flea market
什么是flea market呢?Flea market实际上和跳蚤一点关系都没有。Flea
market是一种往往在周末举行的非正式集市,flea
market一般都是在户外,而且那儿有许多摊贩出售各种各样的东西,有不少都是用过的旧东西,新的东西也有,但是质量一般都比较差,价钱也很便宜。可是,要是你眼光敏锐的话,你能花很少的钱买到很有价值的古董和其他东西,就像下面这个人一样:
例句-1: I was lucky when I went to the flea market today. In the
middle of all the worthless junk I found a carved jade Chinese
snuff bottle and bought it for five dollars: the seller didn't know
what it was.

15、带可旋转调速轮的汽车
许多使用调速轮的交通工具在刹车时可以存储能量,在加速行驶时可再利用,从而减少了加速时所需的燃料。然而装配这种调速轮的汽车通常都是体积较大、较笨重的。英国西尔维斯通郡“飞鸟系统”公司现已设计了一种体积较小、重量很轻的碳纤维制成的调速轮,它的旋转速度是常规调速轮的3倍。据称,这种新型调速轮能使汽车减少耗油量20%左右。
技术研发地:英国西尔维斯通郡,该技术处于研发阶段。
16、不采用铂作为催化剂的燃料电池
与一部使用内燃机的汽车相比,装配氢燃料电池的汽车每年可减少2.4吨二氧化碳的排放量。然而这一技术实现时的最大困难在于每部汽车氢燃料电池设计上需要价值2000美元的铂催化剂。英国东英吉利大学的查尔斯-皮克特(Chris Pickett)表示,从铁和硫原子中提取合成氢化酶物质可以取代铂作为催化剂。铁是一种非常廉价的金属,其价值仅为相当重量铂的千分之一,这将意味着能够制造出更廉价的燃料电池。
技术研发地:英国,该技术处于研发阶段。
17、汽车就是一个电池
采用可充电电池组的电动汽车会逐渐耗完电池组的电解液,但目前一些最新设计的电池是传统汽车电池的4倍电容量。在市区内行驶的电动汽车可一次充电行驶30-50公里,而这种新一代电池的汽车却能够达到一次充电行驶160公里。采用新电池的电动汽车不必存储在车库中,当供给超过需求时,该静止状态的电动汽车能够从再生能源中存储能量;当电能需求超出供给时,存储的电能将释放至输电线路上。据悉,这项技术是由多个研究机构共同完成的,其中包括:澳大利亚珀斯市科庭科技大学、美国特拉华州立大学等。
技术研发地:美国和澳大利亚,该技术处于研发阶段。
18、空闲状态节能的发动机
当发动机处于空闲状态时,它仍耗费大量的燃料,在美国长途卡车虽然处于停动驱动状态,但其发动机仍延长运行8小时。火车头72%的时间都是处于空闲状态,仅在美国,由于发动机在工作空闲阶段仍耗量工作将每年使40亿升燃油浪费,并释放出1100万吨的二氧化碳。目前,研究人员采用一系列的可实现技术能够有效地降低发动机空闲状态运行的问题,其解决的方案包括:在公路边的廉价餐馆和自动化系统设立电气化停车位,基于当前的温度和其他条件,将发动机关闭。这项技术将节能90%。
技术研发地:美国,该技术现已推广。
19、远离海岸的直轴风力发电涡轮机
远离海岸更强、更稳定的风力意味着每个风力涡轮机可产生比海岸风力涡轮机多30-50%的电能,由英国克兰菲尔德郡风力公司研制的风力发电涡轮机可沿着垂直轴进行漂浮,尤其适合于低重力中心和对风向较敏感的远离海岸水域发电操作。这意味着能够制造比水平轴涡轮机更大的风力发电装置,据悉,水平轴涡轮机超过一定的高度下会变得不稳定,降低工作效率。目前设计的远离海岸的垂直轴风力发电涡轮机比较便宜,且比传统涡轮机更易维持,这是由于其装置主要定位于海平面上。
技术研发地:英国克兰菲尔德郡,该技术处于研发阶段。
20、沙漠水分诱捕器
非洲纳米比沙漠每年仅有10毫米的降雨量,目前科学家从纳米比沙漠中生活的一种甲虫身上获得了灵感,英国伦敦国家历史博物馆的安德鲁-帕克(Andrew Parker)最新发明了一种方法能够诱捕空气中的湿气水分。在英国工程公司Qinetiq的工程师的帮助下,他基于一种甲虫背部可将水分引导进入嘴中的亲水和厌水肿块的特性,设计了一种类似该原理的特殊物质。帕克和同事们希望将该物质放置在雾中,便于在沙漠地区捕获到饮用水和灌溉用水。这一设计要比之前曾使用过的传统网状水份收集器的效率高10倍。
技术研发地:英国,该技术处于研发阶段。
Some vehicles use flywheels to store energy from braking and reuse it during acceleration, cutting the fuel required to accelerate. However, these devices tend to be large and heavy. Flybrid Systems, based in Silverstone, UK, has designed a smaller, lighter flywheel that uses carbon fibre and spins at over three times the speed of conventional flywheels. This should make the Flybrid system cheaper and easier to fit into vehicles. Flybrid is now developing a system for a Jaguar saloon car which it predicts should cut fuel consumption by around 20 per cent.
