Scraps of food could soon be helping power your home, thanks to an ultra-cheap bacteria-driven battery. Its developers hope that instead of feeding the dog or making garden compost(混合肥料), organic household waste could top up your home's electricity. Although such "microbial fuel cells"(MFCs)have been developed in the past, they have always proved extremely inefficient and expensive. Now Chris Melhuish and technologists at the U-niversity of the West of England(UWE)have come up with a simplified MFC that costs as little as ￡ 10 to make. Right now, their fuel cell runs only on sugar cubes, since these produce almost no waste when broken down, but they aim to move on to carrot power. " It has to be able to use raw materials, rather than giving it a refined fuel," says Melhuish. Inside the walkman-sized battery, a colony of E. coli bacteria produce enzymes that break down carbohydrates, releasing hydrogen atoms. The cell also contains chemicals that drive a series of redox, or reduction and oxidation reactions, stripping electrons from the hydrogen atoms and delivering them steadily to the fuel cell's anode(正极). This creates a voltage that can be used to power a circuit. To prove the MFC works, the researchers are using it to power a small light-sensitive robot. When a number of the cells are connected in series, they could power domestic appliances, running a 40-watt bulb for eight hours on about 50 grams of sugar. Earlier MFCs were inefficient because they relied on energy-hungry filters and pumps. By experimenting with different anode materials, the UWE team have figured out how to make their system work: they dump the bacteria and redox chemicals directly into the cell. In its current form, the UWE team says its organic battery can produce eight times as much power as any previous MFC. But Melhuish wants to improve this, both by scaling it up and finding a better mix of redox chemicals.

In his classic novel, The Pioneers, James Fenimore Cooper has his hero, a land developer, take his cousin on a tour of the city he is building. He describes the broad streets, rows of houses, a teeming metropolis. But his cousin looks around bewilderedly. All she sees is a forest. "Where are the beauties and improvements which you were to show me?" She asks. He's astonished she can't see them. "Where! Why everywhere," he replies. For though they are not yet built on earth, he has built them in his mind, and they are as concrete to him as if they were already constructed and finished. Cooper was illustrating a distinctly American trait, future-mindedness: the ability to see the present from the vantage point of the future: the freedom to feel unencumbered by the past and more emotionally attached to things to come. As Albert Einstein once said, "Life for the American is always becoming, never being. "

"It's that time of the year again—back to school! With the new school year just around the corner I decide it might be a good idea to collect tricks on how to wake up early for school. Whether you are a student or a happy parent, I hope your advice will work for me. Welcome you to share your own tricks on how you wake up(or help your kids wake up)early for school!" Advice 1: One of the rules I put into place for my experiment was the rule that I could not use the snooze button, ever! When you hit the snooze on your alarm you are allowing your mind to wake up gradually. This may slow down your productivity and energy... Advice 2: This smart simple tip was found in the list of 52 Proven Stress Reducers. What this tip means is that first of all you need at least two alarm clocks. You will be using one alarm clock in a usual way—for waking yourself up in the morning. But you will set another alarm clock for the time when you have to go to bed. Advice 3: There is another great self-improvement tip which some people often neglect and which you can use to advance in any area and not just to learn how to wake yourself up early in the morning. And the tip is simple: get a dog, it will help you to wake up early. Advice 4 : How to wake yourself up in the morning? Get a pet to do it? Okay, getting a pet BECAUSE you want to wake up early is a wrong thing. Do not do it. Never ever get a pet unless you love pets and unless you know you can take care of them. Pets are like kids—if you get one, you will have full responsibility for its health and life. Advice 5: We continue our quest to find the best ways on how to wake up early in the morning and do it consistently. If you search the web for "how to wake up early" or "alarm clocks" keywords combination you will definitely find Vincent Cheung's article Alarm clocks are bad and how to wake up and feel better. This article has got almost 3, 000 tips and a number of links for a reason. It includes the trick on how to wake up early that Vincent has successfully used for years and now shares with the readers of his blog.
