overview
Overview
  • Irrigation critically lacking in third world countries.
  • Current pumps do not meet economic and ergonomic requirements of farmers.
  • Bicycles are prevalent and relatively ergonomic mode of transportation.
  • Bicycle powered pump answers irrigation need.
potential markets
Potential Markets
  • India
    • People: 58% of population in agricultural labor force
    • Equipment: ~100M bicycles
    • Demand: need for irrigation water predicted to rise dramatically
    • Potential Concern: not socially acceptable for women to ride bicycles
  • China
    • People: 50% of population in agricultural labor force
    • Equipment: ~750M bicycles
    • Demand: only 40% of cultivated land is irrigated, yet produces 67% of crops (www.worldbank.org)
    • Many government sponsored irrigation projects fail due to poor efficiencies and lack of system maintenance
  • Summary- $1 billion market for $50 pump (2.5% market penetration)
moneymaker pump benchmark
MoneyMaker Pump Benchmark
  • max pumping rate = 1.5L/sec
  • total pumping head = 13m
  • max useable well depth = 6m
  • max distance pumping across flat land = 200m
  • max amount of land irrigated = 2.4acres
  • pump weight = 20kg
  • manufacture cost = $200
  • consumer cost = $50
critical issues benchmarking
Critical Issues Benchmarking
  • Cost
    • Goal: To be most cost effective human powered pump in third world market
    • Bellows design makes piston a disposable commodity item
  • Ergonomics
    • Goal – To provide a more comfortable pumping system than MoneyMaker pump
    • Proven that cycling lower impact than running
  • Efficiency
    • Goal – To design a pump of equal or better efficiency than MoneyMaker pump
issues addressed by mockup
Issues Addressed by Mockup
  • Feasibility of low cost goal
    • pump built for less than $25
    • Critical bellows component costs on order of pennies
    • Still need to reduce cost of other components (valve etc.)
  • Pump Design
    • Various designs considered, bellows chosen on cost basis
    • Bellows pump found to work best when two are run in parallel
  • Efficiency
    • Design for taking power off rear wheel – still needs testing
    • Pump – still need to address valve and sealant issues
mockup design
Mockup Design
  • standard bicycle fits into universal stand
  • power taken off rear wheel with roller
  • roller transmits power via chain to crank shaft
  • crank shaft powers positive displacement bellows pump
pump testing

Difficulty achieving pump head, priming pump may improve performance

Better flow rate, high inertial forces due to discontinuous pumping action

test results manual
Test Results (Manual)
  • Single bellows hand pumping rate = .75L/sec
  • Inertia matters!
  • Double out of phase bellows reduced force by ~6x
  • Priming necessary
  • Cheap pump feasible
future work lessons learned
Future Work/Lessons Learned
  • Install double pump technology/dual reservior to reduce inertial forces
  • Reduce compliance in power transmission
  • Implement drive reduction
  • Extract quantitative data from mockup - measure efficiency
  • Pumps are fun!
