A recent Auburn University study provides some real numbers to back a theory we’ve all known was true for some time—planting a shade tree near your home reduces energy bills significantly in the spring and summer months. The study, conducted in Auburn,
Alabama, included 160 homes with different levels of shade. Each home’s energy usage was monitored and compared to other houses with similar energy— using patterns, size, type of cooling system, etc. Here are some highlights from the study:
Houses with trees on the west side of their home had a “much lower power bill”.
Older homes had the most shade coverage, because people did not use to rely on air conditioning as much to keep them cool.
Children under age 12 consume the most power in a home as they watch television, play games and frequently leave lights on.
Fall and early winter are the perfect seasons to plant a tree. This time of year many nurseries（苗圃）are trying to reduce their inventory of trees heading into the winter, so you may find a deal on trees easily to plant around your lot.
While you have the spade out, consider planting a tree near your outside air conditioning unit. The shade will keep the unit cooler and help it operate more efficiently. Be sure to plant far enough from the unit to allow proper airflow, and account for the tree’s growth over time.
It actually hurts to watch the trees being knocked over when land developers plan neighborhoods because trees could provide much needed shade to new homeowners, reducing their electric bill and the amount of energy they consume. Hopefully this study, and more like it in the future, will encourage developers and builders to plan around trees as much as possible to offer homeowners a shaded lot.

Clothes can make phone calls, play music, dial your pal’s number, keep you warm during cold weather and operate your computer?
This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes — clothes that have minds of their own! Scientists, working for the company, have invented a kind of fabric that can be blended(混合) with flexible electronic materials to create intelligent clothing. The result are electronic garments.
If you think the wearer has to be wired to different devices, think again. These designer clothes are wire-free, soft to touch and washable!! Like any electronic device, these high-tech clothes have to be powered. Currently, a tiny nine-volt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100 percent shock proof, they say.
The Electrotextiles team has also created the world’s first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These ‘lap- tap’ gadgets(器具) are all set to take over laptop computers!
Another useful garment is the shirt-cum-mobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(风帽) and the electronic ski jacket with a built-in heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.
Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?
