In Switzerland, following the successful trans-America flight of the Solar Impulse HB-SIA, the Swiss team is building the larger HB-SIB incorporating a 236 ft span wing with 17 000 instead of 12 000 solar cells, and batteries with a specific energy increased from 240 to 260 watt-hours per kilogram. A roomier cockpit with provision for more food and oxygen plus special provision for sleeping will permit flight periods of five-days length. The round-the-world attempt is due to start in March 2015
