Isn't flour explosive in certain concentrations? I think cornflour is
anyway. Couldn't we develop an internal combustion engine using powdered
fuel, or would the energy needed to grow and produce such fuel be
greater than that contained in the fuel?

Hypothyroidism is a seriously debilitating condition with an insidious
onset.
Although common it frequently goes undiagnosed.

Early diesel engines were developed to run on coal dust

"The first experimental engine was built in 1893 and used high pressure
air to blast the coal dust into the combustion chamber. While the
prototype blew its cylinder head off but, four years later, Diesel
produced a reasonably reliable engine. His ideas for an engine where the
combustion would be carried out within the cylinder were published in
1893, one year after he applied for his first patent."

Yep, there have been some nasty explosions in the past.


Ask Mr Diesel, IIRC he was working on an IC engine to run on powdered
coal.
