Ben, you are right. *if* you can find a 6:1 rear end
(the highest that my vehicle can be equipped with is 4.2:1)
then at 12.65 MPH the drive shaft is doing 1000 RPM.
Just a random data point: my previous truck (S10) when doing
a constant 55 MPH on level road, no wind, consumed 15 kW to

I've posted about the U.S. Government's push for V2G, and we all know of
CARB regulations making it painful for Automakers if they do not make an
effort to get credits so they can sell their profitable ice. But there are
likely items plugin-makers could design-in to increase plugin sales.

I have the Ryobi Electric Leaf Blower and bought it along with a weed
wacker, hedge trimmer and chainsaw that all use the same battery .
To turn this around keep it on topic I was thinking when purchasing
them that their 44V Lithium battery could be used for an electric
bicycle. With all these to
I'm not sure if I posted this to the EVDL already, but I bought a Ryobi
40 volt lawn mower and used (shared actually) the battery for my
electric bicycle.

IIRC,
Yep, areo drag is proportional to square of the speed:
1/2 * Cd * A * air density * speed^2
where
Cd == drag coefficient (you can look this up for many car models)
A == frontal area: the area of the vehicle as viewed in 2D from the
front, in meters^2
air density = roughly 1.2 kg/m^3 at standa
There is no issue here.
The OP brought up the continuous rating of the motor at certain RPM,
which just says something about the ability to sustain a certain current
at a certain speed indefinitely, but which does NOT limit the motor to

Notably, the most popular Solar inverter (which I have installed several
times at homes in the neighborhood) is the 2.5 kW SMA Sunnyboy.
Reason it is so popular is not only because it is an efficient
