Techno Mum’s Tech Trivia: Energy

Welcome to Tech Trivia – the gameshow that tests the technical talents of our tremendous contestants!


Techno Mum is taking part in an exciting new quiz show which is testing her knowledge about how some of the coolest new tech discoveries came about – in this episode the topic is ENERGY. 

Why is energy important in technology?

energy-2Energy fuels our world.  It powers factories, runs cars, heats our home and keeps our gadgets working.  Without it?  Well, we’d pretty much grind to a halt!  Can you imagine a life without your tablet?  What a terrible thought!

Energy can be expensive – you’ll know that if you’ve have to buy batteries for your toys or seen your parents pay for the fuel in the car.  It can also create pollution which can harm the planet.

That’s why engineers are looking at ways to get new products to use the least possible energy whilst still delivering the experience that people want. 

That might be by designing new chips that can run using less energy, or technology that that switches off a car engine when its waiting at traffic lights, or light bulbs with sensors that only switch on when they detect a someone moving nearby.

Electronic skin!

 Sounds a bit gruesome but it’s an invention that’s being developed right now – it’s not really skin but solar power cells which are so thin and flexible that they can be put into clothing. Just imagine – your clothing could power your mobile phone!

A tech job that’s all about getting the most out of energy:

Car Engineers – they design engines that use less fuel or run on different types of fuel – like electricity instead of petrol or diesel.

They also come up with ways for vehicles to cause less pollution ….all without going any slower if at all possible!
