People in Aust are complaining about the cost per kW of proposed nuclear, and trying to say how impractical it is on that alone, without even realising how much these things cost without HEAVY government subsidy.

Scaling this up a lot would require increased V production. The good news is that there are about 38x10^6 metric tons of minable V. http://minerals.usgs.gov/minerals/pubs/commodity/vanadium/vanadmcs05.pdf . Quote:

In this way the operator can guarantee steady output and add value as a grid frequency stabiliser. Additionally the VRB system power can be sold as spinning reserve which attract a large price premium and could make the whole wind/storage system more economically viable even with the higher initial price.

I hope to have a better explanation in my Clean Break column on Monday.

Wind farms usually cost about $1.10 per watt, so this increases the cost by about 80%. Is this at an economic cost yet? $6.3M for a 7MW windfarm means $.90 per watt.
