Question of the Week / QotW - 21.08.22 - How long does it take the food I eat to become part of me?

« on: 16/08/2021 16:17:24 »

We are hungry to hear what you think of a question sent in by Martin.

"I've started my annual lose weight push, but this year I have bought a set of scales and weigh myself daily. I have noticed that my weight fluctuates but that the trend is not straight, more like a staircase despite me eating and exercising similarly each day.

This got me wondering, how long does it the food I eat to become part of me?"

What do you think? Let's start a discussion.

Technology / How much electricity is wasted in transit to your home?

« on: 16/07/2021 09:21:16 »

John got in touch with us to ask:

"I read somewhere that over 50% of energy is wasted between power station and house/business due to heat losses. I recall this as being one reason why it's difficult to run underground high voltage cables. Is it really that much, and how much would it cost to 'fix the problem' and have local generation?

Secondly, how much did the Tesla battery in Australia cost, and would the construction of some of those be cheaper than all the energy wasted (or the cost of subsiding generators to to produce electricity) when there is a surplus (I'm thinking particularly of wind farms)? Does it work as expected?"

A leading question to really sink your teeth into. What do you think?
