This animation describes how water could be used as a level during the shaping process of the blocks, used in the construction of the Giza Pyramid. The second video below shows the entire building process.

Open house day at Bio Veda Academy – 03/03/2018
Take a tour of Bioveda’s Urban Garden in South Africa. This whirlwind 46 minute home tour shows Bioveda’s earthbag and aircrete structures, their appropriate technology such as solar cookers and biogas, as well as an extensive system of earthbag planters, wetlands and water filtration. They reuse all their water seven times. There are some audio glitches, but the information presented is excellent so please overlook the minor flaws.
Aircrete Lightweight Bricks and Blocks
We discourage using lots of cement because of its adverse environmental impact. However, there are times when it makes sense. For instance, concrete is very useful for making strong bond beams and water resistance structures in rainy climates. Foamed or lightweight concrete such as aircrete has become very popular lately because its lighter weight reduces labor and improves the insulation value. Bricks and blocks are the defacto international building unit, so I did a search for “aircrete blocks” and found the Forterra company in the UK, who is a major supplier of these green building blocks. Their products are profiled below.
Affordable Green Transport Options – Taxi Apps and E-bikes
Some of the greenest, most affordable transport options are now appearing in countries such as India and Cambodia. Uber has finally arrived in Cambodia, but the local alternatives are better established and often less expensive. PassApp Taxis, Exnet Taxi, and iTsumo are Uber-like taxi apps operating in Phnom Penh that allow you to book a metered tuk tuk, taxi, or SUV with the touch of a button (theoretically).

Artist Creates The Most Unique Tiny House Ever Built
I have seen and toured many tiny homes over the years. However, this is honestly the most unique tiny house I have ever seen. My only regret is that I did not ask how many hours he has into building this tiny house.
