Highway to hell?

An enthusiast in the US has built a motorised coffin on wheels, powered by a pulse jet. Its builder, Bob Maddox, has a strong interest in improbable vehicles and built the vehicle using a coffin and a small pulse jet, all mounted on a lightweight chassis and wheels. Weighing just 136kg, his Maddoxjets Coffin Car can accelerate from 0-100km/h in around nine seconds. According to Maddox, he once drove the Coffin Car at 100km/h but was concerned for its stability and wary of attempting to drive it any quicker.

An enthusiast in the US has built a motorised coffin on wheels, powered by a pulse jet.

According to Maddox, he once drove the Coffin Car at 100km/h but was concerned for its stability and wary of attempting to drive it any quicker. Presumably he was unwilling to end up in a coffin, in the ground. Maddox previously built a motorcycle powered by a similar pulse jet, although like the Coffin Car this was strictly for demonstrations and drag racing events and not road legal. Pulse jets were used to power the German V1 flying bombs used in WWII and are simple in design, but their hot exhaust gases mean these engines are unsuited to use on road.

    A variety of systems are available for quickly and efficiently removing water from roads as Patrick Smith reports The presence of water in a highway layer reduces the bearing capacity of the road, and in doing so it also reduces the structure's lifetime. Indeed, the recent extremely cold winter in many parts of Europe has shown that in colder climates there is a risk of frost damage when water is present resulting in costly potholes, so drainage systems performing properly are important in road design.

    Upgrading a key route through Florida – novel construction techniques are helping widen a road in difficult geological conditions – Lucio Garofalo reports. A major road widening project underway in Florida is due for completion soon. The work will improve an important section of road, reducing congestion at peak period and cutting travel times for drivers. The US 331/SR83 highway runs for some 79km and provides an important link in Florida’s Panhandle area, as it connects with Route 98.
