Electricity: Edison’s revenge | The Economist

In a few years the currently used AC power (110 or 230 Volt) will be replaced by intelligent DC power systems, based on USB connectors. This means that each and every building has to be rewired, outlets needs to be replaced and all the electronic equipment needs to be equiped with direct DC circuits. But the advantage is that every device can now take current when its needed, and as much as needed. And an intelligent micro-grid system is created. Levering available current to those devices that it need at moments its needed. No more wasting power by transformers, and overbooking the used Amperes, blowing up fusions.

This would be great!

The Story of Electronics, releasing Tuesday, NOVEMBER 9, employs the Story of Stuff style to explore the high-tech revolution’s collateral damage—25 million tons of e-waste and counting, poisoned workers and a public left holding the bill. Host Annie Leonard takes viewers from the mines and factories where our gadgets begin to the horrific backyard recycling shops in China where many end up. The film concludes with a call for a green ‘race to the top’ where designers compete to make long-lasting, toxic-free products that are fully and easily recyclable.

Rethinking Progress

Rethinking Progress is de basis film van de Ellen MacArthur Foundation. In samenwerking met het One Planet Architecture institute (OPAi) is een Nederlands ondertitelde versie gemaakt.

Dit filmpje geeft de essentie aan van de circulaire economy, het cradle-to-cradle principe. En het mag duidelijk zijn dat ik daar een groot voorstander van ben!

De circulaire economie is het verbinden van alles!
