The cost of ownership is one-third and the fuel efficiency is eight times greater when compared to their gasoline-powered counterparts.

Benefits of 24/7 Battery Equalization

The equalizer captures energy from batteries with "above average voltage" and dumps that energy into the ones with "below average voltage". When the overachievers try to excel in voltage, their excess energy is used to bring the underachievers up to par.

Can Electricity Save Energy

With the increasing conversion efficiency of electricity in generation, the increasing share of renewable electricity, the high efficiency at the point of use and the potential for system level efficiencies, there is a lot of supporting evidence for a claim that electricity can save energy.

How Many Energy Slaves Do We Employ?

We use about 128,640 horsepower-hours, or the equivalent of 147 energy slaves working for each of us 24/7, all year long.

Is America ready for Wind Hydrogen?

While flow batteries and other devices can be used to compensate for wind's intermittent output, it's difficult to match the investor and political enthusiasm for hydrogen.

LED Buyer Beware

If you buy a set of 5 lights for 20 bucks do not expect it to last very long or hold up in extreme conditions. Research what you are going to buy, ask others and make an informed decision.
