"The passive-type bio battery system generates eco-friendly electricity by breaking down sugar using processes similar to those in living organisms. The speed/running-time of the toy depends on what drink you use"
The car is still a prototype for now, but once on the market, parents will be able to use the toy to encourage less waste and introduce a bit of life science. This invention looks more like a futuristic delivery truck. Oh, the more sugary the drink juicing the battery, the more power the car will receive, it should be noted that although for commercial reasons Tomy has chosen to use colas to promote the car (Coca-Cola, Sprite, 7-Up), the most efficient fuel tested was grape juice.
Well, maybe this can be helpful as substitute for gasoline, and to minimize drinking to much sugar content drinks.
