They are allowed to use a rice cooker, so the rice is not an issue.
In regards to how easy it is to make omelet rice on a hotplate, I don't know about in other countries, but in the US these days, you're lucky if you can get a hotplate that will boil a pot of water. Electric kettles are great, but it's hard to actually cook on a tiny element "burner" that turns itself off all the time in the name of safety. Good luck finding the right temperature as well. If anything, this is probably what Minko is concerned about. She's used to using professional level equipment, and furthermore, natural gas. if you want to cook outside of a kitchen, that's what propane stoves are for...at least in my country (either portable burners or a gas grill). That's not the worst thing though. Countertop Fryers in the US will barely get to 350°F (175C), much less the 400°F (205C) that you need to cook tempura and the like.
