Notas do Editor
- Who does not have one of these?I’ve heard that there are now more cell phones on the planet than there are people!Do you know what these run on?
- You probably think they run on batteries.Actually they really run on chargers and wall outlets.
- Have you ever experienced “range anxiety”?Lose the “Leash”
- The amount energy contained in the sugar content of a can of soda is equivalent to about 60-80 AA alkaline batteries
- It runs on the same thing this little fellow runs on – sugar water!Safe, friendly, inert.
- The amount energy contained in the sugar content of a can of soda is equivalent to about 60-80 AA alkaline batteries
- The amount energy contained in the sugar content of a can of soda is equivalent to about 60-80 AA alkaline batteries
- So think about being disconnected from the grid for an extended amount of time.Say 14 days off the grid, would require some 63 AAA batteries (almost a kg) or just a few grams of sugar water.
- The CFDRC BioBattery charger is an off grid solution.What does it run on?
- We have already covered the portable chargingSimilarly for disater relief everyone remembers April 27, 2011 and last year’s tornados and trying to get powerToys/greeting cards – trying to overcome dangers to kids. ABC News National story on Aug 30, 2012 Overall, the two studies suggest that the 6.7-fold increase in the percentage of button battery ingestions between 1985 and 2009 (>50,000 cases). Overall, there have been 14 deaths involving button batteries getting lodged in the airway or esophagus (7 of those in last 2yrs).Insect Cyborg we showed is a really a segway into implantable med devices. Sugar in body, infinite supply, last forever
