@DanielleFong Would be neat to see a demo of Lightsail round-trip efficiency. Video could be great promo and convince the many skeptics.

@DanielleFong I'm thinking a heavy weight suspended 10 m high under efficient gears so it falls slowly like GravityLight & lifted up again.1 reply 0 retweets 0 likes -

@DanielleFong How high the weight can be lifted up again using energy stored in air tank will clearly demonstrate round-trip efficiency in %1 reply 0 retweets 0 likes -

@DanielleFong A vertical rod near the weight could be graduated with length & percentages of efficiency compared to initial (full) height.1 reply 0 retweets 0 likes -

@DanielleFong You could cut out electricity, to limit conversion losses, and hook the compressor/expander straight into the gear assembly.1 reply 0 retweets 0 likes -

@DanielleFong Good gears are said to have a friction cost of only a few percentage points, so Lightsail's efficiency would shine through.1 reply 0 retweets 0 likes -

@DanielleFong Just an idea. I don't doubt you're very busy. Maybe for later; a convincing demo could be key to accessing mainstream market.3 replies 0 retweets 0 likes
@glafleche regardless you're right but this isn't the time for it. Demand for machines at our level of performance isn't the problem
