A new old way to make your bacon and eggs is here, from this week's New Scientist (UK):
Next-Gen Microwave Ovens are small enough to sling on your back

Get ready to nuke your packed lunch: a new era in microwave cookery is around the corner. As well as portable ovens you can stick in a backpack, electronics will enable appliances that detect when their contents are thawed or risk boiling over, and smart ovens which will cook multiple items at different rates simultaneously.
Conventional microwave ovens use a cavity magnetron, a vacuum tube developed for radar during the second world war. Magnetrons are heavy and not efficient at generating microwaves. They may also create hotspots, a problem not totally solved by rotating the oven’s contents on a turntable.
Laterally diffused metal oxide semiconductor (LDMOS) microwave sources promise to change that. Similar to those in cellphone towers and microwave communication systems, they are now being worked on by firms such as NXP, based in Eindhoven, the Netherlands. “The underlying technology has been here a long time; we’re making changes to make it more specific and suited for consumer cooking appliances,” says NXP’s Paul Hart.
The compact size and high efficiency of the source makes portable microwave cookers possible, such as the 1.5-kilogram Adventurer from Wayv, a company based in Hertford, UK. Pictured above, the Adventurer looks like a large thermos flask, and its NXP source can heat up to 500 millilitres of food or drink in cycles of up to 5 minutes. The rechargeable lithium-ion battery is good for six cycles on one charge.
The Adventurer raised £150,000 in less than 19 hours on the crowdfunding site CrowdCube in 2014. It will be launched first in the US early next year and will cost about $199. Wayv envisages it being used by campers and hikers, as well as the military and first responders. Unlike with camp stoves, there is no smoke or danger of carbon monoxide poisoning.
Chris Brock, director of the London Food Centre at London South Bank University, says that the Adventurer’s usefulness for camping or hiking is limited due to the number of cycles that the battery allows — food and drink for one person would require two or three cycles per meal. But he suggests the Adventurer could also be used in experiments that require heating in the field.
