous pulse of energy from an electromagnet - more than 70,000 Amp/turns.    Consequently a large number of turns and/or a large current pulse are required.  I believe supercapacitors could be very useful in this application.  With their high-current pulse capacity they would permit a reduction in the number of (expensive, bulky) copper turns needed to build a re-magnetizer for these classic magnets.

Circuits / circuit is already used in every electrical things but not used in car to charge the automatic car through mobile . For example I sit in the automatic car and my destiny is to far my car battery is dead between my destiny how could I charge ? When we create a Bluetooth car battery chargeable circuit , then ,when my car battery is low the then the LCD show a changing option by phone by Bluetooth and also add in the circuit whenever the battery is low automatic car stop and convert into its manual stage then man drive the car and the battery is on charge through Bluetooth . Also same in the air plane

what do you think of and I patent this idea… a universal charger like these capacitors and an outlet at the end

Another application would be in automotive: a secondary engine starter power source.. supercaps can provide greater current (less ESR) at low temps, compared to lead-acid. They could be charged up during operation, switched out of circuit when floating, then reapplied to B+ when ignition is applied.

My idea is to sell Eaton supercapacitors in a bundle together with the “solar harvesting into supercapacitors” board that I am already selling online. https://www.tindie.com/products/jaspersikken/solar-harvesting-into-supercapacitors/

I could use in my digital control spot welder design. Andy

Fun projects here.

I come from India with Agriculture back ground.
Electricity availability is an issue in farmlands.
A product which can inform an agriculturist when quality power is available to run water pumps helps water management.
With the help of super capacitors, it informs via GSM SMS when there is a power failure.
Motor run time information is captured at after power failure provising data for maintenance.

While this task can be done with battery also but it requires battery charging circuit and batteries have short life spans.
We need maintenance free products for farmers in far flung areas.

I was expecting to submit an article expounding the details of the circuit idea.

A glove with a copper plate as a knuckle spot, and a supercapacitor that is attached to a graphite rod which will heat up the copper, for more effective punches. The supercapacitor will charge fast so that you can stay in the fight longer. Meant mostly for police or other legal purposes(technically considered brass knuckles).

To increase the capacitance of a capacitor we can do the following

1) Increase the area of plates as much possible

Then 2nd step being the main step

2) apply the insulator on all the 4 sides of the plates (not the front and back) and paste it with a metal (from both sides) which is covered with insulator from all the sides(including front end, facing inside)
Then fill the inside area with strong insulation

This helps in increasing the capacitance inside by reducing the fringing effect and converting the capacitance wasted outside to be inside the required area

The idea is to use supercapacitors connected in a particular configuration (series and parallel) as an alternative to braking resistors used in VFD for industrial applications. Due to the high current charging capabilities of supercapacitors, we can quickly trap the kinetic energy of the motor while stopping the motor in a very short time. It can be pictured as a supercapacitor break whose function can be extended to feed in the recovered energy back into the VFD when needed. The charged capacitors can be used as a high surge current input for starting motors without the need to run the motor in a delta configuration.

Have a wonderful

Raspberry PI smart UPS (UN interruptible Power supply) - only one with smart battery management .

Interesting giveaway

The best use case for the super capacitor is power bank. The most important feature of super capacitor power bank is fast charging. Even though the power bank is bulky it will not be a problem for most IoT projects.

wondering if i put enough of these together, i could simulate a residential storage system

I want to use super capacitors to make a battery free my new anti theft device. I have a patent on it and i am in the process to design and manufacture it.  The market is huge, from rental car agency, to car dealers and truck companies. You do not want to get stuck in the middle of midnight in the middle of nowhere, at minus 25 degree, just because the battery of your remote went dead. A super capacitor will instant charge at start and will be good for years. No maintenance to keep track and change it. Huge market.

I’m designing a water leak detector.  It has to rotate a ball valve if a leak is detected, and must work during a power outage. A Supercapacitor and gearmotor is working great.

Supercapacitors are a type of new energy saving and conversion equipment which is meant to have the potential of high power density, great circulation feature, rapid discharge-charge, poor self-discharging, safe working and low cost. Different porous materials like porous carbon, NiO and Fe-Mn-O composites are used for fabricating supercapacitors owing to their great electrochemical characteristics. Supercapacitors are categorized into two kinds including pseudocapacitive and electrical double layer capacitor or EDLC. Attributes of EDLC is controllable by the connection area between electrolyte and electrode materials. Pseudocapacitive, as a supercapacitor, can save charge by an electro-activation process. Mesoporous MoS2 can be employed as an excellent pseudocapacitive material due to its large capacitance.

