This Solar Powered Desk Fan made by Solar Technology has been crafted from perspex. The fan takes advantage of even a small amount of light from a desk lamp to turn its blades and keep you cool.

The Solar Powered Desk Fan is delivered in kit form, from pieces of laser cut perspex that can be easily slotted together by following the instructions provided.  The solar panel has been placed on the back of the fan, and though some thought should be used concerning the placement of the solar panel to take advantage of any natural or artificial light source, it is important to place it where you will benefit from the fans breeze. The solar panel is large enough to take advantage of even a relatively weak artificial light so is suitable for any office.

The desk fan is suitable for children aged 6+. It does make a decent learning aid to show the abilities of solar power, be it from natural daylight or from a desk lamp. The child will benefit from constructing the fan, learning how the parts go together and visually experiencing how effectively light energy is converted into electrical power to turn the fan blades.  The advantage to this device is that once children are bored of it, it can be ‘recycled’ into a handy device for any desk worker.

The Solar Powered Desk Fan costs just £29.95 plus delivery.

This Bicycle Powered Generator is a concept design by the designer Elizabeth Joy Wong for a way of converting kinetic energy into electrical energy for everyday use.

The Generator envisioned attaches to a bicycle, which is peddled to turn the wheels, which then spin a friction drum. This friction drum is then powering the alternator, creating electrical energy. The electrical energy will be then stored in a portable power pack so that it can be used to power many different small appliances.

The Bicycle Powered Generator makes use of some basic principles to turn your motion (kinetic energy) into electrical energy that can be used around the house. Though it will never be a lot of energy, the generator does allow you to replace some of your electrical needs with a sustainable source of power. Many households have exercise bikes within them, this concept should allow you to benefit not only physically from the exercise but also financially in savings. The concept generator would then help reduce a households reliance on unsustainable electricity sources, maybe giving you a warm glow from both being eco friendly and from the exercise!

This Solar Powered Window Alarm by Smart Solar is an easy to install system to add extra security to your home without incurring any long term running costs.

The Solar Powered Window Alarm can be placed anywhere, though obviously it is best placed somewhere to take maximum possible benefit of the daylight there. Designed to be mounted onto the window to power itself through its built in solar panels, this alarm comes with sensors that can be placed up to 60cm away from the main unit due to the adjustable wire it is attached to. The solar energy is stored in a Li-on rechargeable battery supplied.

The Window Alarm produces an alarm noise at 6.8 khz which should easily wake you up should anyone open an alarmed window and trigger it. The only concerns would be its usefulness, as if a window is broken rather than opened it should not produce a sound. Additionally, it would appear that there is no way to tell how much power is stored in the alarm or for how long the charge will run. This leads to some concerns on if it would last a whole night, especially in the long nights of winter where the daylight can also be diminished for days.

The Solar Powered Window Alarm comes as a twin pack for £24.99.

The Solar Powered Clip Watch is a concept design by Mac Funamizu. The clip watch is meant to look like a button to help it not look out of place on any outer garment or bag. The time is displayed on the screen briefly once the screen has been pressed.

The Industrial Designer Mac Funamizu felt this concept dealt with the issue of getting your hands out of your pockets, or even pulling back gloves and layers of sleeves to see the time on a normal watch. By having the watch on outer garments, like your coat, the time would just be a simple press away. Of course you will need to press the watch face to display the time, which could still get your hands cold! Many just use their mobile phone to display the time, but with the rise in popularity in touch screens, which often do not respond well to operation by gloved fingers, this clip watch could be an excellent solution.

Because the clip watch has been designed to go on the outer layers of clothes it can make use of the light around it at all times, instead of being hidden away under sleeves and such like. A solar panel is part of the screen, taking in the light and using it to power the watch, so no issues with running out of power or replacing batteries. The watch screen only displays the time for a few seconds when pressed, as this is usually all that is needed when checking the time. This helps to conserve energy while helping the illusion that the watch is just another button.

This Solar Powered Racer is a great way to educate children through play. It effectively demonstrates the abilities of solar panels in converting sunlight into electrical energy, this energy is then used to power a motor which causes the racer to race along. The Racer then shows a child how sunlight can be turned into movement.

