Keeps Milk Cold When the Power Cuts Out

In rural Indian dairy villages, access to electricity is intermittent. Most people have to boil milk before they drink it, and dairy farmers face the perpetual risk of losing large batches of their product. Now Promethean Power’s new thermal battery tech offers a fascinating solution.

As Doc North explains in the video, milk can be chilled to maintain its quality without electricity, by using simple principles of heat exchange.

How technology can prevent food waste

Up to 40% of food produced in the developing world is wasted before it reaches the market, according to figures from the UN’s Food and Agriculture Organisation (FAO). With the number of middle-class consumers predicted to rise to three billion by 2030, and the majority of that growth in developing countries, tackling this problem is no small feat – particularly as rising affluence in urban areas is likely to trigger a higher demand for richer diets and more complex food supply chains.

Lack of access to cold chain technology and reliable energy sources are the major reasons for crops perishing after harvest, research by Nottingham University shows (pdf). The cost of delivering energy to remote, rural regions means that, even when storage facilities are built, they may nevertheless stand empty. Poor transport infrastructure causes further losses, and a lack of education on post-harvest practices often results in poor quality control and food being damaged during handling.
