what would happen if a 24volt 1000mA power supply was used to power a
18v device

What current range is needed by the device at 18VDC? This is important to
know.
Don't connect gismo before you have regulated the 24VDC to 18VDC with a
proprietary 3-pin chip attached to a heatsink as necessary.

Anywhere from nothing, to apparently normal operation, to
destruction of either the supply or the device or both.

The supply may have internal protection (to protect itself)
and shut down without damage, so it appears as if nothing
happens; the device may have internal regulation, so operation
appears normal (but excess heat will be produced which
can bring about eventual failure); the device may draw well in
excess of 1000 mA, ruining either itself, or the supply, or
both, with outward symptom of anything from non-operation to
smoke and meltdown.

In other words, don't do it.
