Survey most common validation datasets for VATs

Related to #30. This might also include the fact that one dataset from Sandia was used to optimize (?) the Sheldahl and Klimas static foil data for VAWTs. @wosnik probably understood this better than I did when we read it in Sheldahl and Klimas (1981).

Should also explain why these may or may not be the greatest for MHK applications (rotor designs are different, but how, fundamentally?).

• Antheame et al. (2008) -- Sheldahl et al. (1977) data from 5 m Darrieus turbine with NACA 0012 blades. 0.08 or so c/R ratio.
• Amet et al. (2009) -- 3 datasets, from which forces were taken by Laneville and Vitecoq (1986), for a 2-straight-bladed turbine at $Re_c = 3.8 \times 10^4$.
• Joo et al. (2015) -- Use Howell et al. (2010) data, which had c/R = 0.33.
• Liu et al. (1992) -- Used Sandia 34 m data but don't cite anything.
• Murray and Barone (2011) -- Used Sandia 34 m (Ashwill (1992)) and VAWT 850 (Mays et al. (1990)), which has a "10% solidity." c/R was only 0.05 though.
• Roh and Kang (2013) -- Sandia 2 m NACA 0012 Darrieus tests in Blackwell et al. (1976), which all have c/R < 0.1.
• Ponta and Jacovis (2001) use the Strickland (1981) tow tank data, which was for c/R = 0.15. That is a common dataset.
• Scheurich et al. (2011) -- Strickland (1981) blade force data.
• Scheurich and Brown (2011) -- Penna (2008) helical data from an NRC report that I can't find. Turbine is a Quiet Revolution QR5, which looks to be fairly low solidity.
• Paraschivoiu (1988) -- Sandia 17 m Darrieus data from Worstell (1978).
• Orlandi et al. (2015) -- Sandia 17 m and Mertens (2002) H-Darrieus in skew.
