	To overcome the intermittency of wind, an alternative VAWT design may be a non-electric, purely mechanical water lifting device (see [http://www.alanswebsite.co.uk/vawt.html example]). The water released from the reservoir can then power an electric generator whenever needed. Other mechanical power inputs can also be used to add water to the same reservoir (e.g. see [[Stirling Engine]] video from Tamera community where solar heat runs a water pump). The power of multiple wind turbines can easily be combined for more power output. The design is flexible and multiple different generators can be hooked up. The reservoir has obvious dual uses, such as for gravity-fed irrigation or possibly even in aquaculture.

			*Good analysis. Conclusion is that the VAWT may be better in low wind conditions. Surprisingly, this piece also indicates that lower maintenance will not be a greater advantage because of lower electrical production. [http://www.wind-works.org/cms/index.php?id=64&tx_ttnews%5Btt_news%5D=2220&cHash=b55932dfebd049ab01c1d968670afc1e]. OSE analysis - if DIY cost levels are attained, then lower installation costs allow low wind areas to be tapped - poor wind resource areas are at an advantage. Moreover, if we assume that VAWTS con be lower technology - then VAWTS can attain better cost performance under the condition that the sole cost of an install is materials. This argument may change with a hydraulic drive train wind turbine, where the HAWT may be a clear winner. Material costs and output calculations can provide the solution.

For average 6.5 m/s wind in Maysville, MO - power production is 4 kW for 8760 hours - or 35 MW hours! At 10 cents per kWhr - 35,000 kWhr is $3500 worth of electricity.
