The standard Big-Bang theory predicts a cosmic neutrino background with an average number density of ∼ 100/cm3 per flavor. The most promising way of its detection is measuring the feeble ``neutrino wind'' forces exerted on macroscopic targets. The expected acceleration is ∼ 10-23 cm/s2 for Dirac neutrinos with a local number density ∼ 107/cm3. 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.
