| In calm weather, the gases would explosively recombine in combustion engines turning dynamos. |
| When the cars slow down, their energy is captured in dynamos that recharge the battery, rather than being wasted simply heating brake pads. |
| Faraday fooled around with wires and magnets and batteries, making the first electric motors and dynamos. |
| By 1901, Thaddeus Cadhill had already manufactured the Telharmonium, an electric organ, powered by dynamos and designed to send sound down telephone lines. |
| This he established in 1836, using it to give details of his electromagnets and their application in motors and dynamos. |
| Of its 50 dynamos, 41 are in consumer businesses, where they can exploit a more intimate understanding of their compatriots' tastes. |
