I think the best source of energy is not an alternative, but nuclear. Nuclear power generation produces no carbon emissions, is very feasible, produces as waste only low-level products that can easily and safely be dealt with, and is hugely efficient. Despite Fukushima, which was mismanaged and an generated an avoidable meltdown, it can be done safely and properly if done right. I think the biggest aversion to it for the masses is fear of the word "nuclear," which frightens people. This is by far the best way to make the power grid "green."

Have you ever seen people on YouTube make fidget spinners "forever" spin by using magnets?

There is a video that goes further and the spinning object powers a lightbulb.

I wonder if this can be used on a large scale.. or if it's all bs

the problem being hidden in the design, it takes a lot of infrastructure to produce high powered magnets, plus the maufacture of bearings, and all the other parts, but once the generator is built it may produce enough power to offset its cost, but its manufacture is still costing human time and resources not to mention the environmental cost to dig up the materials, so maybe not much of a game changer

Whats your favorite type of alternative energy source?

The product of a Japanese start-up called Challenergy, technology called the Magnus Vertical Axis Wind Turbine (VAWT) could make use of those damaging winds. Instead of the traditional propellers found on regular wind turbines, Magnus VAWT has a rotating cylinders that power a vertical-axis generator. It relies on the ‘Magnus effect’, a phenomenon that explains why air curves when passing by a spinning object. A Magnus VAWT turbine consequently has three vertical cylinders that rotate around a vertical axis to generate power. It’s already been tested in Nanjo City in Okinawa, Japan, where it withstood wind speeds of 225kph/140mph.

Although they’re don’t appear to be as efficient as regular wind turbines, if Magnus VAWT turbines can capture even some of the kinetic energy from a typhoon, that won’t matter.

There is not that much of it. All of the used fuel ever produced by the commercial nuclear industry since the late 1950s would cover a football field to a depth of less than 10 yards. That might seem like a lot, but coal plants generate that same amount of waste every hour.

The U.S. nuclear energy industry has safely transported used fuel without any harmful release of radioactivity, injuries or environmental damage. In fact, after 7,000 shipments total of used fuel by the worldwide nuclear industry since 1970, there have been no leaks of radioactive material or personal injuries.

Thankfully coal is coming closer to being a dead industry every year. The availability and low price of natural gas is the biggest reason.

The biggest barriers to alternative energy sources is oil money lobbying against it.
