As the population continues to increase day after day, so does the demand for oil and other natural resources. Eventually we will get to a point where we will need to find different ways of efficiently producing energy at a low cost. Twenty to thirty years ago it was hard to imagine what sources of energy (other than obvious possibilities like solar panels and windmills) that could efficiently supply the world. The advancement of technology today is opening new doors in the energy field that are likely to change the way we think about energy. With so many different sources of energy that are prevalent around the world, the challenge is found in harvesting and securing the energy at its source, and doing so in an efficient manner.
I decided to do some research about possible future sources of energy, and my search turned up some interesting results. One of the most basic yet potentially worthwhile investments was found on an alternative energy website. This particular article talks about the use of flying wind farms. These flying wind farms are essentially "airborne turbines spinning at high altitudes sending power down via nano-tube cable tethers to generate power." Basically there would be two turbine's attached via the nano-tube cables that would fly high in the sky like kites. The strong wind from the high altitude would allow the turbines to capture and transmit the energy down the cables. The idea was being explored by NASA who said that the turbines would have to function at altitudes above thirty thousand feet. Some advantages of having turbines so high in the sky is that the wind is between eight and twenty seven times stronger than the wind at ground level. Clearly there are many difficulties that would have to be addressed including maintenance, air space issues, safety, etc, but flying wind farms are a potential source of future energy.
Another form of energy that could become very useful and resourceful in the near future is the transformation of human waste into energy. An article by Janet Zimmerman describes a process being developed by an engineering firm named UC Riverside. The new process "uses heat and pressure to turn human waste into clean energy," saving millions of dollars and reducing pollution in the process. This idea has the potential to change the energy industry since there will never be a shortage of human waste. The first step of the process "pumps a combination of municipal sewage, sawdust and water into a pressurized reactor that is heated to almost 1,400 degrees." (Zimmerman).
