We were getting at least a small amount of generation even on cloudy days up until yesterday (2.9kWh was the lowest day). Yesterday was zero. Zero today so far. I'm wondering if something happened related to the last firmware upgrade on our PW3. It very recently went to 24.36.10 from...
Electric motors can be explosion proof but not a fan. The best you get is some degree of spark resistance; level A, B or level C. This means that the fan is built from materials which when rubbed or scraped together won’t produce a spark. Generally such a fan would have the ...
My grandparents live in a small town fifty kilometres away 【3】 Jiaxing. I spent about half an hour 【4】 (get) there. They gave me a warm welcome,and 【5】 (cook) me a big meal. We talked far into the night and they told 【6】 some happy stories about them and their neighbour...

Small electric motors are capable of providing very high peak torque and power. Thus, the ability to use a small combustion engine operating at maximum efficiency coupled with an electric motor operating at maximum efficiency offers an outstanding combination for minimizing emissions, providing excellent...
In my experience, it is common to see students experiment with small electric motors to which small propellers are attached. The propellers along with the motors are able to generate an electric current while interacting with the wind. Along with it, they manage to turn LEDs on and make small...
