They contract along their nematic director when heated or illuminated. The shape changes are large and occur in a relatively narrow temperature interval, or at low illumination, around the nematic-isotropic transition. We present a conceptual design of a mechanical, turbine-based engine using photo-active liquid crystal elastomers to extract mechanical work from light. Its efficiency is estimated to be 40%.","authors_text":"Mark Warner, Milos Knezevic","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2014-06-19T21:19:57Z","title":"Optomechanical conversion by mechanical turbines"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.5217","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:898d85cc301906f4229674e621e631e618246d4c4af9e0cce94452cce6c56720","target":"record","created_at":"2026-05-18T02:38:52Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"97f0c8c0bbcfc563917da2f9f3e9cc9a100f4d88581100339f13b875903367dd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2014-06-19T21:19:57Z","title_canon_sha256":"147d2e083e05834425fe5fd7591c14de0251e7ff34f0b58add815a1afd3e7e53"},"schema_version":"1.0","source":{"id":"1406.5217","kind":"arxiv","version":2}},"canonical_sha256":"7eb191d8a9a3a357f857f13500a91ab615c90a7e1081a3edc3c0fe4d793c02f2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7eb191d8a9a3a357f857f13500a91ab615c90a7e1081a3edc3c0fe4d793c02f2","first_computed_at":"2026-05-18T02:38:52.907087Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:38:52.907087Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fiqJyxmYRNngkUJd6ylMGEVRb2jTd3DBwczNPp/+aHu7oq/rPeXA+zgKwTlJ/rOnBGCqUjzS3KTH/6OU4TaNBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:38:52.907435Z","signed_message":"canonical_sha256_bytes"},"source_id":"1406.5217","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:898d85cc301906f4229674e621e631e618246d4c4af9e0cce94452cce6c56720","sha256:c1f890ef38b3ce24aea2bfc5a58925040ecc2bc9a83fa642cc414938f46199f1"],"state_sha256":"c71bca9c862c9f94fbe295a591c469143cc2c66675493bd2bf08618a2f27f26a"}
