A portable solar fridge for delivering vaccines to rural communities

Spotted: The World Health Organization estimates that 1.5 million deaths are caused by vaccine-preventable diseases every year and one, if not the main, obstacle to improving essential vaccine distribution is a lack of refrigerated storage. Now, a portable, solar-powered cool box is helping healthcare workers across Kenya improve vaccination rates for some of the most common diseases. 

Engineer Norah Magero created the VacciBox as part of her work as co-founder and CEO of Drop Access, a Kenya-based organisation supporting off-grid communities in becoming sustainable via renewable energy solutions. Drop Access helps small communities access financing for solar energy projects, trains farmers to use new sustainable agricultural methods, and makes it possible for healthcare teams to safely store and transport vaccines and medicines. Having initially outsourced manufacturing to China, Magero and her VacciBox co-founder James Mulatya knew that the cost of the refrigerator was important to expand vaccine access, so decided to work with other local engineers to keep production in the country. 

Solar-powered and with a built-in battery backup, VacciBox uses the Internet of Things (IoT) feature to track temperatures, location, and maintenance needs for each refrigerator. Designed explicitly to be easy to transport on the back of a bicycle or moped, the fridge comes with a pop-up handle, rubber wheels, and a USB charging port as an additional service.  

Currently in use in two pilot locations, immunisation at one of the facilities has already increased by 45 per cent with the help of the VacciBox. The design won the 2022 Cisco Global Problem Solver Challenge Grand Prize, and Magero plans to use the $250,000 (around €234,000) prize to expand production and expand into other countries.  

The challenges of keeping medicines appropriately cool are sizeable, and Springwise has spotted innovations seeking ways to tackle this problem by creating medicines that are stable at room temperature, such as immunisations that are administered via a patch, or vaccines encased and protected in silica.

A portable EV charger to eliminate range anxiety

Spotted: One fear for many electric vehicle (EV) owners is the thought of running out of juice miles from the nearest plug. Now, startup ZipCharge is poised to eliminate range anxiety with its ZipCharge Go portable charger. The company describes the Go as a ‘flexible and convenient charging solution’ for those without easy access to fixed charging points.

The portable powerbank was introduced at last years’ COP26 summit, and is about the size of a large suitcase. It weighs around 50 pounds, but is equipped with wheels and a handle, for greater portability. The idea is that users charge the Go from a household socket at a lower cost than using a public charger, then wheel it to where their car is parked. Once the Go’s power cable is locked into the car’s charging port, the device is secure, and its recycled plastic shell allows it to be used in all weather.

The ZipCharge Go can charge from any socket, and comes with a Type 2 EV socket. A 4-kilowatt-hour version will provide up to 20 miles of range after 20 minutes, and a higher capacity, 8 kilowatt-hour version will be able to provide around 40 miles of range. ZipCharge suggests this is enough for the average daily commute. The device can be charged up at home using an app, that allows users to schedule charging for off-peak hours, when electricity is cheapest.

According to a study by Ofgem, a lack of charging options at or near to home is a major factor in whether buyers decide to opt for an EV. A number of areas in the UK are installing charging points in streetlight poles or on streets, but these are often more expensive to use than home charging. The ZipCharge Go could help address those concerns. As the company says, “The best way to charge an EV is when you don’t need to. Top-up charge wherever you park, to avoid the visit to the charging station.”

As EVs become more popular, a number of innovators have turned to the issue of making charging more convenient. Some ideas covered here at Springwise include charging stations designed to include a range of amenities and AI-powered smart chargers designed to reduce the carbon footprint of charging.
