Hollywood sets target cleaner, quieter power sources to reduce CO₂
Dangerous levels of CO₂ emissions rising on film industry sets Harmful CO₂ emitting gasoline and diesel generators have been powering movie sets for years and emitting harmful carbon dioxide (CO2). They power cameras, sound and lighting equipment, special effects rigs and basecamps all rely on these generators for power. As movie sets have grown in size and complexity, even adding advanced computing, their complexity, their carbon footprint has also grown. A large film set emits that same CO₂ as the energy needed to power 650 US homes for a year (Time Magazine). Gas and diesel powered generators are not only bad for the environment, they are also noisy, which is particularly problematic on movie sets. A single 10kW diesel generator emits about 75dB of noise—roughly the same as a leaf blower. Because of their sound and exhaust fumes, diesel power sources must be installed 1,000 feet or more from the set location. This often entails thousands of feet of power cables snaking precariously underfoot, all of which is costly to set up and maintain.

ReVolt has designed a better way to power movie sets by providing clean, mobile, always-on, and quiet electricity, with the ability to monitor power levels remotely via an app so mobile power stations can be recharged when needed. “The big thing is,” said Schwalm Who is this and he needs to be introduced?, “We're not pumping out toxic fumes, you can run our systems on interior film sets with no concern.” “Also, some camera cranes have motion control systems inside of them, and dirty power from generators often interferes with capturing dialogue clearly,” said Schwalm. “The cool thing about our unit is we deliver pure sine wave AC power to clearly capturing audio ReVolt has designed its patented power technology into an expanding fleet of portable vehicles. The smallest, the WeVolt, generates 17.5kWh capacity and 14kW output and the 8,500 pound Mule delivers 210kWh of capacity and 120kW of output power, supplying on-demand energy across 480V, 208V, 240V and 110V connections. Additionally, this technology is virtually silent to operate, emitting about as much noise as a computer fan.

High power density modules and 48V-centric power delivery transforms portable power systems
To enable a high power density power delivery network, ReVolt adopted Vicor BCM® fixed ratio bus converters and DCM™ DC-DC converters. One of the portable vehicles the “Mule” uses a BCM4414 to convert and isolate an 800V battery to create a 48V bus., An array of DCM3414’s are then used to convert and regulate the 48V bus for various 24V loads. The high-power density (770W/in3) BCM4414 has very fast transient response, which eliminates the need for a bulky 48V battery. “With one Vicor module, we can do what it would take eight components to achieve,” Schwalm said.
