Only if you find some valuable use for the waste heat generated by the compressor, e.g. for domestic hot water, as Robin suggested some time ago. The energy balance for 300 L at 300 bars is as follows: At compression time: In: 12 kWh electric Out: 3 kWh compressed air intrinsic energy (P*V) + 9 kWh heat to ambient At expansion time: In: 3 kWh compressed air intrinsic energy + 9 kWh heat from ambient Out: 12 kWh mechanical Michel ----- Original Message ----- From: "Jones Beene" <[EMAIL PROTECTED]> To: "vortex" <vortex-l@eskimo.com> Sent: Thursday, July 31, 2008 9:30 PM Subject: [Vo]:Doubly disruptive? > New article on EEStor ... still not out yet, but the > hype continues. > > http://earth2tech.com/2008/07/30/eestor-the-story-so-far/ > > It does bring up one point, however. > > Being ever the optimist, what if the Negre air-motor > and the EEStor get to market at the same time (SOON > hopefully)- is there any potential for synergy there > between the two "disrupters" ? > > At first it seems 'not likely' as they are so > different in the way they operate - but look a little > deeper. > > Any drive-train will probably benefit from going "all > electric", particularly if the "motor-in-wheel" > technology is available.