UK: under development
Compared to a car with an internal combustion engine, one powered by a hydrogen fuel cell could save 2.4 tonnes of CO2 emissions per year. The snag is that conventional fuel cell designs require around $2000 worth of platinum catalyst per car. Chris Pickett at the University of East Anglia in Norwich, UK, suggests making synthetic versions of the enzyme hydrogenase out of iron and sulphur atoms to take platinum's place as a catalyst. Iron is one-thousandth the price of platinum weight for weight, meaning a much cheaper fuel cell.
UK: under development
Electric cars run off the juice in their rechargeable batteries but some batteries can store up to four times the electricity that the typical owner actually uses. The typical urban range of a car is around 30 to 50 kilometres per day, yet the new generation of electric cars have batteries with the capacity to store 160 km per charge. Instead of sitting idle in garages across the world, stationary electric cars could store energy from renewable sources when supply exceeds demand. This stored energy could then be released to the grid when the demand outstrips supply. The idea is being pushed by several research groups, including Curtin University of Technology in Perth, Western Australia and the University of Delaware, Newark.
US, Australia: under development
Big engines burn a lot of fuel when they are left to idle. In the US, long-haul trucks run their engines for 8-hour stretches while their drivers sleep. Train yard locomotives spend as much as 72 per cent of their time idling. In the US alone, that adds up to 4 billion litres of wasted diesel fuel and 11 million tonnes of CO2 emissions per year. New, readily available technologies, including electrified parking spaces at truck stops and automated systems that turn engines off and on based on temperature and other conditions, can reduce these impacts by 90 per cent.

