cant do that still working on my lib...
testing bits though:

#include "C:/projects/physical_quantities/pqs.hpp"
#include "Scalar.h"
using namespace physical_quantities;
class Rotor{
 Scalar<double> m_cl;
 Scalar<double> m_tsr;
 Scalar<q_length::mm> m_rotor_diameter;
 Scalar<q_length::mm> m_hub_diameter;
 Scalar<q_velocity::m_div_s> m_windspeed;
 Scalar<q_power::W> m_power_output;
 Scalar<int> m_num_blades;
 Scalar<double> m_rpm;
    Scalar<double> m_ellipticality;
    Scalar<q_mass::kg> m_mass;
    Scalar<q_length::mm> m_moment;

... hows that? I've shown you mine... now show me yours
or anything equivalent will do

zero runtime initialisation cost is Fact with my lib now.
