Green Life Gadget

Most people find change difficult but not the children. They embrace new things, they are eager to learn new things. So it will be wise to let them learn and experience alternative sources of energy to help create a greener future. This is a wonderful introduction to OWI’s newest series: Plug-in Solar Rechargeable kits.

 Kids can build an eco-friendly and Green Life future. They can see the benefits of putting solar energy to work and discover how solar cells generate electricity from light. The kit consists of a powerful solar cell, rechargeable battery (included), house, and car. It is easy to assemble: no screws, nuts, or fuss. Just simply plug-in the car into the house, solar energy converts into electric power for storage and application. On a sunny day, charging is complete in 3 minutes. Run time is fun time. Once released from the house, the car will venture and explore for you for three minutes.

Unprinter

Researchers at the University of Cambridge in the UK have developed a method for removing laser-printed text from paper. It could mean devices used for security, recycling or both.

The technique worked by using the laser beam to apply the right level of heat for a mere four billionths of a second. It isn’t a case of the words dropping off the page: the heat vaporized the toner, with the resulting gas being captured in a filter. Allwood says the technique worked on a range of toners and does not damage the paper or leave it unable to “receive” toner in the future.

Type 1 Plastic

Type 1 Plastic – Polyethylene Terephthalate (PET, PETE)

Type 1 is PET and PETE or polyethylene. Such types of plastics are commonly used in water bottles. The acronym PETE (polyethylene terephthlate) or PET (poly ethylene terephthalate) are often used interchangeably, to refer to type 1 plastic. PET or PETE plastics are often used in soft drink bottles, as well as food and non-food containers, because of their good gas and moisture barrier properties. PET and PETE plastic can be recycled into carpet yarns, fiberfill, tote bags, food and drink containers, luggage and clothing.

Type of Plastics

Types Of Plastics

• Type 1 is PET and PETE or polyethylene. Such type of plastics are commonly used in water bottles.  
•  Type 2 is HDPE or high density polyethylene. Commonly used in trash and shopping bags. Also in the milk jugs.   
•  Type 3 is PVC or polyvinylchloride. PVC piping is the most common form of this plastic type.
• Type 4 is LDPE or low density polyethylene. This type is used in the packaging of frozen food.
• Type 5 is polypropylene of PP. Tupperware, disposable cups, etc. are some examples of polypropylene.
• Type 6 is PS or polystyrene. These plastics are use in egg cartons and packing peanuts.
• Type 7 refers to all the remaining types of plastic.

Tsunami and Earthquake in JAPAN

The world is in distress, that tsunami is back again and this time in Japan. The Sendai earthquake and tsunami was an 8.9-magnitude earthquake and resultant tsunami waves. It was located off the east coast of Tohoku, Japan on Friday, March 11, 2011 at 05:46:23 UTC at a depth of 32 km. Originally a 7.9 on the Moment magnitude scale, it was upgraded to an 8.8, then again to an 8.9 by the United States Geological Survey making it the largest earthquake to hit Japan in recorded history.

This earthquake has triggered a tsunami scare not only for Japan's Pacific coast but various other countries like New Zealand, Australia, Russia, Guam, Philippines, Indonesia, Papua New Guinea, Nauru, Hawaii, Northern Marianas (USA) and Taiwan. A 10-meter tsunami was observed at Sendai airport in Miyagi prefecture, which has been flooded, with waves sweeping along cars and buildings as they traveled inland.

What is Tsunami? A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean, but can occur in large lakes. Tsunamis are a frequent occurrence in Japan. Approximately 195 events have been recorded so far in Japan. Earthquakes, volcanic eruptions and other underwater explosions, landslides and other mass movements, and other disturbances above or below water all have the potential to generate a tsunami.

The Greek historian Thucydides was the first to relate tsunami to submarine earthquakes, but understanding of tsunami's nature remained slim until the 20th century and is the subject of ongoing research. Many early geological, geographical, and oceanographic texts refer to tsunamis as "seismic sea waves."

Recycling Plastic Bags

Plastic bags are huge factor in unstable environment; but at the same time plastic bags are in used globally on a large scale for various purposes. They are manufactured from the low density polythene which is a non-biodegradable product. Although they can be degraded through photodegradation, the process involves release of small toxic products which are hazardous to the environment. Improper disposal of polythene bags and its non-biodegradable nature, thus, makes plastic a threat for the environment. When these plastic bags are deposited on the ground, it results in clog landfills. It is because of its inability to degrade plastic bags. Plastic bags when accumulated on water can become harmful to the marine life. So for all these reasons and many more recycling of plastic bags is mandatory. Recycling can also saves a lot of energy, as the process of manufacturing plastic bags demands a huge amount of energy. The process of recycling consumes 20%- 40% lesser energy for the production of new products. So it is win-win situation for everyone.

In addition to reducing the amount of plastics waste requiring disposal, recycling plastic can have several other advantages:

1.      Conservation of non-renewable fossil fuels - Plastic production uses 8% of the world's oil production, 4% as feedstock and 4% during manufacture.

2.      Reduced consumption of energy.

3.      Reduced amounts of solid waste going to landfill.

Reduced emissions of carbon-dioxide (CO2), nitrogen-oxide (NO) and sulphur-dioxide (SO2).