21、室内电器耗电远程监控器
澳大利亚最新技术可实现当人们离开家时能够杜绝任何电器的损耗电能现象,由墨尔本市闪米特科技发明公司研制一种智能控制器可让用户通过软件监控和关闭室内所有家电,而这个软件可能下载到用户的手机或者便携式电脑中。该公司的初步研究显示,一座办公大楼启动该节能措施,将每年降低耗电量25%。
技术研发地:澳大利亚,该技术现已推广。
22、从鸡毛中提取纤维
每年有3800万吨尼龙和聚酯纤维等合成纤维的生产来自石化产品。目前基于澳大利亚最新技术,可以部分地将合成纤维产品从肉禽市场上所废弃的500万吨鸡毛中提取。澳大利亚季隆市科学协会和研究组织的安德鲁-普尔(Andrew Poole)负责该项研究,他和研究小组同事发现从废弃的鸡毛的坚韧化学抗性角蛋白质中可以提取纤维。
技术研发地:澳大利亚,该技术处于初级研发阶段。
23、“海水温室”
包括北非和其他沿海地区都面临着缺少淡水的危机,即使该地区被海洋所环抱。英国一家叫做“海水温室”的公司正在开发三个项目,计划使用太阳能从海水中提取淡水资源,该公司将太阳能发电站和温室进行了整合设计,可浓缩太阳能的热量蒸发海水。这些蒸发处理过的海水可用于农作物灌溉。
技术研发地:英国,该技术现已推广。
24、面部识别摄像头
网络摄像头能使能量消耗监控软件工作得更好,目前设计了许多程序可以帮助计算机减少电能消耗,并且使电脑处于睡眠状态时键盘和鼠标无法使用。但是这些节能软件会使得当用户试着阅读和观看视频时,计算机屏幕会变暗。研究人员最新设计了一种方法,运用面部识别软件连接网络摄像头,这能使电源节能管理更加有效,可实现只有当没有人注视显示屏时计算机才会进入休眠状态,而不是经过所设置的一段时间才进入休眠。这项技术每年能够节约台式计算机80%的电能。
技术研发地:英国设菲尔德市,该技术现已推广。
25、金属纳米微粒用于地热能量开采
在水中增加金属纳米微粒用于地热能开发,可在全球范围内用于更多的可循环能量生产制造。按照传统方法,地热能发电站需要160摄氏度以上的地热能,遗憾的是,世界上仅有少数地区的地热能可以达到这一高温,而且必须开采至地下5公里以下。一些增强地热系统仅有65摄氏度,而且利用效率并不高,因此地热开发成本非常昂贵。在水中添加金属纳米微粒可以进一步增加地热开发进程,在相同的液体地热水中可增获30%热能,美国华盛顿太平洋西北国家实验室人员计划今年底进行一项地热开采研究。
技术研发地:美国,该技术正处于研发阶段。
26、新一代智能调节冰箱
英国科学家正在研制新一代智能冰箱,通过调节电能的供给和需求对比分析,可更加缓和电能的突然上升和降低。英国伦敦RLtec公司正在研发的技术可使冰箱基于动态的电能供给和需求量,预先调节电能的过剩和补给,从而避免了当供电非常低的状态下,冰箱需电量处于最大值。RLtec公司评估这项技术每年可降低英国200万吨二氧化碳排放量。
技术研发地:英国,该技术正处于研发阶段。
27、“地砖”可耗能同时制造电能
当人们使用能量每一个过程中,为什么不考虑同时恢复能量呢?美国PowerLeap公司现最新研制压电材料制造一种特殊的“地砖”,当电量消耗的同时,这种特殊地砖可以产生电能。据该公司评估分析,像安装在耗电量较大的火车站,每100平方米区域每年将产生18250千瓦/小时的电能。
技术研发地:美国,该技术正处于研发阶段。
28、将计算机服务器放在海洋中
一个大型计算机数据中心需要大约3万个家庭所需要的电能维持,目前科学家提出了一种新的革新方法,很大程度地削减了计算机数据中心所需的电能。美国加利福尼亚州立大学圣迭亚哥分校网络系统中心主管阿米-瓦达特(Amin
Vahdat)称,在海洋上以式样新颖的货船或者特殊设计的船只装载着计算机服务器,能够减少一半的计算机维持能量。利用海水温度可对计算机服务器进行冷却,而不用机械式降温风扇等装置,同时也可以使用波浪作为一种清洁能量。目前,全球已有多家公司利用于研究这项技术的可行性,但瓦达特评估称,在该计算机服务器系统在海洋环境中适用之前,至少需要3-5年时间。
技术研发地:美国,至今尚未应用。
29、太阳能蓄热器
只要太阳照射,太阳能就能持续产生,但是输电网络无法在夜晚持续产生太阳能。然而,科学家最新研制的一个17兆瓦太阳能发电站可以夜以继日地提供稳定的电能。目前,这个被称为“吉姆太阳能计划”太阳能蓄热器建造在西班牙Seville地区,它将是第一个商用发电站,使用熔盐吸收来自太阳的热能,能够存储热量持续15个小时。该装置可用于产生驱动涡轮机产生电能。
技术研发地:西班牙,该技术现已推广。
Now there's no excuse to leave any electrical appliance running when you leave home. A new smart controller developed by Semitech Innovations in Melbourne, Australia, lets you monitor and switch off all your household appliances via software downloaded onto your mobile phone or laptop. One pilot study by the company showed that an office building was able to cut its energy consumption by 25 per cent.

