Every source of energy has risks associated with it coal for example you know has in the past released silver dioxide and acid rain things like that coal tailings can lead to environmental issues burning of fossil fuels clearly has impacts on the environment there's no free lunch in the energy picture. There are new reactor designs that are more efficient at burning up the fuel and producing less waste but ultimately we think fusion energy could really replace vision energy. It's much more inherently safe doesn't have the chance of uncontrolled reactions the fuel is ubiquitous you can find it in sea water and in the ground lithium and dutarium are readily available  and it's really could be a game changerWe're thinking about waste
