I was enlightened about this Battery Less wonder. This is a boon for rural areas and an emergency tool which depend only on your will and your tendons. Learn about supercaps, dynamo and White LED's here.
"Ever been stuck needing an illuminant, but with no batteries or power source to hand? then check out this article by Richard J. Nelson on the LED Forever Flashlight."
This is a Linear Dynamo LED Torch which uses a SuperCapacitor to store the energy. Easy to repair and maintain if necessary.
It uses no batteries and requires only the single LED included. You can even leave the flashlight unused in your car's glove box for years and you'll always get that all-important light when you need it most. Forever Flashlight lll pays for itself quickly by saving you the cost of batteries and bulbs.

Here is the first page that will interest you - Parasitic Power Shoes Project
"environmental energy sources can begin to replace batteries in certain wearable subsystems. In this spirit, this effort has examined devices that can be built into a shoe, (where excess energy is readily harvested) and used for generating electrical power "parasitically" while walking."
Piezoelectric Energy Scavenging In Shoes
Goal: To develop a rugged piezoelectric shoe insert and complementary conditioning electronics for unobtrusive, parasitic harvesting of the compression energy normally lost while walking

The goldcap-Dynamo Lamp idea is a DIY Tutorial by Kainka on Electrical Energy Harvesting. What may be this EH Thing ?
Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks. - EH at Wikipedia
Then the Cycle Dynamo may not be the ideal choice for furthering this research. The reason being, this is quite a powerful source of energy, especially when going downhill!
We need a more fussy source of Electricity. Like the waves of the sea, that could splash onto Large plates of Springy Beryllium Copper Cantilevers, which moves an Array of Magnets in coils (Reverse of Solenoids). This gives Random Spurts of High Energy Pulses which have to be Harvested.
That is for you to dare and do ........ Now let me give some things you can read, before you start this epic Adventure...
- Energy Harvesting at TI
- Supercapacitor Contest: and the Winners
- SuperCap Battery of Kainka - Elektor
- Electric double layer capacitor an eFlywheel
Gomier Electric Tricycle
We need more contests, An LED Lighting Contest and a Sponsored Elekrik Vehicle (Non-Car) Super-Contest.

The MTM Scientific, Inc. Experimenter Corner
Highlights are How to Measure the Power Output of Solar Panels and the Time Controlled Relay Switching Kit.
They also sell a Battery Amp Hour Meter and a Crystal Diode set which contains 1N34A diodes, 1N60 and D9B for learning electronics. They are Germanium Diodes.
An interesting Energy solution is the Hand Cranked DC Generator Plans. It describes how to build a hand operated electric power generator using a standard DC gearhead motor.
Solar Tracker Circuit Kits helps you servo position your Solar Cell Array, you can build a device which will automatically follow the sun across the sky.
At the PackRat WorkShop Lee Bell has archived Power-Energy Ideas, Mechanical Howto and Robot Designs too.
Alternate Energy Plans by Lee Bell
A Practical Man, His drawings are a language by itself. He has created a useful resource which will keep a DIY Enthusiast busy for many months.
Alternate Energy, storing and managing your own small power source, are an invaluable asset for Home or Small Business.
Depending on oneself, not only develops skills but also keeps you in form always. Building an energy source cost-effectively, requires you to put in a lot of learning and building efforts.That itself may become your future Small Business
Remember Fossil Fuels are Running out fast, Only Internet Communications and Alternative Energy will keep Business Blooming.
The lifestyle has to change, The future Generations are going to face the Heat, or is it Bitter Cold ! Even Freezing ?
Coal and Steel with Steam brought about the First Industrial Boom. Then Oil created unprecedented Magic, the Second Technological Revolution. This will not last long.
If only Rover found Oil in Mars, this post was not needed.

Renewable Energy -Solar Electronics
Make a simple solar charger for 4 AA rechargeable batteries. In this article you will find out how to make a very simple solar battery charger for 4 AA rechargeable batteries using a small 6 Volt solar panel. A labelled photograph of the completed charger is provided at the end of the article.
Basic 4 AA Solar Battery Charger Plans
Here are very useful ideas on solar energy and frugal lighting techniques. Solar Energy goes with Frugal Designs and things like UPS Uninterrupted Power Supply and High Efficiency Circuits. Green and Small Carbon Footprint all finally means how Energy Efficient is our Lifestyle and Preserving the Planet the way we found it, without leaving any scars.