The Solar Powered Racer has been created by Science Time as an educational toy to show how solar power can help provide the world with clean, free energy. The racer kit comes with detailed instructions for constructing the toy, which detail how the 8 parts it comes in are easily fitted together. The racer kit is suitable for children aged 8+, though this seems mainly down to the smaller parts in construction, younger children may enjoy watching the toy race once it has been constructed under adult supervision.

The Solar Powered Racer once constructed requires only light to work, this can be provided by direct sunlight or a bright indoor light bulb (though for educational purposes using sunlight would be best). This toy should provide a child with hours of enjoyment from constructing the racer to watching it work.

The solar racer is available for just £7.45 plus delivery.

This Solar Powered Bicycle Odometer features 11 different function settings allowing you to keep track of everything from current speed to fastest speed, the distance of the trip to the calories burnt on the trip. Powered by a small solar panel the odometer will last throughout any length of trip.

The Solar Powered Bicycle LCD Odometer has three buttons with which to operate it, these are SET, MODE and RESET. These allow you to keep track of an array of functions, though sometimes switching between functions with the mode button may take a while as there are 11 of them. The more notable functions are current speed, shown as SPD when on that mode, odometer (total distance) shown as mode ODO, DIS shows the trip distance, MXS shows you the maximum speed achieved, while AVS shows you the average speed achieved on the journey.

These speed settings can be viewed in either km/h or m/h (kilometers per hour or miles per hour). The odometer also has a mode to show you the time with its CLK mode, which can display the time in either a 12 hour or 24 hour format. There are settings to also show calorie consumption, to show riding time or to set an alert .

The Solar Powered Bicycle Odometer measures  7.5cm  x 5cm x 1.4cm (3in x 2in x 0.6in) making it small and compact. The odometer is also relatively light weighing only 144g and comes with all the fixtures and fittings needed to secure it onto the bicycle and allow it to operate.

Though the odometer does have a solar panel it is relatively small, but the unit can be powered from a single 3V CR2032 battery. Though the unit will gain solar power when out and in use, it may have problems at the start of a journey if the bicycle is stored indoors or under cover away from a direct light source. Alternatively the odometer could be placed in a bright spot when the bicycle is not in use.

Available for £12.74 from UxSight.

The Eolic is a wind powered generator that has been designed to be easily transported to and used in areas that do not have a steady supply of electrcity. It achieves this by being constructed to be folded up into a small and relativly lightweight bundle.

The Eolic has been designed by Marcos Madia, Sergio Ohashi and Juan Manuel Pantano to be usable in areas still under construction or being rebuilt after a desaster. It could also be used to power a small household or top up existing electrical supplies with eco friendly energy.

The Eolic can be folded up into just one package, this means there are no loose bits to go missing when it is being transported from one place to another. Constructed out of ultra light weight materials such as aluminium and carbon fiber, the generator is a portable and simple system to use. In addition, as it can be folded into a relativly small bundle it also saves on space. The Eolic can be extended up by its telescopic pole which has three section to it, to achieve a decent height to take advantage of the wind. It should take only two or three men to unfold the Eolic and get it into a functioning state.

These features mean that many of them can be transported with relative ease into areas that have a desperate need for energy, and as the wind can blow both through the day and at night the energy provided could prove to be a steady and constant help to many. The Eolic could also due to these features be a pratical way for many households to supliment their electricity needs with this eco friendly source without the difficulties other wind powered generators can cause.

The Lucet is the name given to this solar powered indoor light design. The light comprises three LED lights surrounding one battery charging area that has a solar panel on the back. The device can then be placed onto windows to charge from the sunlight during the day and illuminate the room at night. The concept is similar to the Spider Solar-Powered Light by Powerplus.

This concept, designed by Rui Palma, could be placed in groups to form a pattern on a window. In actuality many of these Lucets may be needed to provide sufficient light for them to be considered the main light source of a room, though one or two should be fine for a lower ‘mood’ light or in addition to other lighting.

The three LEDs (Light Emitting Diode) are powered from a solar panel on the reverse of the device, this energy charges the batteries which will be two AAA batteries. This may take quite some charging, as the current proposed area for the solar panel is relativly small. Fortunately LEDs require low electricity amounts to produce a strong light so the power of two batteries can be shared between all three lights without to many problems. This may mean the Lucet will not last that long into the evening and will certainly have a shortened time of  use on cloudy days when less charge is picked up due to the lower intensity of the sunlight.
