According to reports, Popular Mechanics Magazine recently selected the 2011 Environmental Protection Breakthrough Award and will announce the winners at the Hearst Building in New York City recently. These award-winning products combine innovation and environmental protection. The design is inspired by nature or may greatly improve the environment. The following are the nine most beneficial inventions for the environment:
1, Philips Ambient LED bulbs
Philips has introduced a new Ambient LED 12.5-watt LED Bulb that can replace 60-watt incandescent bulbs. Its design meets or exceeds the US "Energy Star" energy-saving standard. Philips said that the new bulb is rated for 25,000 hours.
2, light Radio
Light Radio is a mobile broadband infrastructure developed by Bell Labs, an Alcatel-Lucent company, a global telecommunications equipment manufacturer. With the integration of cloud technology, SOC, and antenna matrix, light radio is committed to solving the predicament that operators are faced with a surge in bandwidth requirements, high energy consumption of network equipment, and high operating costs.
The initial idea of ​​light radio was proposed by Dr. Tod Sizer, vice president of the Wireless Research Department of Bell Labs. After a year and a half of feasibility studies and technical research and development, the huge communication base station was made into a small Rubik's Cube size. Light Radio finally completed this year. Officially released on the month. Light Radio will completely subvert the existing mobile and broadband infrastructure, significantly simplifying the mobile network structure.
3, magical glass powder that can absorb the dirt in water
Can glass be used to clean the water? It's incredible. The latest discovery by Professor Paul Edmiston of Worcester College in the United States is beyond the imagination of ordinary people. He found a magical new glass that could adsorb petrol and other volatile organic compounds, but not with water. Magic glass can be used to treat contaminated groundwater.
4, reduce the use of new solar panels
Solaria develops new solar panels. It uses plastic lenses to focus sunlight on traditional solar cells cut into thin strips, which greatly reduces the use of silicon and reduces the use of silicon by 50% to 70% compared to traditional solar panels, significantly reducing costs.
5, eat smoke roof tile
After the roof tile is coated with titanium dioxide, it can neutralize the nitrogen oxide particles in the smoke. Therefore, it is called “eating smoke roof tilesâ€.
6, high-altitude wind turbine
Corwin Hardham, Kenny Jensen, and Damon Vander Lind created a high-altitude wind turbine that works like a helicopter when taking off. Like an airplane. High altitude winds have always been very strong, and the air there will be a treasure trove of energy with unlimited potential. This high-altitude wind turbine is a device that uses high-altitude wind power to generate electricity. Because of its environmental protection and pollution-free advantages, scientists are trying to use this technology to supply electricity to cities.
7, ultra-low fuel efficient engine
Peter Hofbauer, chief executive of EcoMotors, an eco-friendly car engine technology developer, developed a two-cylinder diesel engine with opposed-piston opposed-cylinder technology (OPOC) for five small cars. Created ultra-low speed fuel consumption of 2.35 liters per 100 kilometers. This engine does not differ much from the normal diesel engine, but it has a higher power density and can reduce carbon emissions. According to Professor Hofbauer, the OPOC engine is 30% lighter and 4/4 smaller than the current best turbocharged diesel engine, and the fuel consumption per 100 kilometers is reduced by 50%. The construction of the OPOC engine is very special. Two cylinders are arranged around each other. There are two opposing pistons (always in the opposite direction) in each cylinder. The four pistons are connected to the central crankshaft via connecting rods. The gas, work and exhaust processes are the same as those of the two-stroke engine. The two opposing pistons are cylinder heads.
8. Hummingbird Reconnaissance
US researchers Matt Keennon, Karl Klingebiel, and Todd Hylton have developed a remote-controlled microscopic reconnaissance plane that resembles a hummingbird. Hummingbird reconnaissance aircraft is a new type of artificial aircraft that breaks through aerodynamic design constraints. It is only 16 centimeters in length, flapping its wings to maintain flight, flying 17.7 kilometers per hour, can withstand wind speed of 8 kilometers per hour.
9. Energy-saving hybrid electric vehicle
A group of middle school students from the West Philadelphia School of Technology and the West Philadelphia Mixed X Team developed a safe, comfortable and energy-saving hybrid electric vehicle and participated in the famous International "Progressive Auto X Grand Prix" and won the championship. This is a hybrid car with a speed of 150 miles per hour (about 241.4 kilometers) and 100 miles (about 161 kilometers) per gallon of oil. These 15-year-old middle school students learned to learn basic automotive knowledge, and then learned how to use it to create cars that are not only energy-efficient but also reliable, fast, and trendy. They have won a series of national competitions. Their vehicle-building technology can even surpass professional engineers.
How about straw hat LED Lamp Beads and patch lamp beads?
1. From the appearance: straw hat shaped LED lamp beads are straw hat shaped round (hence the name), with long pins; Most SMD LED Lamp Beads are rectangular, with no pins or only very short pins (a kind of manual SMD high-power lamp beads are also round, except those with short leads);
2. From the light emitting point of view: the angle boundary of straw hat lamp bead is obvious, and the patch lamp bead is not obvious;
3. From the perspective of soft light: the light of straw hat lamp beads is more dazzling, and the light of patch lamp beads is softer;
4. From the perspective of packaging lens: the lens of straw hat lamp bead is hard and transparent epoxy resin, and the patch lamp bead is mostly soft and transparent silica gel;
6. From the perspective of power: the power of straw hat lamp beads is small, and the power of more than 0.5W is less (because it is not easy to spread heat). The lamp bead power of the patch can be larger. For example, the 5050 packaged chip lamp beads can achieve a 3W power, but the straw hat shaped lamp beads cannot.
