What is the workplace of a Video Game Designer like? Game designers typically work for gaming companies such as Blizzard, Electronic Arts, Microsoft, Nintendo, Sony, etc. They typically work in an office or studio-like setting amongst other designers and programmers.
Hydrogen, bound mostly to carbon and nitrogen, is part of almost every molecule in your body: DNA, proteins, sugars, fats. In fact, the hydrogen bond-which forms between atoms that share a hydrogen, is one of the most important interactions that makes biological molecules behave as they do.
Hydrogen can be used as a fuel, it's a proven technology. The problem with doing this on a large scale is that there's not enough naturally occurring hydrogen, so the hydrogen would have to be generated. One way to generate hydrogen is by electrolysis of water. Another way is by burning natural gas. Both of these methods are energy intensive.
