Unlike a lot of those other hot-shot bots, the "Robot Bank" isn't here to show off--it just goes about its business, encouraging you to save for the future and diligently toting up every penny you drop in. Don't try to cheat, either: It recognizes withdrawals and will make disapproving noises if you try to sneak a few bucks.
How can you make ice at 15 degrees higher than freezing? You're looking at it.
This tub pictured here, made by Transphase Phoenix, is designed to hold water permeated with various salts so that it will freeze at 47 degrees rather than the standard 32. That means ice can be made at night without as much electricity when power is cheaper. The idea is to reduce peak demand in the afternoon, when electricity is most expensive, and obviate the need for "peaker" plants.
The ice melts throughout the day, providing air conditioning in as many tubs as … Read more
The future of light is plastic, says Cyberlux.
The company, which specializes in light emitting diodes (LEDs, will come out with prototypes of a new type of white light LEDs in about four months that will cost substantially less to manufacture than conventional LEDs and provide more light at the same time.
In conventional white light LEDs, a semiconductor emits blue light. The blue light passes through the phosphor and becomes white light. The phosphor is thin film on a substrate; the substrate has to be placed in intricate proximity to the semiconductor. Positioning the phosphor is one of the … Read more

I'm a little skeptical of the appliance's capability to make food that actually tastes good (Doesn't it kind of look like a kid's toy? That could be a bad sign.) But if you have a cramped kitchen, it could be a potential space-saving solution.
I'd get it if there were an orange juicer built in. Or if that egg fryer on top could … Read more
