Probably no harm apart possibly from thermal shock to delicate glassware, but some of the 'clever' ones might treat it as an error condition and stop.

Calculating rpm from pulley sizes is not likely to be accurate because the effective diameter is rather indeterminate especially for small pulleys. If you can't get hold of a 'scope to look at the waveform you might try listening to the output via a suitable step down transformer and loudspeaker (or...

Agreed about the black boxes but new shiny (or grubby in my case) cars have a much lower failure rate despite their increased complexity and electric ones should be even better. In the last 15 years or so - excluding one accident and yjr odd puncture - I've only had one incident needing assistance (...

Its not the 'newness and shinyness'. Its the reliability and backup. Many of the offerings on the market (no disrespect to other posters!) are here today and gone tomorrow when something goes wrong. This should not be so with an vehicle from (say) Toyota/Mitsubishi/Subaru. Forty five years ago I car...

Only accidentally, and the sustained high voltage with no load blew up the capacitors! But in principle it can be done.

I, like may others I'm sure, am waiting for an electric car which meets my needs for local use. The 'city' type are so speed limited as to be useless and possibly dangerous in my extra-urban environment. It must be able to do 50 and preferably 60mph. A range of 40 miles is probably enough but it has...

Same problem here. The signature box is missing. It is normally after 'interests' in the profile information. Someone seems to have stolen it. ?A phpBB update or somthing?

Our 60A supply has survived 6 years so far and doesn't get noticeably warm under heavy loading. We have overhead distribution and the only way they could/would increase our supply was to add an additional 60A via a separate underground cable - at a high cost and with me providing the duct under the ...

A survey should always include some atypical entries - so here's mine: 1 Good Energy. 2 Standard 100% renewable tariff. 3 About 350W - fridge, freezer, heating controller & time switches, Freeview box, modem. 4 All electric heating (reason for 2) so mid-winter peak load can reach 10kW or more. M...
