biomechanical energy harvesting: "a knee-brace-like gadget developed by a Canadian scientist harnesses the power of the human gait, generating enough wattage from your daily walking to power a cellphone or two-way radio and then some."
gallons per mile: researchers discovered that this (specifically, gallons per 10,000 miles) would be a more effective unit of measurement than miles per gallon, "which significantly underestimate the gains in fuel efficiency that can be achieved by trading in very low m.p.g. vehicles. That's because the real significance of differences in m.p.g. is often counterintuitive. The jump from 10 to 20 m.p.g., for example, saves more gas than the one from 20 to 40 m.p.g. The move from 10 to 11 m.p.g. can save nearly as much as the leap from 33 to 50 m.p.g." The Energy Department and Environmental Protection Agency Web site fueleconomy.gov already offers a conversion calculator.
minicattle: some 42 inches high and weigh about half as much as regular cattle, smaller cows "consume a third as much feed, but they still manage to produce more than half as much meat. 'The productivity per acre is at least twice as much as large animals,' says Richard Gradwohl, a retired business professor."
