OLPC experiments with cow-powered laptops (seriously)

Filed under
OLPC

The One Laptop Per Child Project (OLPC) is toying with a novel source of power for its low-cost XO laptops: cows.

"We plan to drive a dynamo (taken from an old Fiat) through a system of belts and pulleys using cows/cattle," wrote OLPC's Arjun Sarwal, in an e-mail dated Oct. 21 and posted to one of the group's discussion lists.

Sarwal and others are now finalizing the design of the cow-powered generator.

The goal is to develop a low-cost energy source that can be used in Indian villages. Working in a village close to Mumbai, Sarwal said the group considered using solar energy but sunlight near Mumbai was not "consistently strong." There was not enough wind or running water nearby to use these as sources of power, and the cost of running a gas-powered motor was too high.

An introduction to Joplin, an open source Evernote alternative

Joplin is an open source cross-platform note-taking and to-do application. It can handle a large number of notes, organized into notebooks, and can synchronize them across multiple devices. The notes can be edited in Markdown, either from within the app or with your own text editor, and each application has an option to render Markdown with formatting, images, URLs, and more. Any number of files, such as images and PDFs, can be attached to a note, and notes can also be tagged. I started developing Joplin when Evernote changed its pricing model and because I wanted my 4,000+ notes to be stored in a more open format, free of any proprietary solution. To that end, I have developed three Joplin applications, all under the MIT License: for desktop (Windows, MacOS, and Linux), for mobile (Android and iOS), and for the terminal (Windows, MacOS, and Linux). All the applications have similar user interfaces and can synchronize with each other. They are based on open standards and technologies including SQLite and JavaScript for the backend, and Terminal Kit (Node.js), Electron, and React Native for the three front ends. Read more
