Title: BTS Engine
The Blade-Thru-Slot (BTS) rotary engine features very low friction and reduced exhaust losses, providing:
- hybrid-class efficiency at low cost and complexity;
- 33% higher efficiency than gasoline engines;
- 19% higher efficiency than turbodiesel engines;
- onger lifetime and lower maintenance than conventional engines.
The BTS engine offers vast flexibility for biofuels and hydrogen. Widespread adoption would cut global carbon emissions from transport by 20-45%. The conceptual development is now complete. Practical development and market scale-up requires up to US$50 million along 10 years maximum. A first venture contribution is in principle available, and the rest is being sought.
