Solar gadgets

These 9 solar gadgets can save you in the middle of nowhere!

We have all experienced situations we were so hard up for our electrical gadgets but they were going to run out of battery or we didn’t have access to power grid. In this article we intend to talk about a solution for this problem which is using gadgets charged by sunlight called “solar gadgets” which can be really helpful in these situations.

1- cell phone solar battery charger

Imagine you are on a trip and your cell phone runs out of battery, SO UNLUCKY! what if you need an emergency phone call exactly at that horrible situation ? Don’t worry, here’s the solution, you can always have an external battery which can be easily charged by sunlight. These rechargeable Li-ion batteries are available in wide range of capacities and also compatible with USB-based devices.

Remember the above situation, in case you don’t have an extra battery, you can recharge your phone using this window-mounted solar battery charger. In fact it’s a small-scale photovoltaic cell absorbing sunlight and generating enough current to charge a phone battery.

2-Solar Cap-mounted LED Lights

Your desk isn’t the only place you can enjoy reading books, articles or newspaper. Sometimes you need to read a map, the only thing showing you the way out of an unknown mysterious jungle at night, so a gadget lighting the map and making in readable can be life-saving.

As you see in the picture, this type of products can also be used by fire rescue or more general any rescue search team or cave explorers who need lights to inspect surfaces not to fall down and also keep wild animals far from themselves. The lights can be charged by sunlight (the upper surface is covered with solar cells) and batteries both.

3- Solar Fire starter

Nowadays people use flashlights in SOS mode as a tool for asking for help when they are lost , but the conventional method was releasing some smoke so others could understand where they were. We all know running out of batteries is a common problem in all electrical gadgets, so there should always be a second alternative. Yeah! Getting back to ancient times is the solution! SMOKE!

With this solar fire starter you can easily start a fire on dry leaves or waste papers to release some smoke. It focuses sun energy to a precise focal point in which temperature reaches about hundred degrees.

4-Solar Traffic Signs

Many people lose their lives every year in car accidents all over the world and the main reason for some of them is ignoring the traffic rules. But some of them aren’t careless people; they just don’t see the traffic signs at night especially on dark roads. Using LED lights in traffic signs attracts drivers’ attention so fewer accidents will happen and more lives will be saved annually. The lights are charged via their solar cells when exposed to sunlight and LEDs are off in this time of day and they get on at nights.

Similarly traffic lights can also be another beneficial application of solar charged LEDs as the power plant and the consumer are both in the same location (on the traffic light) so cabling is reduced to some meters instead of kilometers which directly affects installation costs. These systems function even in blackouts or any faults in the grid which might result in traffic lights malfunction and this feature prevents chaos situation and car accidents.

5- Solar Hearing-aids

Some new technologies directly relates to life. You might have seen some viral video clips on the net in which people experience hearing after years of being almost deaf, their feel of joy is perfect. So we can understand how miserable someone feels when their hearing-aids have run out of battery.

Solar hearing-aids can be easily recharged by their solar chargers in just some moments due to the fact that hearing-aids consume low energy in scale of mili-Ampers. Life-saving gadget is not only one which saves our life in emergency situations, but even those which help us experience a better life.

6-Solar Generators

Solar generators consist of a portable panel and a box with built-in DC/AC inverter and battery. Actually it’s the most useful electrical gadget you must always have when going somewhere like a camping , jungles or dessert , in general anywhere far from the power grid.

In fact engineers have compacted the power plant, transmission lines and distribution grid all in a box and a solar panel called solar generator. The power is generated by solar panels and then transmitted to the box via cables, stored in batteries and then inverted into AC waveform by built-in inverter. As you can see in the picture different outlets are designed so you can easily charge any electrical gadget such as phones, tablets, digital cameras, lights, etc. The reason to call this a life-saving gadget can be similar to flashlights and battery chargers which were discussed before.

7- Smart Solar Pill Bottle

Forgetting the right time to take pills is a great concern for the elder generation. This might be an important threat for people with major health problems who need to take regular medications on exact times for example people suffering from Diabetes.

Solar smart pill bottles can remind you when to take your pills once they are set on a specific time. The reminder will ring in pre-set time intervals, twice a day for instance. There are also some sensors in the bottle assessing the number of pills in the bottle, and can send messages or warn the patient by special alarms. The power needed for all this actions is provided by solar cells designed on this bottle. It’s really a great idea using sunlight as power resource for this gadget because the amount of power required is really few and can even be achieved with low level of light.

8-Solar Bag Water Purifier

About 3.6 million people – 1.5 million children included mostly from poor African countries – are estimated to pass away annually because of water-related diseases such as diarrhea, cholera and dysentery. That’s why scientists began some experiments on purifying water with materials and resources easily accessible by majority of people. The experiments resulted in these solar water purifiers, and some other chemical models of purifiers.

These bags are nowadays widely used by not only Africans, but mission teams, disaster relief and even exploratory groups where drinking water is not available. They are produced in different sizes, and can purify at least 3.5 Liters in each process. The general mechanism is collecting water into a bin, as the water is vaporized by sunlight which raises the internal temperature of bag, contaminants are left behind when condensed water is collected in a pure water bin from which we can then drink clean water.

9-Solar Bike Lock

Nobody has ever lost his life just because a thief stole their bike, so why could a bike lock be life-saving?

This lock-called gadget is not a lock in fact; it’s just locked to the bike or even motorbike. Thanks to the microchips technology, a sensor, power generation part, communication and locating systems are all integrated in this tiny pocket-size gadget. In case an accident happens, the sensors detect severe strokes, microchips send messages to pre-set contacts and medical SOS team and also your location for them so they can find you ASAP. The power required for all these actions is generated by solar cells on the lock.

There are hundreds of new ideas which are involved with solar power solutions. these kind of devices can save us in situations that we don’t have any access to electricity. In this article we tried to show you some of these innovation, if you liked these ideas, support these kind of gadgets and try to buy some of them to help develop this green culture and save the planet.
