Soon we're ready for "launch"

Progress:
Finally the team has agreed to install a separate ventilation loop that will send cooler air from the cellar to the 4 bedrooms (as we originally planned). I expect this solution to make our bedrooms cooler than the other rooms all year long. This is how we want it, and at the same time the lower temperature in the bedrooms will give us reduced energy for heating as a bonus.

Yesterday, I also pointed out that they had forgotten to ventilate the ventilation room. Yes, there is a lot of piping and equipment there, but no ventilation of the room itself (adding fresh air and pulling out "used air"). They have agreed to fix this tomorrow.

They have also promised to connect the outdoor part of the heatpump to the rest of the system tomorrow morning. Hopefully the electrician will also show up and provide them with the hook-up they need to start the ventilation system and the heatpump. We should then be able to start the system (even if they'll still be installing the extra loop to the bedroom).

My hope is that everything is finished by the end of this week - but I have been disappointed before, so we'll just have to wait and see.

Events:
In Norway there is currently a heated debate about biodiesel. Because it seemed like a good idea at the time, the government adopted a new law that says all diesel sold in norwegian gas stations must include at least 2.5% biodiesel (later this will be raised to 5%). Today they added an extra tax on bio-diesel.

I guess the reason for the new tax is that they now see that biodiesel, while CO2 neutral, have serious negative effects that politicians were not aware of at the time (?):

• CO2: Rainforests have to yield to plantations that will grow biological material for the production of biodiesel. A lot of CO2 is going up into the atmosphere as a result of burning the trees, and in the future these trees will no longer slurp CO2 from the surrounding air and produce O2 (as part of the photosynthesis)
• Food: Farmland is transformed from growing food to "grow biodiesel". Many people worry about the planet's ability to feed all the people living here - and we don't need this effect !

The thing many people don't understand (myself included) is that they're not removing the 2.5% rule. The tax will therefore not affect the amount of biodisel used in Norway - just adding more tax. The only positive thing you can say about this move is that all tax on fuel could theoretically reduce the use of cars running on fossil fuel.
