I like your LED idea alot ! I interpret backtoback as meaning the LEDs are in series with opposing polarities . Just to clarify , SdNETwQa means for the diodes to be in parallel but with opposing polarities . Also unless energy is some how stored , the flashlight will only work while shaking it . It won ' t be very use full since you cant aim the light while shaking . <| sep |> right and I say no to your major regulations , anor sanctions against what you define to be recalcitrant countries . Who are you to decide what a healthy world is , and how shit gets done . Thinking you know best , and should be able to impose your will onto others in the form of I know best laws is the real recalcitrant attitude here . Ive read all the research , I know the studies , I understand the science . You ' re alarmist ideology is a resounding echo chamber in the scientific community right now . Any dissidence gets stamped out by the majority with vehement claims of social irresponsibility and ad hominem . Its embarrassing science , really . Queue your montage rant about morality and social responsibility full of passive aggressive andor direct insults of my intelligence .
