Electricity from Urine 

Aquí hay un bonito accesorio que emplea bio-tencnología como fuente de energía: un par de calcetines integrados con células de combustible microbianas miniaturizados y alimentados con orina bombeada por los pasos del usuario ha impulsado un transmisor inalámbrico para enviar una señal a un ordenador. Este es el primer sistema auto-suficiente alimentado por un generador de energía portátil basado en la tecnología de células de combustible microbiana…

That’s the idea behind a pair of socks developed by Ioannis Ieropoulos’s team at the University of the West of England in Bristol, UK. Walking in the socks forces a bladder’s worth (roughly 648 millilitres) of urine to circulate through integrated tubes towards microbial fuels cells (MFCs), which contain bacteria that guzzle nutrients and create electricity…

Attention-sucking power

El artista francés Antoine Geiger tiene esta serie fotográfica de gente siendo absorbida por sus celulares. ¿Alguna duda de lo que significa?…

Making eye contact, a once unavoidable feat when packed into a crowded train car or museum, is now a nearly impossible mission as those around you are almost guaranteed to be sucked into their phone’s screen while scrolling through Facebook or killing digital zombies. Our increasing dependence on the information devices constantly stuck to our hands was the inspiration for artist Antoine Geiger’s series SUR-FAKE, a group of digitally altered photographs depicting random people being sucked into the screens of their phones…

Gravity Light

Este invento sí parece como traído del futuro: lámparas que generan luz eléctrica a través de la fuerza de gravedad.

Imaginen las posibilidades de aprovechar esta vieja y conocida ley física, que en nuestro planeta sobra (y tan antigua como él mismo), pero convertida en fuente de energía. Quiero ver más de esto…

It’s an innovative way of generating light and low levels of power from gravity. It takes only 3 seconds to lift the weight that powers GravityLight, creating 25 minutes of light on its descent.Benefits Can be used over and over again, anytime No need for sunshine or batteries No running costs Long lasting…

The Battle for Power on the Internet

Pensar que internet es (y siempre será) un medio libre es una idea genial, pero tan ingenua como decir que en el mundo no hay nadie a quien le interese controlar algo poderoso.
Sabemos que la realidad es otra, y lo que realmente está sucediendo – y que esta nota en “The Altlantic” describe de manera muy interesante- es una batalla donde varios frentes se han estado constantemente re-acomodando para saber que estrategia tomar, y ganar ese control que en plena era digital aun no está totalmente definido…

futuristgerd:

Distributed citizen groups and nimble hackers once had the edge. Now governments and corporations are catching up. Who will dominate in the decades ahead? We’re in the middle of an epic battle for power in cyberspace. via Pocket.

We’re in the middle of an epic battle for power in cyberspace. On one side are the traditional, organized, institutional powers such as governments and large multinational corporations. On the other are the distributed and nimble: grassroots movements, dissident groups, hackers, and criminals. Initially, the Internet empowered the second side. It gave them a place to coordinate and communicate efficiently, and made them seem unbeatable. But now, the more traditional institutional powers are winning, and winning big. How these two sides fare in the long term, and the fate of the rest of us who don’t fall into either group, is an open question—and one vitally important to the future of the Internet.

In the Internet’s early days, there was a lot of talk about its “natural laws”—how it would upend traditional power blocks, empower the masses, and spread freedom throughout the world. The international nature of the Internet circumvented national laws. Anonymity was easy. Censorship was impossible. Police were clueless about cybercrime. And bigger changes seemed inevitable. Digital cash would undermine national sovereignty. Citizen journalism would topple traditional media, corporate PR, and political parties. Easy digital copying would destroy the traditional movie and music industries. Web marketing would allow even the smallest companies to compete against corporate giants. It really would be a new world order.

This was a utopian vision, but some of it did come to pass. Internet marketing has transformed commerce. The entertainment industries have been transformed by things like MySpace and YouTube, and are now more open to outsiders. Mass media has changed dramatically, and some of the most influential people in the media have come from the blogging world. There are new ways to organize politically and run elections. Crowdfunding has made tens of thousands of projects possible to finance, and crowdsourcing made more types of projects possible. Facebook and Twitter really did help topple governments…

The Battle for Power on the Internet

walking power

Otro de esos inventos que pueden darle la vuelta otravez a la cuestión del consumo de energía (como pasó con los paneles solares y los motores eléctricos): ahora salió un dispositivo que aprovecha la energía mecánica de nuestros pies al caminar -que es mucha-, y la convierte en energía eléctrica. Según sus inventores en la Univ. de Wisconsin-Madison, las aplicaciones pueden ser muchas, comenzando por la posibilidad de cargar la pila de los celulares y otros dispositivos similares…

(Discovery News) – Basically, it means you could put a layer in the sole of a shoe – similar to the liquid-filled layers in some higher-end sneakers – and convert the mechanical energy of walking to electricity, and then transmit that to a device such as a phone. It wouldn’t replace batteries, but it would extend their lives by quite a bit. While solar power is an option for some electronics, sometimes there isn’t any sunlight, and the wattage that a small solar panel can generate is ususally enough for something like a calculator, but not a smart phone.

Krupenkin says the amount of energy humans can generate this way is quite large. A sprinter puts out nearly a kilowatt, and even walking along someone could generate about 20 watts – plenty to top up the average cell phone battery. The power could be transmitted wirelessly…
