The 10-kilowatt-hour option was marketed as a backup power supply capable of 500 cycles, at a price to installers of $3,500. Tesla was angling to sell the battery to consumers that want peace of mind in the event the grid goes down, like during another Superstorm Sandy.
Plenty of exercise and pasture time, not much just bored, stand-around time in their stalls. With boards being rough-cut, you have thicker boards, closer to actual dimensions of original 2 x 6 or whatever size you order. Planing board smooth, takes off more wood, board is not as strong. Horse kick is quite strong, you want thick heavy boards to take the punishment. We use white oak, harder then the red oak, also available locally. We got our oak boards green from the lumber mill, used galvanized nails to put the boards up.
Be careful to apply the proper depth of sand. With its deep, loose traction, sand deeper than 6 inches is stressful to horse tendons. Start with about 2 inches and add a Â½ inch at a time as necessary. (Start with only 1Â½ inches for arenas used primarily for driving horses.) Newly laid sand contains air pockets that absorb shock and rebounds.
