Great idea. Getting tied into the grid seems to be an important factor here. Saves the whole problem of storage. The perspiration will probably pay for itself in time, since the foundation is the least likely part of this power plant to fail over time.
This interesting case study spotlights the old rule that most great engineering efforts are 80% perspiration (actually, I think it's 90%) and 20% technical smarts. This project simply wouldn't have happened without all that digging, building, and dirt moving.
Industrial workplaces are governed by OSHA rules, but this isn’t to say that rules are always followed. While injuries happen on production floors for a variety of reasons, of the top 10 OSHA rules that are most often ignored in industrial settings, two directly involve machine design: lockout/tagout procedures (LO/TO) and machine guarding.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
