In our contribution to Enspace, The Entrepreneurship Magazine at IIT Bombay (India), Yash analyzes the sustainable business models of a number of promising start-ups in Nigeria, Mauritius, and Uganda.
These are interesting times. And entrepreneurs in particular like such times. Crucial challenges and enabling innovations exist in our markets today- [...]
Extracting, delivering, and disposing water requires energy, and similarly, many processes for extracting and refining various fuel sources and producing electricity use water. This so-called ‘water–energy nexus’, is important to understand due to increasing energy demands and decreasing freshwater supplies in many areas. This paper performs a country-level quantitative assessment of this nexus in the [...]
CAMBRIDGE, Mass. — Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays.
By dipping plain cotton cloth in a high-tech broth full of silver nanowires and carbon nanotubes, Stanford researchers have developed a new high-speed, low-cost filter that could easily be implemented to purify water in the developing world.
Instead of physically trapping bacteria as most existing filters do, the new filter lets them flow on through [...]

The best places to collect solar energy are also some of the dustiest on Earth and beyond, a quandary that leads to inefficiencies in how well the cells are able to convert strong sunlight into renewable electricity. The solution, according to new research, is to coat [...]
