Abstract Hot tubs are very popular across America due to their relaxation as well as health benefits. Hot tubs have been attributed health benefits ranging from relief of muscle and joint pain‚ to help in treatment of HIV and other viral infections. Because of this‚ many people own hot tubs and many more go to health spas where they can use them. On the other hand‚ hot tubs are not that easy to maintain. A consistent disinfectant level must be maintained in order to inhibit the growth of

Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality
