Power Tools

Power Tools

Nothing particularly wrong with power tools per se. However, they do suffer during poor weather, same as safety spectacles mentioned above. The problem is that in cold weather the flex, well doesn’t flex. The flex has a PVC outer insulating sheath that gets very stiff in, not excessively, cold temperatures. Around 0oC. The flex on irons is nice and flexible. That’s because it is sheathed in flexible rubber, and then has a heat resistant braded fabric outer sheath. Why can’t we have something similar for power tools?
There was a famous electrical engineer called Nikola Tesla who apparently was working on a way to transmit electrical energy wirelessly. This was proposed to work across considerable distances. So I guess it would be ideal for power tools as you would then not need to worry about chopping through the wire on your hedge trimmer (I have the T-shirt for that one too 😳 ). You can, however, get electrical transfer of energy over short distances. This has been used recently to charge mobile phones without needing to plug them in. This works by electrical induction. Essentially if you put a coil of wire, which is carrying an electrical current (say it’s connected to both ends of a battery) next to a coil of wire (which is connected to a little light bulb say) then the current in the first coil “induces” a current (a movement of electrons) to flow in the second wire and the bulb lights up. Obviously this is not what I mean to use for power tools.
There has been a lot of nonsense has been written about Nikola Tesla, over the years, so it is often difficult to sort the wheat from the chaff.
