mechanical energy from solar hot water? from a bicycle?

is there any mechanical solar heat-powered blender or low-energy high-power appliance on market?

If you can use hot water to turn a turbine to then turn into electricity (at scale, in a power plant), can you use on a smaller scale to operate a drill? a blender? anything that used to be powered by a water wheel?

(the hangup for off-grid is not the energy these appliances use but the startup power needed, I gather, the jolt of ?voltage? at the moment they start up.  I recently heard in a podcast that the grid supplies your home with 45kws of startup power, a crazy high amount way higher than what you'd ever actually use even if you were to turn all your appliances up to an 11).  That's for the startup jolt solely.  

How about any blenders or drills operated by a bicycle? effective nut shellers?

A lot of this stuff is covered in early Mother Earth publications.
Stirling engines may work with hot water.
Today though we can use a variety of power sources, you just need to look widely, its nearly all been done before.

Before transforming solar heat into electricity (which can be done with stirling motors, not that efficient, and expensive), why not directly use solar for electricity?
