Great energy inventions

In the 1990’s Trevor Baylis a British inventor saw a TV program about the spread of AIDS in Africa. One of the ways to prevent the spread of AIDs and other diseases is through education and information using radio broadcasts. The dissemination of information over the airways requires the target audience to have radios. At the time, most radios needed mains power or batteries. Baylis recognised that access to electric would be a massive challenge and that another solution would be needed. baygen

Baylis immediately set to work and invented the first wind up radio which enabled the radio to be charged up by an internal dynamo operated by a hand crank.  He eventually went on to form Freeplay energy which is still operating today and still innovating new products.

In addition to radio receivers, Freeplay also produce a wide range of other products which are well suited to remote settings where electricity remains a challenge. The original wind up technology has been refined over the years and is more efficient. Freeplay has incorporated solar technology into their solutions which means that radios can be powered throughout the day without any need to turn the handle! I am pleased they have retained the concept as radios can still be used if they run out of charge during the night.

Over the years, I have seen similar products from other manufactures, but during a recent evaluations of Freeplay products, I was impressed by the quality of build. For remote locations, any technology must be built strong enough to withstand the harsh conditions and be reliable. This is really important as once the technology is shipped, it’s not easy to fly it back to the factory for a replacement.

 In this article, we will explore some of the Freeplay product and discover how they can add a lot of value to communities which are remote or affected by a crisis.

As an organization, Freeplay manufactures small portable products for families. The technology is targeted at a number of markets such as emergency preparedness, aid & development and any consumer who engages in outdoor activities such as camping.

Encore Radio
encoreThis radio is well suited for use in developing nations. The radio has been cleverly designed so that it can receive longer range broadcasts over two SW bands. For local broadcasts, the radio can receive AM and FM. I was also impressed with the built in recording function which allows the radio to record broadcasts and save them to memory cards in MP3 format via the built in card reader.

In addition to recording programs in MP3 format, these radios can be used in schools as a tool to enhance education. Any MP3 content can be played. Up to 125 audio books can be stored on a 32GB SD card!

Power for the radio and its two inbuilt bright LED lights are charged up from the crank handle at the rear or the small solar panel on the top. (A larger external solar panel is also included).

This is not the only radio made by Freeplay, there are others available which are designed for different uses such as emergency preparedness.

Energy Hub
hub
The Energy Hub is a small solar system designed for a small household. The kit comes with a controller and two lights (as pictured). An external solar panel can charge the battery up in 6 hours to full capacity. On a full charge, two bulbs on high setting will run for 8 hours. A single bulb on 50% setting will run for 32 hours.

The cables for the lights and panel are sufficiently long enough to allow for permanent installation in a small family hut.

LanternReliance Lantern
Over the years, I have seen a number of lanterns but this one really impresses me not just for the build quality, but for the overall design. Its built to withstand weather and shock and can provide light up to 45 hours on a single charge. It also has a built in Siren which is really useful in some applications.

The Lantern Library:  Good technology can cost money, and I have heard of innovative projects such as “Lantern Libraries” where lanterns are held by schools and kept charged up. The idea is for pupils to borrow a lantern from school (sometimes for a small cost recovery fee) to take home. In darkness, the pupil has a light to see their way home, and at home, the pupil can study using the light. The addition of the built-in alarm just makes the whole concept better as a child can activate it if he/she is attached.

Conclusion.
Freeplay’s original concept to connect communities to broadcasters is just as relevant today as it was back in the 1990s when Trevor Baylis launched his first wind up products. In the Aid and Development sector, mobile phone networks are used by the UN and NGOs to interact with communities. Whether it’s a cash voucher system, SMS reminders for appointments at clinics or community engagement via collection of feedback over SMS, mobile phones are needed and they need to be charged. This requirement has not escaped Freeplay as in the three technologies we reviewed, all of them have built in sockets and supplied with the appropriate adaptors to charge up most mobile phones and other USB devices.
