Re: Wind and Solar vs Coal, Gasoline, Nuclear

How exactly do you believe we have “measured” those Co2 levels ...or the rate of change ? Science. ... remember, we have only been able to accurately measure atmospheric CO2 since the 1950’s And we can use the same measurements on air entrapped in ice cores going back thousands of years. Odd ?... i...

Nope. Those cans are already as thin as humanly possible; any deep scratches and they will be very close to failure/leaking.

Do something like Steve Roberts did. Build a two wheel bike like normal. Then have outrigger wheels you can drop when you need more stability.

Re: Build a mini USV/UPS

Feeding the devices and the BMS with the same power line at the same time shouldn't cause any issues i guess, as it's a common charge and discharge port. This works as long as the current from the supply is limited to under the max charge rate of the battery, and as long as the load can operate at ...

I'm with your arguements, but your heavily exaggerating. It's really not the case that batteries will just fail from one day to the other just because they are kept in a charged state. They will loose capacity. Right. And you will never see the gradual decline until you need it one day - and it won...

Granted, it's pretty quiet as it is, but of course we have to pursue perfection for some stupid reason, right? Why would that make it quieter? Statorade fills in a little bit of the area between stator and rotor, but those aren't structures that touch anyway. And there's not enough to damp resonanc...

I get 200w average, assuming 8mph wind average.

Tower minimum height is going to be 12.5 meters plus the height of the tallest object within 200 meters of the turbine.
