Coolar — an electricity-independent medical refrigerator

Living off the grid, without access to stable electricity, carries consequences beyond simply not being able to switch on the lights at night. In hospitals and clinics across developing regions, the inability to rely on electricity — or a complete lack thereof — translates into profound shortcomings in the provision of life-saving treatments. William Steel interviewed Julia Römer for Cleanleap, Julia co-founded Coolar in 2014, with the goal to develop a better solution for off-grid refrigeration of medical supplies.

A Look at Emerging Drone Delivery Medical Services

That UAVs can fly brings immediate advantages in terms of how they may travel, and the locations they can reach — often surpassing what’s possible with conventional means of transport. Meanwhile, refinements in computer systems has led to advanced navigation and control systems being embedded within UAV systems — a development that’s been crucial in enabling UAV services to function effectively. With improvements in performance, even consumer grade UAVs are able to carry and deliver small packages over considerable distances.

Making body soap from recycled oil in Cameroon

Municipalities in developing countries are increasingly producing solid and liquid wastes. The management of those waste are relevant because of their impact to the environment and health. For instance, disposing waste in surrounding areas become vectors for the development of diseases, and they contribute to produce lixiviates which are already infiltrating into the water table. In addition, solid waste accounts for 5% of the total GHG emission. This becomes an environmental issue that has to be resolved.

Recovering energy from waste can power Africa

Production of electricity from waste has the potential of providing up to 83.8 TeraWatt hours, which is about 20% of the electricity needed in Africa by 2025. This is according to a study co-authored by the European Commission Joint Research Centre. However, this requires stringent waste management policies to be put in place, and today Africa lacks the adequate infrastructure needed to install these environmentally friendly methods.

'Liters of light' shining in Cameroon slums

A common characteristic of informal settlements in Cameroon is the lack of indoor lighting during the day. To carry out any productive activities, households have to turn on the lights – for those who can afford electricity - or use kerosene lamps or candles adding to their electricity consumption and accompanying energy-related expenses as well as indoor air pollution. This gadget is an innovative passive lighting technology based on a transparent plastic bottle filled with clean water. It is fitted into the corrugated iron roofs of houses without ceilings.

Do large dams still fit in the sub-Sahara energy and water agenda?

Huge dams have been touted as effective in providing drinking and irrigation water, all cheaply and sustainably. Recent studies reveal otherwise as most of these projects in sub-Sahara turn out to be more costly than planned. A recent study has quantified claims that large dams also lead to more malaria being spread in the sub-Saharan, thus adding more weight to concerns on whether these projects should be pursued actively in favor of the alternatives.
