At the same time fund research into ways to do recycling that is more cost efficient and more environmental friendly with regard to chemicals used, etc.   Then once you have better tech for a certain class of garbage, go process it in bulk.&lt;p&gt;Of course humans being humans, we&amp;#x27;d probably not bother to fund the research, not do upkeep on the encapsulation material and mess up the ground water, etc.   Still interesting to think about just having one or two national trash dumps.</text><parent_chain><item><author>runako</author><text>I enjoy seeing land use comparisons.

Most residential homes can install it on their roof and this also applies to flat industrial building which do not consume a lot of energy. This also makes your solar production decentralized.</text><parent_chain><item><author>runako</author><text>I enjoy seeing land use comparisons.
