	- Thanks, Dorkmo. We already incorporate a buck converter in the design, have a look at the [[TiVA]] electronics. Additionally, the coil layout is switched from serial to parallel at higher rpm. The latter will give a much better electrical efficiency than any buck or boost converter. However, the concept is entirely new and the hard- and software will have to be developed. --[[User:Alex Shure\|Alex Shure]] 20:10, 11 April 2012 (CEST)

 Both VAWT & HAWT are on poles or towers that you have to avoid running into with the tractor. But that is more of a secondary question where you put them and not the construction the thing we are trying to do here first. Just make room for a tractor to pass between them and you are done. It is dependent on where you are so I wonder if you have this problem or if you try hard to think of problems that do not exist yet. In that case take a look at the tasks that need help and do something more constructive instead.
 Regarding cost it will be interesting to see what we come up with. If we don't reach the goal we can hopefully improve. That is what this is about./Johan

Several issues withn small size VAWT haven't been mentioned yet:

The power output per square meter wind farm may be higher for small VAWTs, but the disadvantage is, they use the area exclusively. With large HAWTs spaced 400ft apart, the area can be used for farming with a minimum area lost for wind power, VAWT spaced at 20 ft don't allow any use.

Higher weight per power (kg/kW) means also higher costs per kW as materials don't come for free.

In the OSE wiki I found some requirements for wind turbines:
<<<Low-cost - must cost less than $1 per installed watt and $0.05/kWh produced on a medium speed site (6m/s average speed [13.4mph, 21.6km/h])
>>>
I am very curious if its possible to achieve this goal with small turbines.
