Carbon Tax is increasing
British Columbia is boosting its controversial carbon tax by $5 a tonne on July 1, further driving up the price of gasoline and other petroleum products as the province attempts to cut greenhouse gas emissions by 33 per cent below 2007 levels by 2020.
Environment groups have applauded the province’s carbon levy, which was offset by cuts to personal and corporate income taxes when it was introduced four years ago. The carbon tax has contributed to a 15 per cent drop in British Columbians’ use of petroleum-based fuels since it was introduced in 2008, said an Ottawa-based think tank, Sustainable Prosperity, in a report issued Wednesday.
At the same time the carbon tax on natural gas increasing from $1.2415 to $1.4898 per gigajoule. This constitutes 20% increase. Time to go green !

Vacuum Solar UV Collector
An evacuated-tube collector by Canadian Solar Technologies, contains several individual glass tubes,
each containing an absorber plate bonded to a heat pipe and suspended in
a vacuum. The pipe transfers the heat efficiently to a condenser
through the top of the tube. The condensers are clamped to heat
exchange blocks in a well-insulated manifold. A row of connected air-less glass tubes heat water through an evaporation and condensation process.
SEIDO EVACUATED TUBES were developed by Bejing Sunda and Daimler-Benz Aerospace. Over ten years of thorough research and development resulted in one of the most efficient designs in the industry. Absorber and heat pipe are mounted in a highly stable borosilicate vacuum glass tube. This prevents damage and the heat loss that occurs in conventional solar collectors. The absorber is sputtered with aluminum nitride selective coating to ensure high absorption and high efficiencies even on cloudy days
and under low temperatures.
Heat Pipe Technology
Heat pipes act like a low-resistance thermal conductor. Due to their thermal-physical properties, their heat transfer rate is thousand's of times greater than that of the best solid heat conductor of the same dimensions. Sunda's SEIDO heat pipe is a closed system comprised of two meters of copper tubing, an evaporator section, a capillary wick structure, a condenser section and a small amount of vaporizable fluid. The heat pipe employs an evaporating-condensing cycle. The evaporator section is tightly bonded to the absorber plate, where it captures the heat from the absorber and evaporates the liquid to steam, which moves up to the condenser section. The condenser protrudes out from the evacuated tube and is inserted into the heat exchanger manifold. There this steam will be condensed by water flowing through the manifold. Latent heat energy will be released to the process water through this phase change of vapor to liquid. In vacuum tube solar collectors, the condensation zone is at a higher level than the evaporation zone. The transport medium condenses and returns to the evaporation zone under the influence of gravity. This process is repeated continuously thereby heating the water in the solar loop.
Advantages of the Technology
High heat transmission rate
Fast Start-up
One-way heat conduction
The homogeneous heat distributing on the surface of the condenser
Selective Coating
The absorber is treated with an aluminum-nitride selective coating to achieve highest efficiency of the heat transfer. The coating is applied using a magnetic sputtering technique. This special optical coating transforms more than 92% of the incoming solar irradiation into heat and reduces less than 8% heat loss.
Advantages of the Technology
High absorbency to guaranty the effective heat from solar irradiation
Low emittency against the heat loss by heat emission
Evacuated Tube Technology
Heat pipes are inserted into the aluminum absorbers forming assemblies, which in turn are inserted into the glass tubes. The tubes are made of borosilicate glass which is strong and has a high transmittance for solar irradiation. In order to reduce the convection heat loss, glass tubes are evacuated to vacuum pressure of <10-5 mbar. Sunda uses a patented technique employing high heat and pressure to insure stable glass-to-metal vacuum seals. In order to keep the stability of the vacuum for a long time, a barium "getter" is used. Through evacuating air out of the glass tube the absorber material and the selective coating are protected from corrosion and other environment influences. This ensures a lifetime of at least 15 years without loss of efficiency.
Advantages of the Technology
Effective hermeticity
Resistance in harsh environments, e.g. against corrosive materials, vibrations, serious temperature fluctuations
Long-term, reliable protection of the packaged component --------------------------------------------------------------------------

Sun Peaks Fire Hall Sustainable Energy upgrade
Sun Peaks Resort Municipality makes the first step toward the efficient and sustainable energy use.
Monday July 9, 2012 the work begins on the first phase of the Sun Peaks Fire Hall facility upgrade. It involves upgrade of the office building with the state-of-the-art high-efficiency air-to-air system, which can work in reversible mode. It provides heating in winter and cooling in summer consuming up to 3 times less electricity than currently used electrical baseboard heaters and conventional wall-mounted air-conditioning units. Automatically maintaining comfortable temperature and performing constant air circulation, the system provides a healthy environment in the building. The "intelligent eye" feature of the system reduces the level of heating or cooling when no occupancy detected in the building, and automatically brings it back to the preset level when the occupancy is detected.
The next part of the planned upgrade is installation of the solar thermal system to provide hot water needs for the facility. It will include space-age vacuum tube efficient solar UV collector technology which will practically eliminate the need for the electric boiler, which will be kept as a back-up only.
Stay tuned for further updates !
