# Hybrid Helicopters Patented System Controls Energy Flows for Optimal Efficiency By Katie Cordrey | Published 2010-06-14 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/hybrid-helicopter References: [favstocks](http://www.favstocks.com/eads-to-showcase-hybrid-helicopter-and-algal-aviation-fuel-at-2010-ila-berlin-airshow/0516512/) & [classic.eads.net](http://classic.eads.net/1024/en/pressdb/pressdb/20100608_eads_iw_ila_hybridheli.html) The [European Aeronautic Defence and Space Company](https://www.trendhunter.com/trends/credit-facility) (EADS) presented a full-size hybrid helicopter concept model and aviation biofuel made from algae at the June 8-13, 2010 ILA Berlin Airshow. The patented diesel-hybrid system employs multiple diesel-electric motor generator units in combination with batteries and power electronics to control energy flows for optimal efficiency. The end result is a proprietary hybrid helicopter that produces up to 50 percent less emissions and has lower noise levels and improved safety features.
