Biodiesel In Cambodia

It has inspired me to get involved with renewable energy projects in Northern California and around the world. Last year, I spent seven months working on a Jatropha-to-biodiesel project in a remote village near Angkor Wat, Cambodia. Despite a rapidly growing population and an increase in foreign investment, Cambodia is still a poor country with a very undeveloped infrastructure. The typical village family relies on a single 12-volt battery to power their...

A glass-coated heat exchanger coil by Bradford White. A glass-coated heat exchanger coil by Bradford White. Nearly all tanks are tested to at least 300 psi and rated for 150 psi working pressure on the water side. The temperature and pressure-relief valve (required both by code and manufacturer's instructions) offers protection against the tank overheating or exceeding its working pressure rating. Ratings for heat exchangers have a much wider range, with some models capable of withstanding...

In some cases, the wind turbines are either remanufactured or imported. For imported models, the North American contact is listed. Rotor diameter is a typical identifier for turbines, although using the swept area would be handier. The difference between a turbine with an 8-foot diameter and one with a 10-foot diameter...

Disconnect Marking

The direct-current world of PV systems can be somewhat unfamiliar to many electrical system designers and installers, and there are sometimes details that get overlooked in designing, installing, and inspecting these systems. This Code Corner covers a few of those commonly neglected details Single-conductor, exposed cables type USE-2 or the new PV cable PV wire are used as module interconnecting cables. In each circuit, there is a need to be able to distinguish which conductor is the grounded...

Info

Autostart generators are capable of remote start, meaning that these units can be started by an external signal, such as one that might come from an inverter when it detects a set battery voltage level. The control over the generator's operation that is, when to run and when to stop is external to the generator, while the generator provides its own safety protection, such as shutoff for low oil level, overheating, and other factors. However, numerous real-world bugs can interfere with such...
