UELVEs MBC
Acronym decoding:
- UELVEs: Ultra-Efficient Libre Vehicles for Everyone.
- MBC: the Embassy, or the "MythBusters Car" (get it?), in honour of their discovery that a golf-ball texture on a car bodypanels significantly improves fuel economy. https://www.youtube.com/watch?v=VUiGhyHC-1A
Specifications
- 4 wheels using mountain bike 19in rims and 2.75/19 motorcycle tires
- 100kg weight
- 2 occupants
- Twin 3-5kW Axial Flux BLDC chain-driven motors (no gearbox needed)
- 1.1 x 1.5 x 3.4 metre dimensions with an "airbox" down the centre
- Only a 1.1 m^2 front surface area (due to the "air tunnel")
- 0-60mph in under four seconds (Sur-Ron "3" kW Motors can be pushed to 13kW for short durations, and there's two of them)
- over 200mpg at 55mph due to low weight, low rolling resistance, reduced surface area and low drag coefficient.
Design Concept
- Use downhill mountain-bike parts that have been proven to be light, strong and effective up to a 50kg weight with an 80kg load, thanks to the Sur-Ron Electric Bike.
- Use twin Sur-Ron direct-drive 3-5kW Axial Flux electric motors
- Use twin ASI BAC4000 BLDC Controllers (or VESC Vedder BLDC Controllers http://vedder.se/2015/01/vesc-open-source-esc/)
- Outer skin using the GABoats technique (Geodesic Aerolite Boats) - http://gaboats.com
- Inner frame using 3D-printed fibre-reinforced "nodes" connecting continuous-fibre-reinforced pipes on a Fibre_Reinforced_Pipe_3D_Printer or getting carbon-fibre, hemp-reinforced tubes (or even Bamboo), based on the Divergent 3D "Blade" car manufacturing concept https://www.youtube.com/watch?v=vPv7PwS50OE
- Epoxy-soaked cloth "wrapping" carried out on joints, if necessary, using the Calfee Design Bamboo bike technique. https://calfeedesign.com/what-is-in-calfee-diy-kits/
- Swappable Modular batteries using the Open_Source_Battery_Pack
