Please note what I was saying (and not saying). I was NOT saying that within some "normal" range of wind speeds a varying load could not be used to control turbine speed. I was saying that could not be the ultimate control because the necessary size of the power load is increasing exponent...

My understanding from backalong was that one needs to feed the turbine into a battery in order to provide a load to prevent overspeed and to stabalise the voltage as this can vary a huge amount. Need to check. With the batt you then have the freedom to do whatever you fancy. If you think you might ...

285Wp per panel is miniscule by todays standards! I've seen 750Wp and higher! Uh..... what size panels? That 285 w/panel was good THEN but yes, they have gotten better. I believe THAT SIZE panel now should be maybe 320 watta to be considered good. There are larger panels made, but these are the sta...

:roll: I should have asked "system size". Thanks for the lesson. :D 24 panels (back then, about 285 watts/panel pretty standard) They are on the roof of the barn/garage, across a drive (that is a "right of way"). So on a separate meter from the house with production from the sol...

Good news, great warranty support. What is peak for you Mike? Can do a lot with 2kW when set up correctly for it's efficient use. System rated 6.8 KW That would be around noon in the summer (when aligned perpendicular to the suns rays)/ But peak power is not a useful measure of solar power. Energy ...

Back in production (hopefully) While we were out shopping the Solar Store called to ask if OK they came out to install the replacement inverter. Our grandson told the sure. So we got home as they were [putting it in. Not even a rebuilt one of the model that died under warranty but their newest. Too ...

Well, they ALL produce the same CO 2 to C 2 H 5 OH ratio (in breaking down C 6 H 12 O 6 ). C 6 H 12 O 6 =>2(C 2 H 5 OH) +2(CO 2 ) If you like, YOU try to find some other result such that the number of C, H, and O atoms are the same on both sides of the chemical equation. Note however that yeasts ar...

Bread yeasts that come fresh are like beer yeasts, aka "top yeasts" and are optimised for producing gas to blow up the bread asap. They may well be top-fermenters too, which would make sense as they are happy in an aerated medium, when all yeasts concentrate on magnifying their numbers an...

Didn't,t have any wine yeast so used a mixture of bread yeast and saved beer dregs from my other post on beer yeast. Already starting to glug through air locks. Bread yeasts that come fresh are like beer yeasts, aka "top yeasts" For wine your really want wine yeast (bottom yeast). But use...

https://www.pv-magazine.com/2025/05/20/ikea-begins-offering-air-to-water-heat-pumps-in-germany/ Remember, touting high CoP when only one of the temperatures is specified is meaningless. So it's an immediate red flag for me when what is essentially an "ad" just gives one temp (not even say...
