Episode 4 – The basics of heat recovery ventilation From Efficiency NB, the Conservation Council of NB and Rogers TV comes Build It Better, an exciting new show examining the basic principles of building an energy efficient home. Join our own energy advisor Joe Waugh and the Conversation Council’s Julie Michaud in a 4 part series that looks at everything with a keen eye on efficiency: home construction, insulation, heating options, and other developing trends that keep the heat in and the heating bills low.
Efficiency NB has joined with the Conservation Council of NB and Rogers TV to bring you a new TV series to help you save money by learning how to make your home more energy efficient and reduce your greenhouse gas emissions. In these condensed ‘quick tips’, our own energy advisor, Joe Waugh, and Julie Michaud of the Conservation Council will explain how to set up an energy evaluation to identify where you are losing heat and how to plug those leaks. Theyll explore energy efficient upgrades for basements, attics, walls, windows and doors, they will share information on how to access advice and financial incentives, and also discuss the trends in energy efficiency. Part 2 – Why should I insulate my basement?
Presentation about the challenges of blade design for wind turbines given at Windpower 2009, Chicago,wind powervented by Siemens Wind Power, the IntegralBlade® technology manufactures wind turbine blades in one piece using a closed process. The glass fiber reinforcement is laid out to dry using a special molding arrangement with a closed outer mold and an expanding inner mold. After completion of the lamination of the glass fiber, the epoxy resin is injected under a vacuum. Following this injection, the blade is hardened at a high temperature while still enclosed in the mold. Once the blade is hardened, it is removed from the outer mold, and the inner mold is collapsed with a vacuum and pulled from the blade. The result is a complete, seamless blade finished in one process. More: www.powergeneration.siemens.com

THIS IS A 4 FOOT 8 INCH INVERTED PROP CARVING FOR WEST COAST DOUG. IT WAS ORIGIONALY INTENDED BY ME TO ROTATE CLOCKWISE , BUT I WOUND UP MAKING IT ROTATE COUNTER CLOCKWISE. I LABELED THIS AS AN INVERTED PROP BECAUSE THE WORD PROP MEANS PROPELLER. THIS DOES NOT PROPELL , THIS ABSORBS OR EXTRACTS POWER FROM THE WIND. IN ALL REALITY, THE ANGLES ARE INVERSE OR INVERTED. TO BE POLITICALY CORRECT; ONE HAS TO CALL IT AN INTERTED OR INVERSE PROPELLER. THE WORD BLADES, OR SET OF BLADES WILL WORK JUST FINE IN CONTEXT. THIS IS JUST A TERM THAT I COINED TO SAVE MYSELF FROM USING A TERM THAT I HATE TO USE. ANYWAY NTHIS ONE IS CARVED OUT OF WHITE PINE. ONE MIGHT THINK THAT IT SHOULD BE CARVED OUT OF A HEAVIER WOOD LIKE OAK , BUT THE HEAVIER WOODS ARE TOO HEAVY FOR THE ROTATION SPEEDS. THE LIGHTER WOODS LIKE POPLAR , AND YELLOW PINE WORK JUST FINE. VEDAR IS A GOOD WOOD, IT IS EASY TO WORK WITH AND IT LASTS A REALY LONG TIME. SOME CEDAR BLADES HAVE BEEN IN SERVICE FOR OVER 70 YEARS WITH NO SIGNS OF WEAR OR DETERIATION. PLEASE ENJOY THE DIFFERENT TECHNIQUES THAT I SHOW TILL YOU FIND ONE THAT MAKES IT SEEM POSSIBLE FOR YOUR SKILL TO ACCOMPLISH. IF YOU W2ANT TO MAKE WIND TURBINES I SUGGEST THAT YOU TRY TO CARVE AT LEAST ONE. IT WILL COME IN HANDY IN THE FUTURE. AND I THINK THAT A WOODEN PROP WILL GO MUCH FASTER THAN A PVC SET DUE TO THE SMOOTHER, MORE AERODYNAMIC DESIGN WITH LESS DRAG. IF YOU WANT TO EXTRACT ENERGY FROM THE WIND , THIS IS THE WAY TO DO IT. THANK YOU FOR WATCHING AND GOD …
Fourteen Harbor Freight individual solar panels from their 45 Watt kits. They are mounted on 2×4 frames with seven panels each giving 210 Watts of power for all fourteen. In the next couple of weeks we’ll install the other 14 panels for a total of 420 Watts, which combined with the previous 1600 of solar gives me 2Kw of solawind power also have 2Kw of wind power which I’m going to raise the tower to a total of 100 to 150 feet depending on cost. I expect the added height should produce 1Kw constant if not more.

This months highlights are; Meeting the Suns environment correspondent yes seriously. They’ve not had one very long but they do have one and he is serious about it – and: That amazing machine at Leeds University – the one that looks like it belongs on a Sci Fi film, in fact Im sure Ive seen versions of it, recreating humans from DNA samples In our case we used to make a gear lever assembly. As youll see here were getting close to the end game now, in fact Im ready to predict that episode 10 of 6 will see me driving the Wind Car for the first time !
