Solar-powered school bags changing Cote d’Ivoire’s education

“No child should study in the dark”: Solar-powered school bags changing Cote d’Ivoire’s education
By  on November 1, 2018 — Evariste Akoumian, a 37-year-old Ivorian, invented the “Solarpak”, a schoolbag with a solar panel and a lamp, to improve the education of young schoolchildren from rural, non-electrified areas. Using the lamp, children can now comfortably study after dark.

Didi plans charging stations for electric vehicles

China is kicking America’s butt. They have five and ten year plans to do stuff. What plans do we have? USA better get on the ball and stop laying on yesterday. The world is not waiting for us anymore.

Ride-hailing giant Didi Chuxing on Thursday announced a new joint venture to roll out charging networks for electric vehicles, aimed at attaining a firm foothold in the country’s booming new energy car market.

‘Human power plant’: How the cell’s molecular machines work

Every cell in our body is like a workshop full of machines. The machines are embedded in mitochondrial membranes – microscopic energy centers. They serve to synthesize ATP (adenosine triphosphate) – sort of a fuel for humans that our whole body uses in order to function properly.

The death of the internal combustion engine

“HUMAN inventiveness…has still not found a mechanical process to replace horses as the propulsion for vehicles,” lamented Le Petit Journal, a French newspaper, in December 1893. Its answer was to organise the Paris-Rouen race for horseless carriages, held the following July. The 102 entrants included vehicles powered by steam, petrol, electricity, compressed air and hydraulics. Only 21 qualified for the 126km (78-mile) race, which attracted huge crowds. The clear winner was the internal combustion engine. Over the next century it would go on to power industry and change the world.

But its days are numbered. Rapid gains in battery technology favour electric motors instead (see Briefing). In Paris in 1894 not a single electric car made it to the starting line, partly because they needed battery-replacement stations every 30km or so. Today’s electric cars, powered by lithium-ion batteries, can do much better. The Chevy Bolt has a range of 383km; Tesla fans recently drove a Model S more than 1,000km on a single charge.

It’s Too Bad Electric Scooters Are So Lame, Because They May Be the Future

THE FIRST THING you need to know about scooters is that it’s impossible to look cool riding one. When you ride one, people look at you with disdain. They shout things like, “you’re the problem!” and “get off the sidewalk!” (Seriously.) They try to get in your way as much as possible. Even people on hoverboards and electric skateboards judge you. These are just facts.

N. Korea defiance challenges moral authority of nuclear club

north Korea H bomb

Developing a credible nuclear force is in the long run cheaper for Pyongyang and far more likely to be successful than building and maintaining the massive and highly sophisticated conventional forces that would be needed to deter the United States. Though mega weapons like the H-bomb have become largely irrelevant to superpower military planners, who now have the technology to conduct precision attacks that are far more effective and less likely to generate universal condemnation, it’s the kind of threat that still works for Pyongyang.
