ECOFriendly Thermosyphon solar water heater
Solar energy can be converted into power by using a solar thermal equipment. The thermosiphon (thermosiphon or monobloc) solar water heater is one of the simplest, most economical, and, I believe, the best type of solar water heater. It’s a passive system, meaning that it has no mechanical or electrical devices that make it work. Only the sun’s energy is needed to heat the water in the solar collector and circulate that water through the holding tank.
Hereafter are some general rules you should be aware when to build and install your own thermosyphon solar water heater.
1. Basic plumbing and carpentry skills are required to build this system, especially the skill of soldering copper pipe and copper fittings together using a propane torch and 95/5 solder, with flux.
2. Solar collector must face south
3. For maximum year round gain, the collector angle should match your latitude.
4. The solar collector needs six hours of direct sunlight per day to heat all the water in the holding tank.
5. Solar collector won’t work in the shade.
6. During freezing weather conditions, all water must be drained from the solar collector, or freeze damage will occur.
7. Use standard hot water heater as the holding tank for your thermosyphon solar water heater. When adequate solar energy is not available use the heat
source in the tank as back-up.
source in the tank as back-up.
8. Use only copper pipe and copper pipe fittings for this system. Do not use any PVC or plastic pipe in this system.
9. In a thermal siphon system, the tank must be behind and above the solar collector and piped.
10. Insulate all exposed pipe with foam pipe insulation, 3/4 inch i.e. by 3/4 inch wall.
11. For the thermosiphon solar water heater to work properly, it must be full of water under pressure with no air pockets inside the system. A gate valve is installed at the highest point in the system to manually vent air from the system during initial fill up.
12. Before you buy any materials, make a drawing of your system and estimate the amount of lumber, pipe and fittings, glass, etc. that you will need.
The Sun is a gigantic fusion reactor which radiates energy into space. The amount of energy our planet receives in one hour from the Sun is of the same dimension as the world energy consumption in one year. This energy drives the water cycle, causes winds and provides light and heat. The use of these renewable sources of energy is becoming crucial for future and carbon reduction strategies. Act now buy bring a solar water heater to your home.
ECOFriendly Solar Roadways
A solar roadway is a road surface that generates electricity by solar power photovoltaics. One current proposal is for 12 ft x 12 ft (3.658 m x 3.658 m) panels including solar panels and LED Signage, that can be driven on. The concept involves replacing highways, roads, parking lots, driveways, and sidewalks with such a system
A solar roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace current petroleum-based asphalt roads, parking lots, and driveways with solar road panels that collect energy to be used by homes and businesses, and ultimately to be able to store excess energy in or alongside the solar roadways. Thus renewable energy replaces the need for the current fossil fuels used for the generation of electricity, which cuts greenhouse gasses.
Parking lots, driveways, and eventually highways are all targets for the panels. If the entire United States Interstate Highway system were surfaced with Solar Roadways panels, it would produce more than three times the amount of electricity currently used nationwide
Existing prototype panels consist of three layers.
- Road surface layer – translucent and high-strength, it is rough enough to provide sufficient traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. This layer needs to be capable of handling today’s heaviest loads under the worst of conditions and to be weatherproof, to protect the electronics layer beneath it.
- Electronics layer – Contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element with a view to reducing or eliminating snow and ice removal as well as school and business closings due to inclement weather. The microprocessor controls lighting, communications, monitoring, etc. With a communications device every 12 feet, a solar roadway can be an intelligent highway system.
- Base plate layer – While the electronics layer collects energy from the sun, it is the base plate layer that distributes that power as well as data signals (phone, TV, internet, etc.) down the line to all homes and businesses connected to the solar roadway. It needs to be weatherproof to protect the electronics layer above it.
Renewability and lifespan
The main advantage of the solar roadway concept is that it utilizes a renewable source of energy to produce electricity. It has the potential to reduce dependence on conventional sources of energy such as coal, petroleum, and other fossil fuels. Also, the lifespan of the solar panels is around 30–40 years, much greater than normal asphalt roads, which only last 7–12 years.
