  • VaporRemed helped in recovery of pets

    We recently converted our oil boiler to gas and the heating crew could not remove the half-full, 250-gallon oil tank until one week later. Hence, we had an open fuel oil tank (the pipes were removed) and strong oil fumes inside our home. As a result, our dog and cat became ill within a few hours. Upon receiving and spraying the VaporRemed, the fumes quickly disappeared and the animals recovered. ...

  • Energy taxes and subsidies: their implications for CO2 emissions and abatement costs

    Energy markets are often distorted, with the result that price does not equal the marginal social cost of production. Subsidies encourage consumption of energy and impose welfare losses independent of those arising from global warming. Fossil fuels, especially oil, are already taxed in many countries. The superimposition of a carbon tax on existing taxes could greatly increase the welfare loss ...

  • Forest fuels reductions and biomass to Energy: Parallel opportunities for public benefit

    Larry Mason has investigated the links between forest health problems and biomass to energy. “There are some real disconnects,” he said. Washington’s Inland West is “at a high, unprecedented risk of a catastrophic crown fire,”unless fuel loads are reduced. The rhetorical problem with reducing these fuel loads is that the cost of removing small diameter fuels may exceed their market value. “But ...

  • Observing the effects of digestion and chemical dosing on the calorific value of sewage sludge

    New legislation being introduced in Europe for the removal of the macronutrients nitrogen and phosphorous is causing the fundamental composition of sludge to change.
