The growing concern with greenhouse gas emissions and global warming can hardly have escaped anyone's attention. Being in many respects the most talked about topic of the new century, it should by now be common knowledge that humanity's reliance on fossil fuels as energy sources is gradually wrecking the ozone layer that protects the world from the less endearing powers of the sun. Yet the increasingly palpable threat of global warming and its consequences has at least resulted in a growing awareness of the problems inherent to oil-based economies. Knowledge is power, as they say, and indeed initiatives to reverse or at least slow down the ongoing climate change have multiplied several times over in the last decade or so.
Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source. The artificial leaf — a silicon solar cell with different catalytic materials bonded onto its two sides — needs no external wires or control circuits to operate. Simply placed in a container of water and exposed to sunlight, it quickly begins to generate streams of bubbles: oxygen bubbles from one side and hydrogen bubbles from the other. If placed in a container that has a barrier to separate the two sides, the two streams of bubbles can be collected and stored, and used later to deliver power: for example, by feeding them into a fuel cell that combines them once again into water while delivering an electric current. The creation of the device is described in a paper published Sept. 30 in the journal Science.
Hydrogen is the ultimate fuel because when burned it produces only heat and no carbon dioxide. The Windhunter system is a better and cleaner way to get hydrogen than the current method from natural gas. Most earth scientists are convinced that global warming is a fact and that our human activity of burning fossil fuels is the main cause. We burn coal, oil, natural gas and other hydrocarbon resources which release huge amounts of heat trapping gases into the world's atmosphere. The resulting temperature rise increases hurricane storm intensity while at the same time reduces food production.
SExpand I have written How-Tos for many of them, but I concentrate on the "why" answers, not the "how". There are lots of places on the internet with step-by-step guides.
Flexbook – Laptop Concept by Hao-Chun Huang Flexible Notebook Has Sexy Features I call myself a concept technology glutton because I can devour the most bizarre and hypothetical features, in the hope that someday we will make those advances and sexy, psycho gadgets will rule! My hope is kept alive with concepts like the Flexbook that sports key features like a flexible joint that allows you to fold and configure the laptop to become tablet or a notebook in a jiffy. Specs include a waterproof keypad, swappable rubber skins, 21:9 – 180-degree swivel touch screen that make it an eBook, tablet and notebook in one go.

Facebook sienta las bases para ser el nuevo Google Mientras el presidente de Google, Eric Schmidt, defendía el pasado miércoles ante el senado de EE UU la imparcialidad del algoritmo de su buscador, Mark Zuckerberg ultimaba el anuncio del mayor giro estratégico de Facebook desde que se lanzara en 2006. La red social, con 800 millones de usuarios en el mundo, ha dejado de ser un sitio que solo conecta a personas para pasar a ser, además, una plataforma que conecta a la gente con las cosas que recogen su actividad diaria (servicios de música, cine, periódicos...). Un cambio que, aunque pueda parecer nimio sobre el papel, deberá preocupar a Google y a Apple, porque como el famoso caballo de Troya, el anuncio de Facebook esconde armas para dar la batalla a ambos rivales. Y a cada uno donde más le duele: al buscador, en la publicidad, y a Apple, en los contenidos.
