Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

If one has a device that is so badly designed that it cuts out at 1.4V, and that device has a relatively low drain, then this device can provide about a 5X - 6X gain in battery life for that device.  I do not know of any such devices.  The vast majority of poorly designed devices drop out around 1.2V where roughly 40% of the battery life remains, not 88% as at 1.4V.  In those devices about a 2X gain can be had.  Most devices these days will run a battery down to 1.1V where only about 15-20% life remains against a 0.8V drop out.  Assuming that the circuitry is 100% efficient ( which it isn't ) you would get 1.0/0.85 - 1.0/0.8 or 17% - 25% more life out of the battery.  If their converters are 90% efficient, then you get 0.9/0.85 - 0.9/0.8 or 5% to 11% more life.
