It might be an antique but....It will still be working long after I'm gone.

After watching the first in the BBC series Electric Dreams as the programme follows a family as they are regressed back to 1970s technology (having to suffer 1970s style economic recession with the oil crisis etc, Oh the nostalgia ) what robust and simple technology will still be working in the next 50 years.

What piece of survival kit/household technology if you bought today will still be useful in 50 years time. I'll start the ball rolling with the Simplex copper kettle.

Can you still buy a Mangle like my gran used to use with her twin tub waching machine back in the 1970s.
