The bigger the composting pile is, the least turning it needs, because most of the pile remains sheltered from the dry / temperature-changing outside.
If you want to have a compost at your place with limited space to handle it, the best is probably to turn towards vermicompost. You don't need a big pile for this, and worms will do the turning for you. Great ...
When you seal everything airtight the contents of your bin will start to decompose anaerobically. There are no big problems with this, but there are a few downsides:
anaerobic decomposition is slower than 'regular' aerobic composting
during anaerobic decomposition methane gas is formed which is a much more potent greenhouse gas than the CO2 that comes from ...
Clarification of terms: Your tap is the downstream end. The City water supply is the upstream end.
My understanding of your situation:
Building shutoff vale
Local distribution valve
Tap you trickle.
I don't know that your building valve and local distribution valve are or are not the same.
You want to know if it's safe to use ...
TL, DR Solar thermal with a gas burner for peak demand. Possibly improved isolation.
First, you need exact data on how much heat you need, and when, during the year and during each day.
This should help you get an idea if the insulation of your house can be improved. Once you have the numbers, ask here for a first orientation. Without seeing the house (...
You can make your own filter, I think.
When I was kid my father and I constructed our own filter, everything you need is some sand, 'dust coal' and a couple of stones and wool. You can use a bottle of soda, or something like that.
Put the wool on the 'mouth' of the bottle, then put in the coal, stones and sand. Put another bottle under the will to ...
You could definitely switch to an efficient gas boiler system with proper controls to run "cleaner" and more efficiently. Depending on gas/oil prices in your area, this may or may not be economically beneficial (short or long term).
Varying with your current setup, electrical prices in your area (and their generation method) you could also change about ...
First, you should really find out what is causing your high electric bill.
You can use watt-o-meter, or simply search. Concentrate on big power eaters, especially anything with heater elements.
There is little point in saving 5 Watts for 10 hours by turing off your power strip when you're not around, but use clothes dryer which uses 1000 Watts for 2 hours (...
If you don't have that refrigerator yet and you are a small household, consider what they sometimes have in camping vans. They put a solar panel on the roof and use it to top up a normal 12 volt car battery. This is then used to run a little 12 volt camping refrigerator.
If your needs are small then this is a cheap and mobile way to solve your problem.
I'll assume for now the earlier answer on indoor heating systems that you linked remains correct, and address two other points.
Heat pump efficiency and temperature
Engineering toolbox provides a thorough explanation of heat pump performance, which includes this chart:
A few definitions:
COP stands for coefficient of performance, and is a measure of heat ...
I can't imagine this will cause you any problems. The only difference is the anaerobic (no oxygen) bacteria will be doing more work in your sealed container instead of aerobic bacteria (requiring oxygen). Aerobic is faster. But as you have no use for the hummus (sad). You should be fine.
Here's a link: if you are more interested
Something I've been experimenting with for lighting is called the "Alum Battery" (a good search phrase for youtube or google). If you can find a cheap enough source of aluminum sulfate, you can actually take a battery that will no longer start your car, lawn tractor, motor cylce etc. and convert it to a different kind of battery by replacing the Acid with ...
If you have it available switching to natural gas will produce less CO2.
If you have renewable energy surpluses, then TES (Thermal Energy Storage) makes lots of sense. You use MUCH larger water tanks, and heat it electrically when there is a surplus of power. Your air systems can be heated with hot-water fan coils -- cheap conversion.
Look at roof ...
I know it is not easy, but it starts when you are looking for a new flat to rent. That is the moment when you can influence most your later possibilities to save energy or to live sustainable. Beside of other aspects ask yourself.
When and how was the house build? As long as cheap construction is profitable and if everyone accepts cheap construction with ...
Do an inventory of all the light fixtures in your apartment, and re-distribute light bulbs based on how much light you need and how often you need it.
First, for each bulb you have, determine the type (incandescent, CFL, or LED) and wattage. Use a chart like this one to compare brightness:
Then, follow a few simple guidelines to determine where to put each ...
