next-gen microwave ovens are small enough to sling on your back - lithium ion rechargeable battery

David Hamblin is preparing to blow up your packed lunch with nuclear weapons: a new era of microwave cooking is coming.
In addition to the portable oven you can put in your backpack, the electronics also allow the appliance to detect the risk of when their contents will thaw or boil, and the smart oven, you can cook a variety of foods at different prices at the same time.
The traditional microwave oven uses a cavity-controlled magnetic tube, a vacuum tube developed for radar during World War II.
The magnet is very heavy and cannot produce microwave effectively.
They may also make hot spots, and the problem is not completely solved by rotating the contents of the oven on the turntable.

The microwave source is expected to change this situation.
Similar to mobile towers and microwave communication systems, they are now being developed by companies such as NXP, based in Eindhoven, the Netherlands.
"Basic technology has been here for a long time;
"We are making changes to make it more specific and suitable for consumers to cook appliances," said Paul Hart of NXP . ".
The compact size and high efficiency of this power supply make it possible for a portable microwave cooker, for example, 1. 5-
Kilograms of adventurers from Wayv, the UK's Hartford company.
In the picture above, the adventurer looks like a huge thermos, and its NXP source can heat up to 500 of food or drink in a 5-minute cycle.
Rechargeable lithium
The ion battery is good to charge six cycles at a time.
In 2014, the adventurer raised £ 150,000 in less than 19 hours on crowdfunding site CrowdCube.
Early next year, it will be the first to launch in the United States, costing about $199.
Wayv envisions it for campers and hikers as well as for the military and first responders.
Unlike the camp stove, there is no danger of smoke or carbon monoxide poisoning.
Chris Brok, director of London Food Center at Southbank University in London, said that because of the number of cycles allowed by the battery, adventurers have limited use for camping or hiking
One person's food and drink takes two or three cycles per meal.
But he suggests that adventurers can also be used in experiments that need to be heated in the wild.
NXP is also developing its own precision oven.

Multiple microwave sources and convection heating are included.
With multiple sources, Sage can sense individual items and guide the microwave to cook them in different ways.
The technology in Sage can feel the change in the resistance of the contents, and the resistance changes as ice becomes water, or water becomes steam.
This means that it can unfreeze a meal without cooking, or stop while the soup is boiling.
For example, the company claims that, despite the different heating requirements of Sage, it can perfectly cook chicken, potatoes and peas on the same plate.
It also says that Sage can also cook or thaw complex items, such as sponge cakes filled with cream, to heat each ingredient evenly.
It will also support new takeout or fast food optimized for "smart cooking.
"This is just the tip of the iceberg," Hart said . "
