Solar Impulse 2 – Largest Solar Aircraft Ever Made (w/videos)

Solar Impulse 2, unveiled in April, is the largest electric aircraft with a wingspan of 72 m.

And because its wings are covered with 17,248 photovoltaic cells, which is enough to fly at daytime and accumulate energy for the whole night, it could theoretically stay in the air forever. This is important because the team behind the project would like to fly around the world without landing.

This two-seater weights 2,300 kg (5,070 lbs), from which 633 kg is battery pack weight. We believe that total capacity of the battery pack is well over 100 kWh.

Four motors propel the Solar Impulse 2, each of 17.5 HP or about 13 kW for total 50 kW output, to speed of up to 90 km/h (56 mph).

While the around the world trip is scheduled for 2015, SI2 already has its maiden flight behind it in June:

Energy density of the used KOKAM cells ist 260wh/kg due to a new electrolyt. Doing the maths means they have 164 kwh on board. In other words double of Model S Capacity by same weight – battery Evolution! I found some interesting battery News on the solar Impulse Website “Even batteries prefer warm temperatures” “I’ve always associated batteries to an expensive tool that I never have at hand when needed (usually realizing I’m out of stock when the stores are closed). The fact that most modern-day electronics (cellphones, mp3 players) can now be charged through a laptop, has been such a liberation. But although standard AAA or AA’s are being used less by the average consumer, the utility of this special energy storing device is expanding in many other areas. Think about the automotive sector and hybrid or electric cars; or maybe about our inseparable friend, the laptop, to name a couple. This type of battery is the so-called secondary battery (rechargeable) to be used multiple times and the kind that is sparking the interest of large chemical companies because of their potential to resolve our dependency on fossil fuels. What is so particular about Solar Impulse’s batteries is their… Read more »