Every year 38 million tonnes of synthetic fibre such as nylon and polyester are produced from petrochemicals. These, in part, could be replaced by fibres made from the 5 million tonnes of chicken feathers left over by the meat industry every year, says Andrew Poole at the Commonwealth Scientific and Research Organisation in Geelong, Australia. His team has made fibres out of the tough chemical-resistant protein keratin found in waste feathers.

Arid coastal regions, including most of north Africa and other coastal subtropical regions, have severe water shortages and yet are surrounded by the sea. Seawater Greenhouse, a London-based company, is now piloting three projects to economically extract fresh water from the sea using solar power. The company builds greenhouses with integrated solar plants that concentrate the sun's heat to evaporate seawater at one end of the greenhouse. The vapour condenses at the opposite, cooler end and this pure water can then be used for irrigation.

Webcams can make energy-management software work better. Most programs designed to help PCs draw less power are based on putting the computer into sleep mode when the keyboard and mouse aren't in use. But that means the screen also goes dark while you are trying to read or watch a video. The fix: face-recognition software, linked to a webcam. This new approach to energy management puts the computer to sleep only when no one is looking at the screen, rather than after a fixed amount of time. Its makers say the program could save 80 per cent of the energy used by the average desktop each year.

Adding metal nanoparticles to the water used in geothermal energy could help tap the renewable resource almost anywhere on the planet. Traditionally, geothermal power plants need heat sources upwards of 160 °C. Unfortunately, only a few regions of the world reach that temperature at depths shallower than 5 kilometres. Some enhanced geothermal systems can run at only 65 °C but are inefficient, so the energy produced is expensive. Adding nanoparticles to water could improve the process, capturing as much as 30 per cent more heat with the same amount of liquid. Researchers at the Pacific Northwest National Laboratoy in Richland, Washington, plan a pilot study at the end of the year.
US: under development
A new generation of intelligent fridges could help smooth out fluctuations in the grid that arise from the irregularity of renewable power - by talking to each other. RLTec based in London has developed technology that lets fridges use supply and demand data from the grid to anticipate power surpluses or deficits and schedule when to turn on or off, thus avoiding sudden spikes in demand when supply is low. The company estimates the technology could reduce the UK's CO2 emissions by 2 million tonnes per year.

Every step you take uses energy. So why not recover some? US company PowerLeap has developed floor tiles made out of a piezoelectric material which generate electricity when deformed. It claims that 100 square metres of tiles installed in a busy area such as a train station could generate 18,250 kilowatt-hours per year.
US: under development
One large data centre can use as much energy as 30,000 homes, making it an area ripe for innovation. Sending all those servers to sea either on retrofitted cargo ships or specially designed vessels could cut the need for fossil-fuel energy by half, says Amin Vahdat, director of the Center for Networked Systems at the University of California, San Diego. Ocean-going data centres would use seawater for cooling, instead of mechanical air conditioning, and might be able to turn wave motion into a source of clean energy. Several companies are toying with the idea, but Vahdat estimates that it will be at least three if not five years before such a system would be seaworthy.

Solar power is great so long as the sun is shining, but the grid still needs back-up power to make it through the night. Soon, however, a 17-megawatt solar thermal power plant will provide stable power round the clock. The Gemasolar project, being built near Seville, Spain, will be the first commercial power plant to trap thermal energy from sunlight in molten salt, and will be capable of storing heat for up to 15 hours. This will be used to generate steam that drives a turbine to produce electricity.
