How about a multipurpose, easily transportable, nearly always ready to go 3-5kW generator? 40 hour runtime at 1000 watt load. http://priups.com/ http://priuschat.com/threads/prius-as-a-generator-revisited.39613/ http://priuschat.com/threads/priups-using-the-prius-as-a-backup-generator.12430/ You can get some nice impressive runtimes with this option. These projected runtimes are based on measured fuel consumption at various loads. The second link above contains the same table in case this gets mangled in transit. kwh/month | Idle | User | Total | Tank | Runtime | Burnrate | Real kwh | Real | User kwh | User Load =avg base | Load | Load | Load | (gal) | (hrs) | gal/hr | Produced | Efficiency | Produced | Efficiency load | watts| watts| watts | | | | | | | 72 315.8 100 416 10 126.58 0.079 52.632 0.15949 12.658 0.038 180 315.8 250 566 10 93.02 0.108 52.632 0.15949 23.256 0.070 360 315.8 500 816 10 64.52 0.155 52.632 0.15949 32.258 0.098 540 315.8 750 1066 10 49.38 0.203 52.632 0.15949 37.037 0.112 720 315.8 1000 1316 10 40.00 0.250 52.632 0.15949 40.000 0.121 1080 315.8 1500 1816 10 28.99 0.345 52.632 0.15949 43.478 0.132 1440 315.8 2000 2316 10 22.73 0.440 52.632 0.15949 45.455 0.138 1800 315.8 2500 2816 10 18.69 0.535 52.632 0.15949 46.729 0.142 2160 315.8 3000 3316 10 15.87 0.630 52.632 0.15949 47.619 0.144 2520 315.8 3500 3816 10 13.79 0.725 52.632 0.15949 48.276 0.146 2880 315.8 4000 4316 10 12.20 0.820 52.632 0.15949 48.780 0.148 3240 315.8 4500 4816 10 10.93 0.915 52.632 0.15949 49.180 0.149 3600 315.8 5000 5316 10 9.90 1.010 52.632 0.15949 49.505 0.150 3960 315.8 5500 5816 10 9.05 1.105 52.632 0.15949 49.774 0.151 7200 315.8 10000 10316 10 5.10 1.960 52.632 0.15949 51.020 0.155 On Jun 22 2013, Ryan Coleman wrote: >IDK, that's not a lot of juice on that, Brian... > >What's the VAC rating of your UPS?
