What devices do you have there now developing? Tell me again. For example, because the measurement of precipitation measurement. Yes, .. devices for radiation measurement, but the but it has already given .. I can remember, since you have developed a special device, how to automatically measure the amount of water, but not the "Picha-Evaporimeter" but that with the capacitor. How has he does it work? Yes, that was - that is likely to function today. Yes. How did that work? That is - it's a - it must be a dielectric, by the - so that means a vessel and the vessel is out there - even dielectric. And, with two electrodes - one inside, one outside. And I have made of aluminum foil and had the so-coated from outside and from inside and the - no, not from inside but from the inside had been water. And depending on how high the water level was above you can see that. But I am here later had the idea when I make electrodes, which take the water directly - ie needles and so on-so I can measure with a lake - the water at the lake, the lake Piburger for example. And it did not rain was long and already I've had the display, it had increased the water by a millimeter or so.
