One problem is the analog radio receiver - despite various attempts, the reception from the Zürich area has failed to improve, including the last project on the Sonnenberg. Silica sand for glass in Bülach has long been promoted in Embrach, there was even a mine on the hillside to the east of the Village. The underground of Embrach is rich in gravel, a big part of it is already degraded. From the 9th century already, hydropower was used from Illinger mill. From the mid 19th century many other industry combined to make use of a large number of old water reservoirs in the valley. Today the Haumühle again turns a waterwheel. Since 2004, a small power plant on the Töss River produces power for up to 1000 people. The route Kloten - Embrach - Andelfingen was part of a medieval trade route from southern Germany. The route went from Stein am Rhein on to Stammheim, Andelfingen, Pfungen, Embrach after Kloten, thence to Baden, then to Geneva and Lyon to the fairs. The records of duty in Kloten show that the products mainly transported were wine, iron, salt, linen, fruits and spices. The path in the early maps is shown as a dirt road, noted only as a (Saumpfad) horse track.. The bridge over the Töss 1838 in Bruni, now Tössallmend Neftenbach, made this river transitional weather independent. This cleared the way for the road Pfungen - Embrach - Rorbas. A stone bridge over the river at Rorbas was built in 1840. The "Kohlenschwärze" (the slippery moist forest on the northern slope of the Blauen over the Töss River) is a geological, hydrological problem area since the Middle Ages, always leading to file entries. The road there could only be completed by 1850. Towards the south, the route Embrach - Lufingen - Kloten was built 1841 to 1850. In the north from 1842 to 1843, the road piece Rorbas - Wagenbrechi - Chrützstrass - Glattfelden was accomplished. From 1858, the route Embrach Dreispitz - Eschenberg - Bülach, with gentle climbs passable throughout the year, was finished.
