The most promising way of its detection is measuring the feeble ``neutrino wind'' forces exerted on macroscopic targets. The expected acceleration is $\\sim 10^{-23} cm/s^2$ for Dirac neutrinos with a local number density $\\sim 10^7/cm^3$. A novel torsion balance design is presented, which addresses the sensitivity-limiting factors of existing balances, such as seismic and thermal noise, and angular readout resolution and stability.","authors_text":"C.
