香菸與汽車

前幾天看到一個廣告 好像是有關汽車的吧 上面有一位爸爸與一個模仿他的兒子 這樣的廣告其實還不少 只是不知道為何那個廣告 我看的有點噁心 是色調的關係吧 不是明亮的藍色 綠色 而是金黃色 讓人覺得比較尊貴 可是我卻覺得好像香菸廣告 當下就想到或許有那麼一天 我們的社會也會明白 香菸汙染人們的肺時 其實汽車也汙染著我們的大氣 希望有那麼一天 我們也會在方向盤上 車身上打上 "開車有害自然環境 請多使用大眾交通工具 愛護地球"

13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence Read more: 13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence | Inhabitat - Green Design Will Save the World

While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it’s a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design.

Israel to Get Electric Car Battery Swap Stations

Better Place offers one package that includes the cost of the car and three years of driving 25,000 kilometers per year for $46,000. The company says this price amounts to a 35 percent savings over buying and fueling a gas car in Israel over three years. Other packages include a cost of about $36,000 for the car, with monthly subscription fees ranging from $320 to $470 a month for 20,000 to 30,000 kilometers of driving per year, respectively. For both packages, the price includes the installation of a charging station at home.

Timon Singh Wave and Solar-Powered Robot

The Wave Glider is a solar and wave-powered robot designed by Liquid Robotics to serve as a platform for ocean observation, data collection, intelligence, surveillance and reconnaissance. The project has just been awarded $22 million in Series D financing, which will go to further its development as it begins to explore the ocean blue.

The EnduraLED A21 17-watt uses the company’s high-power, next-generation LUXEON LEDs. This new technology was developed to meet or exceed Energy Star qualifications for an LED-based replacement for the 75-watt incandescent light bulb. The cool thing about it is that the bulbs deliver 1100 lumens with just 17-watts of electricity. They also have a color temperature of 2700k, a color rendering index (CRI) of 80, and a rated life of about 25,000 hours.

The benefits however, don’t stop there. The EnduraLED A21 17-watt could save about $160 per bulb. The bulb will be available in stores during the fourth quarter of 2011 in the US. The initial suggested retail price is $40 – $45. Although higher than standard incandescent and CFL bulbs, the fact that the EnduraLED will save more in terms of energy cost, and lasts 25 times longer than other bulbs makes it definitely worth the price.

Self-Cleaning Solar Panels

Dust has also bedeviled solar installations on Earth. For example, dust storms have cut power production by 40 percent at a large, 10-megawatt solar power plant in the United Arab Emirates. Washing the panels can be time-consuming or require costly automation--and it takes a lot of water, a precious resource in the desert. "With this new technology, solar panels can be automatically cleaned without water or labor," Mazumder says.

The system takes advantage of the fact that most dust particles, particularly in dry environments, have an electric charge. A transparent electrode material such as indium tin oxide delivers an alternating current to the top surface of the panel. As it swings between being positively and negatively charged, it creates an electric field that repels positively and negatively charged particles. The electric field also helps to impart a charge to uncharged dust particles, allowing them to be quickly repelled as they come in contact with the panel. The researchers have designed the system so that the electric field works its way from one side of the solar panel to the other, gradually moving the dust along until it falls off.

Micro hydro generator

Micro hydro power is clean, renewable energy. Here is a micro hydro generator which can supply stably output voltage and output current with the help of one voltage stabilizing circuit and one rechargeable battery. We can install it at home to save household energy, like using spray shower to light LEDs etc.
