Frozen food in bad shape, by Albayzín, with 190 positive votes
This idea is about avoiding that frozen food bought at the supermarket has been defrosted and again frozen because a faulty cold chain. If the packaging of the frozen food has a sticker with a white box on it, and this sticker turned red if the product has been defrosted (without becoming again white when frozen again), this would alert buyers and help them refuse to buy that food.
The idea most voted positively in ENVIRONMENT & SUSTAINIBILITY is:

The lift at your home…MAY SUPPLY YOU WITH ENERGY!!!, by edugilweb, with 42 positive votes
This idea is suggesting the following: “What we know as regenerative braking (this is, to benefit from the energy driven away while the motors are braking), is already applied in railways. Why not using this technology with the lifts of the buildings, the parking, the subway, etc?
In the railway sector, the regenerative braking means –broadly speaking- that the one train that has to use its brakes (because entering a station, or because it is passing a working area or with is slowing its speed for any reason, gives its energy away through the overhead line to another train close to it that is about to start. This could be easily done at the subway, where trains are continuously stopping and accelerating.
Well, this regenerative energy could be used in a similar way with lifts.
