Either earthen structure, strawbale, cob, rammed earth, bamboo, compressed earth block, etc.The only difference with this idea is combining current technologies to form a completely self-sufficient and extensive living system. ALL technologies have been proven, tested, and people use them every day. The greatest part about this “off-the-shelf- hybrid system, is it will work. They need to secure themselves and their families first, making sure things are provided for their loved ones and themselves. Once they have that, they can think about the future. People need a place to live and call home. Innovation can come “ after” the system is built and there is time to think and ponder on how to improve the system. The energy efficient system is designed to combine current off-the-shelf technology which is proven and affordable, creating a hybrid system of living that provides the necessities, comforts, and some of the luxuries of traditional homes.īy combining proven technologies, the learning curve isn’t as great a hurdle, and you remove the troublesome burden of “reinventing the wheel”. This has the added benefit of contributing food and energy to the community as well. The idea isn’t just to build a house on a piece of land, but rather a whole system whereby a reasonably sized family can live comfortably, producing their own food and energy, enabling them to become self-sufficient. ![]() Most people, if they are able to find employment, spend most of their time working just to pay bills, and can barely keep a roof over their heads and food on the table. They cannot afford to buy a home, land, and the needed technology to make themselves and their families self-sufficient. ![]() UPDATE: $25k 1280 SQFT RANCH STYLE SHIPPING CONTAINER HOMEĪll over the world people cannot afford to live sustainably, much less comfortably. An “affordable” 1500-2500 sq ft open sourced natural material home, greenhouse, 5kw wind turbine, and a 5kw solar array, for less than $100k (crowdsourced home & community building) Pilot Project: The “Off Grid Community Project” is the first stage of a multi-stage project which if successful could expand into a small self-sustaining community.Ĭoncept: Build a sustainable living self-sufficient off-the-grid home system, which anyone can build for less than $100k, and open source the plans to the world. You can list all ZFS datasets ("file systems") via zfs list, where the USED column indicates the space used by the dataset, which includes the files, child datasets and snapshots belonging to a specific dataset AVAIL indicates the remaining space in the pool, and REFER indicates the size of the files specific to this file system, i.e., not snapshots or child filesystems.OFF GRID COMMUNITY CONCEPT: SUSTAINABLE LIVING & RENEWABLE ENERGY To see the free space in pools, you can list all pools via zpool list. In Ubuntu, you can find the listed disks or partitions under /dev/disk/by-uuid/ and /dev/disk/by-partuuid/ respectively. To see how pools correspond to disks or partitions, you can use zpool status. ZFS is both a file system, a volume manager, and optionally manages RAID arrays it would be analogous to, e.g., ext4 on LVM optionally on RAID. Snapshots also fill up the pool (as part of datasets), further affecting the 'Size' df reports for an individual file system. ZFS uses one or more disks (or partitions) to store pools that can contain one or more datasets (interpreted by df as filesystems), all of which share the pool's free space. Note that df does not provide accurate values for free space in ZFS file systems. Removed files are still referenced by past snapshots, so what you describe is expected behaviour.Īs you already observed, the space remains used due to snapshots only after deleting the last snapshot that references the deleted files will the corresponding space be available again for new files.
