I think it is pretty misleading if they just gave the peak device power density. As in the car analogy given in TFA, if you were to burn all 270 Calories of a single Snickers bar in a thousandth of a second, your device would have a peak power of about 1 gigawatt, comparable to a large nuclear power plant. Yet if your publication said you had made a 1 GW device instead of saying that your device could power a single average home for 17 minutes, you reasonably be accused of misleading. Surely a subtext of the research was that energy sources are important to humanity.
(Sidenote: Huh, a snickers bar can power a home for longer that I expected.)
- aetherspawn 7y agoI would be interested to see a food chart that described how long various things can power a home in minutes. Can a salad power a home longer than a snickers bar? Or what about a potato.
- saagarjha 7y agoWhile I don’t have numbers, your questions are easy to answer: foods with more calories in them can power your home longer. A typical 700 calorie meal can, if used 100% efficiently, can power a 10 W LED lamp for about three days.
- wiredfool 7y agoYeah, Dietary Calories are actually Kilocalories in engineering terms, so it's a pretty energy dense material.