Military and rescue assistance
In the event of an environmental disaster or military emergency, solar roadways would provide power when it is needed most. As solar power is renewable, it obviously requires no external connection to an artificial power source.
Roadways already in place
Another advantage of solar roadways is that they do not require the development of unused and potentially environmentally sensitive lands. This is currently a very controversial issue with large photovoltaic installations in the Southwestern US and other places. But since the roads are already there, this is not an issue. Also, unlike large photovoltaic installations, new transmission corridors – perhaps across environmentally sensitive land – would not be required to bring power to consumers in urban areas. Transmission lines could simply be run along already established roadways.
With induction plating embedded inside these roads, electric cars can be recharged while in motion on top of these roads. This would reduce the costs and the time inconvenience of waiting at a charging station.
In spite of these advantages, initially, the start-up and maintenance costs of building such roadways and parking lots may be high although advances in this technology should cause the costs to fall. Road surfaces also accumulate rubber, salt, etc., which block sunlight. Salt might be easy to wash off, but not rubber.
Here is some ECOFriendly project that utilized Computerized Civil Engineering to its full potential
The Palm Islands (consists of 3 islands to form the shape of a palm tree) are an artificial archipelago in Dubai, United Arab Emirates, off the coast of the Persian Gulf. Major commercial and residential infrastructure will be constructed by Nakheel Properties, a property developer in the UAE.
Most Interesting thing about the is that they can be seen from outer space, such is their size.
They add an additional 60kms of shoreline to the city, increasing the coastline of the UAE by an astounding 166 %
With the islands being artificial, everything has had to be built from the ground up. What this means is that there are no palm trees on the islands despite the group’s name therefore 12,000 are being grown in a nursery to place throughout the islands to make them look more authentic.
Before the building of the islands took place, expert divers went to inspect the rock formations under the sea to guarantee their stability. There were also over 100 tests conducted to be sure that the project was feasible. In the end, all tests were positive and the project got a green light.
Each island required a total of seven million cube meters of rock and 32 million cubic meters of sand in its construction. Most of the sand came from the ocean floor.
From one end to another, the rock and sand were equal to a two-metre high, 50cm thick wall. This wall would be long enough to circle the globe three times. No other project has ever been built that has required a similarly large amount of materials.
Quadracci Pavilion Of Milwaukee Art Museum
The graceful Quadracci Pavilion is a sculptural, postmodern addition to the MAM -Milwaukee Art Museum completed in 2001, designed by Spanish architect Santiago Calatrava. A 1975 addition had increased space five-fold, but the Museum remained hidden from public view on the lower floors of the War Memorial Center. A $10 million then-anonymous gift from Betty and Harry Quadracci kicked off a capital campaign. In 1994, the Museum’s search committee convinced Santiago Calatrava to submit a proposal and was wowed by his creative design. Calatrava, inspired by the “dramatic, original building by Eero Saarinen, …the topography of the city” and Frank Lloyd Wright’s Prairie-style architecture, initially proposed a small addition, with a pedestrian bridge connecting the Museum to downtown. As excitement over the project grew, fundraising accelerated and the project evolved, with the architect and Museum trustees sharing ideas. The 142,050-square-foot Quadracci Pavilion was planned to primarily contain public spaces—a reception hall, auditorium, cafe, store, and parking, plus 10,000 square feet of flexible space for temporary exhibitions. Calatrava later said, “I had clients who truly wanted from me the best architecture that I could do. Their ambition was to create something exceptional for their community…. Thanks to them, this project responds to the culture of the lake: the sailboats, the weather, the sense of motion and change.” The structure incorporates both cutting-edge technology and old-world craftsmanship. The hand-built structure was made largely by pouring concrete into one-of-a-kind wooden forms. It is a building that could have only been done in a city with Milwaukee’s strong craft tradition.
