What Can Be Learnt From a 17th Century Town

wattle and daub wall“In Plymouth, Massachusetts — the site of the first English colony in America — Matteo Brault spends his days living a 17th century life, along with dozens of other re-enactors on the modern-day Plimoth Plantation. Brault works full-time as a 17th-century style blacksmith, using traditional tools like a grindstone, hand-made nails and a large bellows for making the fire hot enough for forging iron and steel. He also helps build the traditional shelters.”

“The simplest homes in town were built using cratchets — natural forks in trees — as support for the ridgepole of the roof. The walls are built up with “wattle” — small sticks for the lattice structure — and “daub” — a mortar of clay, earth and grasses. Instead of using the traditional English lime wash to protect the walls, the colonists took advantage of the plentiful wood in the America and created clapboard siding by cleaving wood into thin boards. For the thatch roofs, large bundles of water reed or wheat straw are woven with a giant needle by two people working in tandem (one outside and one inside). “It’s like a giant quilt made of grass,” explains Brault, “which makes a water-tight roof that essentially acts as a giant sponge. It absorbs water and laps it off.”

Human Alarm Clocks

human alarm clockI’m one of those people for whom it’s hard to get out of bed early, especially when I didn’t sleep enough. Setting an alarm clock makes little sense because I turn it off and go back to sleep. Setting multiple alarm clocks throughout the apartment might work, but it bothers the neighbours and I will still wake up too late. The only foolproof solution for me is a human alarm clock, but unfortunately this is not always available, or reliable.

Enter the professional human alarm clock, or knocker-up. Before the advent of reliable and affordable alarm clocks, British and Irish workers were woken up by a person who made sure they could get to work on time. The knocker-up used a baton to knock on clients’ doors or a long and light stick to reach windows on higher floors. Others used a pea-shooter.

knocker up with pea shooterThe knocker-up would not leave a client’s window until it was sure that the client had been awoken. People would agree verbally, in advance, or simply post a preferred time on doors or windows. There were large numbers of people carrying out the job, especially in larger industrial towns such as Manchester and London.

Generally the job was carried out by elderly men and women but sometimes police constables supplemented their pay by performing the task during early morning patrols. Larger factories and mills often employed their own knocker-ups to ensure labourers made it to work on time. The profession lasted at least until the late 1920s and in some regions until the 1950s. Bringing it back would not only make me reach early morning appointments on time. It would also create new employment, foster social cohesion, and save energy and resources.

Battery Killers: Grid-Interactive Water Heaters

grid interactive water heatersGrid-interactive water heaters (GIWHs) add bidirectional control to electric resistance water heaters, allowing a utility or third-party aggregator to rapidly toggle them off and on. This functionality turns a fleet of water heaters into a flexible energy-storage medium, capable of increasing and decreasing the load on the grid on a second-by-second basis.

GIWHs are currently the least expensive form of energy storage available. Utilities can use fleets of grid-enabled water heaters for load shifting, demand response, arbitrage, ancillary services, or to respond to unexpected grid-stabilization events. Traditional dissemination of new water heater technology has been a painstakingly slow process, but water heater rental programs may greatly accelerate this process.