Supercapacitor are used in order to store power supply in it for any other purpose later but it can’t be overloaded because if it is it can become spoilt or damaged

Great power reserve when the UPS battery starts to run out, so that the backup power plant has time to start.

Mining Survey that records orientation via charging cap then sending instrument down hole

Use in electric cars along with batteries to assist in high demand situations!

Time released V + A for storage use

hope a set of super caps

Like to see how well the super caps will work in combination with LiPo batteries to provide power backup for a solar powered remote camera setup.

Smart Living-Plant based harvesting energy System with Supercapacitors:

The main Idea is to take into consideration the energy from living-plants by means of DC voltage form, which would be useful for several applications. For instance, in agriculture 4.0, smart living-plants at home and commercial centers as well as emerging technologies to transmit data. In addition, it could be applied in basic tasks such as feeding some residential loads / equipment. In this way, the energy harvesting concept is considered such a way that it would be possible to provide a monitoring system of the plant in real time, via microcontrollers communicating with an online / IoT platform. Some data of interest to be collected would be: of sunlight received, amount of water present and obtaining wind strength data. Then supercapacitors would be an essential device to storage some energy amount.

Supercapacitors offer a chance to make automated external defibrillators (AEDs) longer lasting and more reliable. An AED already makes use of capacitors in series to deliver a high voltage and high current shock to a patient’s heart. Regular capacitors are well suited for this because of their high working voltages. However, AEDs need a battery source to charge these ordinary capacitors. We all know that battery packs degrade over time. Can you imagine counting on an AED to help save a person’s life, only to find that the battery no longer holds a charge? A bank of supercapacitors could save the day! The duty cycle of a supercapacitor is much much longer than any battery. By having an AED constantly plugged into an AC outlet, the bank of supercapacitors will always be ready with a charge. When needed, the AED can simply be taken off the charger with enough power to treat a patient in an emergency. An AED could be ready to serve for many years without the need to replace or check the state of a battery pack. AEDs with supercapacitors as a power source would be robust enough remain reliable in much colder or hotter environments than those who rely on battery packs. Supercapacitors have the potential (pun intended!) to make sure AEDs are ready for action in many situations!

[For some reason, the contest indicated that I had already entered. I had not posted my idea though. It looks like someone else had this problem. I hope this serves as my entry. Thanks]

The typical voltage of the power source that feeds telecom equipment is 48V, but the actual voltage can range from 40V to 60V or even beyond. A telecom dc/dc converter (brick) would operate in the 36 to 80V range. During a brownout, an input voltage can drop to 0V for a few seconds disrupting the transmission of many Gbits.
Using capacitive storage that connects to the brick’s input is an obvious approach to overcoming this problem. Let’s calculate the capacitor’s value for a 10KW telecom rack assuming an operational voltage before the brownout is 40V, and we can’t drop below 36V for more than 1 second. The energy (E)released from a capacitor (C) is E=C*(V1^2-V2^2)/2, where V1=40V, before the brownout and V2=36V- the lowest operational voltage. The cap value would be ~66F. But if the cap is charged to 80V, the energy proportionality to the voltage square gives us C=3.9F or ~17 times smaller value capacitor. A module of three 65F/16.2V connected in series gives us a ~22.3F/48.6V module. Connecting two modules in parallel during normal operation, and stacking them up in series, when the brownout hits the rack will result in ~11F, rated to 97V but charged to 80V module, and will do the job. Changing configuration from series to parallel would require 4 switches (similar to a classic charge pump), but it is an easy job. The switches would introduce some small losses. 
This approach works not only when the voltage can be doubled. As a brownout is a relatively rare event, a low power HV source can charge a capacitor that will be connected when the input voltage falls below the minimal input threshold. The bottom line: the physical size of a capacitor is roughly proportional to C*V, while the energy stored is ~C*V^2.

Supercaps excel at “energy harvesting” applications where energy is absorbed slowly but released rapidly.

This application uses a supercapacitor to store energy from a solar cell to power a small insect-like robot that is propelled by four or six Nitonol Muscle Wire Legs. The system slowly charges up a supercapacitor until it has enough power, then discharges it suddenly to move a few steps in a burst. In bright sunlight, the robot would move every few seconds; on a cloudy day, the robot might take all day to move down a driveway.

Nitinol is a type of Shape Memory Alloy that can be stretched at room temperature, but returns to its original length when heated by an electric current. The length change that occurs is modest—three to five percent—but this is sufficient to build simple leg-like actuators. Nitinol wires heat up and shrink quickly when current flows through them, but cool down much more slowly, which limits their actuation rate.

join for together in both .😁
