Paul Wheaton continues talking with Anna Birkas about Natural Swimming Pools, the subject and the DVD. They talk about vertical walls, pond liners, and Sepp Holzer's approach of compressing the soil like a pig would in order to seal a pond. Paul asks about the possibility of using rammed earth as pool walls. They talk about cement, and possible cement toxicity, such as radon or petroleum. They talk about Steve Heckeroth, who has built a very large natural swimming pool. Paul shares his enthusiasm for Steve's 45 horsepower solar electric tractor. Paul suggests that plants will come into the system on their own, without planting them. Anna talks about Michael Littlewood's books, and how they might help in making natural swimming pools.
