The Role of Carbon in the Soil with Rattan Lal
http://www.youtube.com/watch?v=N7QuG7NmCbc


John Kempf interviews Dr. Rattan Lal, an acclaimed soil scientist, researcher, and author. In the early 1990s, Dr. Lal was a pioneer of the now-mainstream idea that healthy soils are a defense against rising levels of carbon dioxide in the atmosphere.

This episode is densely packed with information about soil health and how to achieve it, not only for farmers but also for policymakers and educators. As Dr. Lal says in his closing remarks, "Agriculture, if done properly, has to be a solution to environmental issues.”

KEB: větrák co dáš na zahradu bude mít CF ještě nižší než FVE a výkon 200W :D

PAD: jeste k tem ostrovnim systemum - smysl mi to dava samozrejme offgrid a/nebo kdyz chces poslat CEZ do prdele:)

TADEAS: Ja si to jen tak pronasobil v hlave - bez dotaci stoji 4.13kWp FVE asi 175kkc. Tato elektrarna by mi dala v prumeru ~4kWh za den listopad - unor (spise vice, https://re.jrc.ec.europa.eu/pvg_tools/en/tools.html#PVP ). Takze kdybych vzal ten nejnepriznivejsi pripad lednovych mrazu, kdy (v mem pripade) je treba dodat asi 32kWh (do topne tyce v aku nadrzi), tak bych proste potreboval tech elektraren 8, coz je cca 54k EUR. Tohle je ten nejblbejsi pripad, u ktereho jsem skoncil s premyslenim, protoze

a) kdybych to uvazoval realneji, tak nebudu palit elektrinu primo, ale v nejakem cerpadle, ktere by tu spotrebu snizilo na rekneme 30%
b) ekonomika by u FVE vychazela lepe, protoze ty prebytky v obdobi brezen-rijen bych mohl zuzitkovat

Musim ale rict, ze ani s FVE ani s tepelnym cerpadlem nemam primou zkusenost - nejdrive jsem to porovnaval s tim, co pouzivam (drevo) a tam ta ekonomika je jeste uplne nekde jinde.

Ja to nehejtuju, me se to libi, jenom si myslim, ze v porovnani s jinymi technologiemi to nedava smysl a bez dotaci uz vubec ne. A nejsem si jisty, ze ty ostrovni systemy davaji celkove moc smysl. Myslim, ze prave na to sezonni ukladani bude davat vetsi smysl to trochu centralizovat (treba pro kazdou vesnici nebo region), kde by se prave ukladaly prebytky z FVE.

Siemens Gamesa 14 MW Turbine to Make European Debut Offshore UK

Siemens Gamesa has signed a preferred supplier agreement with innogy to deliver 100 of its new SG 14-222 DD turbines for the Sofia offshore wind project in the UK.
The Sofia project will, therefore, be the first European project to install the 14 MW model that will be market-ready by 2024, on time for installation at the site 195km from the UK coast on Dogger Bank.
Construction of the wind farm is due to begin onshore at its Teesside converter station site in early 2021, with offshore construction expected to kick off in 2023.
“The selection of these state-of-the-art offshore wind turbines for Sofia, our largest offshore wind development project, reflects our ambition to strive for continuous innovation,” said Sven Utermöhlen, Senior Vice President Renewables Operations Offshore at innogy.
“Siemens Gamesa’s towering 14 MW machine is a perfect match for our flagship Sofia project, together cementing offshore wind‘s central role in the world’s clean energy future. This turbine embodies the impressive technology we need to build our ground-breaking project, that is further from shore and more technically challenging than any of its predecessors.”

DZODZO: a co koupit větrák? Na doplnění by stačil malý scény šly taky dolů. Nebylo by to řešení? Ten totiž může tocit v i noci :-)
