CleanTech 123

Is Mattel's recalling of toys with lead paint a quality control issue or CleanTech issue? It depends on how you define what's CleanTech. Many people are familiar with Energy and Global Warming related CleanTech topics, but pay less attention to other areas needing equal "clean" treatment, such as safety toys, food etc.

So I try to incorporate as many things as possible into CleanTech by coming up with following expanded definition:

lAny products, services, and processes that harness renewable materials and energy sources, improves natural resources utilization and utility rate, dramatically reduce the use of natural resources , preserve/restore environment ecosystem, and cut or eliminate emissions and wastes.

Thus, the process of eliminating lead in paint or paint product without lead or any other harmful chemicals should be considered CleanTech.

CleanTech can be categorized into following 7 sub-categories:

1. Renewable Energy
lWind Power
lWater/Hydro Power
lHydroelectric
lMicro Hydro
lWave Power
lTidal Power
lTidal Stream Power
lOcean Thermal energy conversion
lDeep lake water cooling
lBlue energy
l
Solar Energy
lPV Solar Cells
lConcentrated Solar Power
lSolar updraft tower
lpassive solar design
lsolar ovens
lsolar-thermal panels
lsolar chimneys
lsolar power satellites
lThin film
lBiofuel 生物燃料
lLiquid biofuel (ethanol, butanol, biodiesel, and straight vegetable oil)
lSolid biomass (bargess, wheat chaff, corn cobs, switchgrass, miscanthus, willow, field pelletize)
lBio Gas
lGeothermal Energy (Dry Stream, Flash, and Binary) 热能

2. Energy Efficiency
lClean Coal

Clean Fossil Fuel
lEnergy Efficiency
lGreen Building Materials

3. Transportation
lElectric Motors/propulsion
lAdvanced Battery Storage (Battery, fuel cells, ultra-capacitors)
lAlternative-fueled Vehicles
lHybrid-electric vehicles
lHydrogen Refueling stations
lFuel Cells
lCoal fuel Cells

4. Smart/Green Power
lDistributed Power Generation & The Virtual Utility
lGreen City
  • lWaste streams recycled into new sources of energy, water, and useful materials
  • lUtility-scale solar thermal plants
  • lSelf driving vehicle

5. Pollution Control
lCarbon emission reduction/offset
lGreen Chemistry
