Check the Orientation of the plot

Find out where North is

As an earthship relies solely on the Sun for heating energy it was important to check which way was North.

I quickly ran up to the site with a compass.

Damn I need to get fit.. thats a long way up in the Swazi Sun

Here is a view of Plot2 from Plot 1, This will be the site of a larger build at a later date.

Here is a Vid taken from Plot2 before I got totally out of breath ;)

Solar panels going down

Sunday, June 1st, 2008

I read with much interest in the FT whilst waiting for our plane in Los Angeles that solar panels are going to drop in price this year. The reason being that for the first time they are being overproduced.

The article went on to say that the price of panels would be expected to get closer to the target of 1.00 dollar per watt. Current prices are about $3.40 a watt and are set to halve within a year.

Great news for us who are planning an Earthship build

Solar Energy

Wednesday, May 21st, 2008

Solar energy is energy from the Sun in the form of radiated heat and light. It drives the climate and weather and supports life on Earth. Solar energy technologies make controlled use of this energy resource.

Solar power is a synonym of solar energy or refers specifically to the conversion of sunlight into electricity by photovoltaics, concentrating solar thermal devices or various experimental technologies.

A solar panel is a device that collects and converts solar energy into electricity or heat which can be used by (for example) nearby buildings. Solar photovoltaic panels can be made so that the sun’s energy excites the atoms in a silicon layer between two protector panels. Electrons from these excited atoms form an electric current, which can be used by external devices. Solar panels were in use over one hundred years ago for water heating in homes. Solar panels can also be made with a specially shaped mirror that concentrates light onto a tube of oil. The oil then heats up, and travels through a vat of water, instantly boiling it. The steam created turns a turbine for power.
