Hand Crank Dynamo Bag

Hand crank dynamo bag with a LED foldable lamp, detachable solar panel and a plug-in charging port

What is it?

It is an object, a school bag that can be very useful in evening study for millions of pupils not privileged to access electricity in their homes hence improving the pupils learning capability in the evening. It is simple to use and has a hand crank dynamo, an attached foldable lamp, detachable solar panel and a plug-in recharging port. It can be recharged by cranking/winding the dynamo, or by use of a detachable solar panel. It also has a provision of power plug-in port which can be plugged into a multiple adapter charger at school.

How is it used?

The bag is used by placing it on a flat surface like on a table or even by hanging it on a wall by use of a hook near the user. It is unfolded and lit using On-Off switch. The bag is recharged by use of a detachable photovoltaic panel, by cranking or even by recharging it at school by use multiple adapter charger.

What technologies does it incorporate?

It incorporates various technologies like use of detachable photovoltaic/ solar panel to capture free clean energy from the sun during day time which is later used at night for study, detachable hand crank dynamo which can be used to substitute or even augment the solar panel can also be used. The bag has an extra charging system which can be used to charge the bag at school using a multi-socket charger which can charge multiple bags at the same time.

How does it work?

This is a school bag with a light plug-in rechargeable study lamp. The electric power charge from the school charging unit can be used for study in the evening by the pupil. It has an additional winding/cranking charging system and a small solar (photovoltaic) panel to supplement the plug-in charging in case of main grid power failures or even when the school has no power supply. The bag is made of durable tough canvas fused with a water proof liner. This is to protect the lamp’s electrical components, books and even the tablet/ laptop in case of rains. It has a pocket made of soft material which can accommodate a tablet/ laptop preventing it from direct impact/shock in case the bag falls down. The bag’s lamp is made from light emitting diodes (LED) which consumes very minimal power. The bag’s battery and charging system has an optional serialized lock with a secret password which should either be kept by the teacher, parent or guardian for limited access from the pupil/any other unauthorized person who may damage or vandalize the battery and its charging system.

Who uses it?

The bag can be useful by millions of pupils in the world not privileged to access electricity in their homes bringing them in a fair learning competition platform with those who can access clean energy for learning. It will improve learning capability in the evening. This will be achieved by recharging the bag’s battery system.

Why does it help?

It helps because it is able to enable learning in the evening continue even when the pupil is not connected to grid electricity or any other form of energy. It will also enable pastoral communities who move from one region to other (e.g. Maasai, Turkana, Pokot, Saburu, Borana communities in Kenya) to access to clean renewable energy just like other non-pastoral communities, this will bridge the gap between those who can access clean energy and those marginalized communities.
It solves the problem of lack of clean energy for studying in the evening by proving a solution to a major existing problem by providing its solution.
Due to the security challenges facing some countries in the world e.g. terrorism, child rape, child abductions, and other forms of child abuse, which happens mostly when the pupils are on the way home and especially in the evening, will significantly reduce since the pupils will be able to get home before darkness sets in and still finish their assignments at home even if there is no electricity in their homes. Parents will be relieved the burden of buying kerosene for evening study for their kids and instead save the money. Use of kerosene poses many health risks like eye and respiratory conditions among others.
