One way to conserve energy and resources is to fix things that break rather than throwing them away. The Devcon Corporation makes a wide variety of products that can solve some very nasty repair problems as well as increasing the life of various hardware. Typical are Plastic Steel and Plastic Aluminum. A far cry from their sissy hardware store counterparts, they are super strong and you can (for instance) repair engine blocks. Devcon makes a paint called “Z” that actually outperforms hot dip galvanizing (Milspec, no less). Devcon Rubber repairs split rubber boots better than anything else I’ve seen. They make a wear-resistant self-lubricating epoxy compound that can be used to make long-wearing bearing surfaces in wood. (It can also be used to build up worn shafts.) The list goes on.
