How Diamond Blades Make Plowshares More Fuel-Efficient

SCIENCE! and Technology Articles on Desert Diamond Industries' BlogDiamond blades make all kinds of work easier: construction, demolition, manufacturing, metalworking, you name it. We never thought we’d see them down on the farm, though.

According to Kit Eaton at Fast Company, German scientists are developing diamond coats – well, diamond-like coatings (DLC) – for plowshares. Why? According to Keaton:

… The German researchers suggest about 50% of the energy put into the plowing process is instantly wasted in overcoming friction, and this accounts for a significant portion of the million liters of fuel the German farming industry uses up each year in working the land.

Hence the new attempt to coat the blades with DLC. This instantly reduces the plow’s friction by 50%, and can actually reduce the energy required from a tractor hauling the coated plow by over 30% compared to an uncoated plow.

Less friction means that a smaller tractor could pull a larger plow with less fuel. This means that farmers could spend less fuel and time plowing larger fields, which in turn could lead to lower food prices. Heady stuff.
