DIY Alternative Energy, Build Your Own Solar Power

- Adam Clare

Ever wanted to build your own energy network? Well, now you can!
This guy made his own solar power unit.

So what is a solar panel anyway? It is basically a box that holds an array of solar cells. Solar cells are the things that do the actual work of turning sunlight into electricity. However, it takes a lot of cells to make a meaningful amount of power, and they are very fragile, so the individual cells are assembled into panels. The panels hold enough cells to make a useful amount of power and protect the cells from the elements. It doesn’t sound too complicated. I was convinced I could do it myself.

I started out the way I start every project, by Googling for information on home-built solar panels. I was shocked at how few I found. The fact that very few people were building their own panels led me to think it must be harder to do than I thought. The project got shelved for a while, but I never stopped thinking about it.

Gray Water Getting More Interest

- Adam Clare

Gray water is such a simple idea, but it is expensive to implement the infrastructure on a mass scale – particularly in the suburbs. There is however, more interest in the idea thanks to an increased knowledge about how important water is. Californians are now looking more at gray water – and in the USA California tends to set trends for the rest of the states.

The systems — which use water from sinks, tubs and washing machines to irrigate home landscaping — are touted as a way to keep lawns green and flowers blooming without abusing a scarce resource or inflating water bills.
Greywater Guerrillas launched its first jerry-rigged experiments with gray water in 1999, when the original guerrillas were trying to reduce the water bill for their house of six roommates. The systems and devices have become much more sophisticated since then, said Laura Allen, an educator with Greywater Guerrillas.
Gray water systems channel the used household water (though not from toilets) to irrigation ducts 9 inches below the surface of a home’s lawn or garden.
Advocates say it’s a practical use of water that otherwise would go into the sewer system, and therefore an expedient means of conservation. And conservation is important as water becomes an increasingly valued resource, proponents say.
“Our water bill is going to be like our oil bill in the future,” said John Russell, a landscape designer who heads WaterSprout, an Oakland company that specializes in residential and commercial irrigation, including gray water systems.

Wave Powered Boat Succeeds

We first looked at the wave-powered boat back in March, before Kenichi Horie set sail (or is that set wave?). Now he has become the first person to cross the Pacific in a wave-powered boat.

Weak waves and opposing ocean currents delayed his arrival, which was originally set for late May.

“When waves were weak, the boat slowed down. That’s the problem to be solved,” the adventurer told reporters Saturday from aboard his catamaran Suntory Mermaid II off the Kii Peninsula in western Japan.

The 9.5 metre (31-foot) boat is equipped with two special fins at the front which can move like a dolphin’s tail each time the vessel rises or falls with the rhythm of the waves.

Horie, who will turn 70 in September, reached his destination in the channel between the main Japanese islands of Honshu and Shikoku just before midnight (1500 GMT Friday) after covering some 7,000 kilometres (3,780 nautical miles) from Hawaii without a port call.

“The feeling is yet to sink in,” Horie added, according to the Jiji and Kyodo news agencies. “I want to go home as soon as possible and eat home-cooked meals.”

Horie first made world headlines in 1962 when, at the age of 23, he became the first person to sail solo across the Pacific.

Bicycles Are Amazing: 17 Reasons Why

- Adam Clare 2 Comments

Bicycles are perhaps the greatest thing that human civilization as ever created – at least that’s what I think. With the increasing price of gas and better environmental awareness bicycles are gainig popularity in the “developed world”. Eco Wordly has put together a list of 17 reasons why bicycles are the most popular vehicle in the world.

Some highlights from the list:

4. Bicycling builds social groups and better community development.

In Reggio Emilia, Italy, the “BiciBus” brings teachers, students, and parents together for bicycle commuting to and from schools.

“The BiciBus is a ‘two-wheeled bus,’” writes Italy correspondant, Eva Pratesi. “It consists of a group of students who go to and come back from school guided by volunteers by bicycle (parents, grandparents, teachers…). The students go to the route with their bicycles; they wait for the volunteers and the group and go on together toward the school.

BiciBus is preceded and supported by workshops and technical analysis in the classrooms to educate to sustainable mobility, traffic safety and bicycle knowledge. It’s also possible to organize school trips by bicycle an evening meetings with experts directed to the families in order to talk about health, sustainable mobility and safety.”

In Australia, a similar community bicycling program offers a similar program for adults as well. Cyclists can join the “Bike Bus,” a regularly scheduled commute with fixed routes and two commuting speeds: social and express.

San Francisco, California, has a third option. Though not as organized as a community bike bus program, the San Francisco Bicycle Coalition can pair cyclists with “bike buddies” to share knowledge and tips or commute together to work.

12. Bicycling could save the average American at least $250,000.

According to Motor Trend and the American Institute for Economic Research, the average American car-owner can expect to pay between $240,704 and $349,968 during his driving lifetime. These figures will increase with the price of fuel and the rising cost of the vehicles themselves.

A bicycle can serve your transportation needs for commuting, shopping, and getting around town. Urbanites who are well acquainted with the frustration of paying parking tickets and towing fines will also find that bicycles are an excellent solution. Of course, you’ll still need that fuel: the occasional sandwich or cup of coffee will do nicely.

14. Bicyclists breath in less air pollution.

Various studies indicate that bicyclists breathe in less air pollution, making cycling an even more healthy activity. Of course, bicycles emit no air pollution themselves, which ensures cleaner air and better lung health for everybody.
