If the hill is too steep/long add electric motor hubs to the bikes.

I would say the exhaust fan if it went out within one year of them being there you probably want to replace the motor.

The zoning is done with motorized dampers, one on each outlet from the plenum.

I own a local Carwash and a manufacturing and e-commerce store for LS motor racing parts.

So I’m my opinion she isn’t motorizing anything just a blank page.

We updated nearly the entire house: - installed new lighting- updated bathrooms with new fixtures and a fresh coat of paint- Partially painted exterior (brick) and modernized architectural features with new wood- Added 8 ft Privacy fence with a motorized gate to provide access to the garageWhat was the outcome?

Who knows when the blower motor in the HVAC will burn up or if a kid mowing the lawn hit the condenser hard enough to crack a joint in the line, pressure drops and causes damage?

It's good that many areas have the alternative for families to choose Charter Schools.Way past time to bring back Woodshop, Home Economics, and Motor Shop.Add to these other options like you mention..... 

A recent example is this winter the blower motor and control board on the furnace went out, they sent a technician next day they replaced the board and motor for 75 dollars. that service would have been almost 1000 dollars, seems like a good deal.
