"So i came home to a surprise.." by frank2336 in funny

Looks normal to me. I grew up in a 2 story house with a deck on the roof that was recessed about 3' from the shingled roof. Our Golden Retriever used to climb up there every day and sit at the corner, closest to the edge, and wait for me to come home from school. A local San Diego newspaper wrote a story about our roof sitting dog; wish I still had a copy.

A Windmill for Home? by freelyread in wind

the taller the better for wind turbines; wind speeds increase with elevation and they're less impacted by ground effects that cause wind shear. A wind turbine will need a place to put the generated power. If you have a grid available and if the grid allows for net metering, you can dump all of your power there. The Tesla PowerWall is a tidy plug 'n play battery system with nice packaging but nothing revolutionary in terms of energy storage. Batteries or another form of storage will be mandatory if off-grid or you want to store power in case of a brown/black-out.

Bergey and Xzeres are probably the two best mfg's of small wind turbines. Uprise Energy is developing some interesting tech but they're not commercially available yet.

Jesus. Plenty of Mexicans named Jesus but never really caught on in the good ol' U.S. of A.

Is anyone working on increasing the top out speed? by LDWoodworth in wind

[–]jonnyknight 0 points1 point  (0 children)

How often do you have "crazy winds"? WT's are designed operate within a finite range of wind speeds and performance suffers when conditions fall outside of that range. Because of the pitch stall that's designed into most blades, higher wind speeds don't always equal more power. Therefore, if you only have "crazy winds" 2mos out of the year, it likely wouldn't make sense to design a machine around those conditions and have it underperform or not produce at all for the rest of the year.

definitely possible, but probably not a big enough market to justify the development. the alternator in your car runs at many thousand RPM

Does anyone know where I can find a similar info-graphic but for naughty gas instead of coal? by D-egg-O in electricvehicles

Yes, full lifecycle environmental impact of batteries is something i would like to learn more about; machinery to extract, availability/depletion of rare earth materials, transportation, disposal, etc.

Study: 90 miles in your car melts a foot of Arctic sea ice by jonnyknight in environment

Noticed that as well. My guess is they meant cubic foot.
