• Question: Heyy xx Jack, can you answer me this question, How many lemons would it take to power a car, possible a particular car, maybe just a small car! Thank you for chatting to me, you have been a lot of help! You will get me through my science classes very easily now, because our topic is energy. It was great fun! xx Thank you x

      Hi … interesting question 🙂

      Using this page http://en.wikipedia.org/wiki/Lemon_battery I found out that a lemon battery gives:

      0.00027 watts

      For the car, we’re going to use the T.27 electric car – which is very very efficient.

      It uses 7000 watt hours of energy to drive about 60 miles in about 3 hours. So that’s an average of 7000/3 = 2333 watts

      So to the number of lemons you need is 2333/0.00027 = 8,641,975 lemons!!

      Loadsa lemons 🙂

      Can I get in on this one please?

      I was just walking home and some idiot overtook 3 cars on a blind bend going through the village. He was doing about 70 mph in a 30 mph zone.

      I reckon it only takes one lemon………………
