Comments Off on First Hybrid Street Sweeper Cleans Up NYC

The world’s first hybrid street sweeper has begun cleaning the streets of New York City.  The Allianz 4000 is a diesel hybrid that reduces diesel fuel use by 40 – 45 percent compared to traditional street sweepers. The Allianz 4000 also features two 12v lithium-ion batteries and an electric traction drive system which, in addition to the diesel engine, both propel the truck and spin the broom at a constant speed.  The sweeper has a top speed of 60 mph so it can travel on highways, but whie on duty it usually runs at about 3 – 7 mph. The benefits to the hybrid street sweeper are both the huge fuel savings and the lower emissions that easily fit under any city-wide laws requiring cuts in fleet emissions

Comments Off on Portable Solar Power Plant, Water Purifier and Fuel Cell in One

In many areas of the world, and also during times of natural disasters, clean drinking water and access to power are scarce.  The company The Essential Element has designed the Hydra water purifier and fuel cell to take care of both of those problems at once. The Hydra is equipped with a 2.88 kW solar panel array that runs a pump that pushes water through a self-cleaning filtration device (capable of purifying 87,000 liters a day), juices up lead-acid gel batteries and runs an electrolyzer that splits some of that water to fill a .37 cubic-meter tank with pressurized hydrogen

Comments Off on Port of Long Beach Retrofitting Old Tugboats

After debuting the world’s first hybrid tugboat in 2009 , the Port of Long Beach is partnering again with Foss Maritime Company to retrofit an existing tugboat with hybrid technology. The ship called the Campbell Foss is a conventional dolphin tugboat assisting ships in the San Pedro Bay. It will be fitted with motor generators, batteries and control systems by Foss at one of their shipyards.  The retrofit should cut 1,340 tons of CO2 emissions and save 100,000 gallons of fuel per year.  Foss and the Port plan to introduce more hybrid tugs over the coming years and see more retrofits in the future.
