Range Hoods and Airflow Quality
David McNulty uses hoods with an airflow of 600 cfm for standard cooktops but upgrades to a 1,200-cfm hood for commercial-style ranges.

Staff Report: Blackout Power Solutions
The small, gasoline-powered portable generator is the classic ad hoc response to a major power outage. Yet it may be the homeowner's worst possible choice. Able to provide only enough output for a few lights and a refrigerator, gas-powered generators need frequent refueling and make a lot of noise. Of even more concern is the fact that in a storm situation, portable generators often kill a few people, either by carbon monoxide poisoning or by electrocution. What's more, gasoline spills occasionally cause structure fires and serious burns, and if the do-it-yourself user decides to get creative and wire the generator directly into a home circuit, a generator set can "back-feed" the utility, sending lethal voltage to utility workers repairing lines. Our Staff Report looks at the available alternatives to portable generators and guides you in selecting the right size, switch, and wiring options for your needs.
