Well done for that, it'll be so worth it once we "tayk bk r cuntrey" and show the rest of the world just how quiet 'Rule Britannia' plays these days.

And Project Fear raises it's head yet again.

Yes, we call them drones.

Do you have any idea about the energy density of battery versus for instance kerosene?

For a plane to carry the same amount of energy (at sea level, not even talking about loss off energy in batteries due to temperature drops at high altitudes) at this time a plane should carry 23-46 times the amount of weight of batteries to bring the same amount of energy as kerosene.

https://en.wikipedia.org/wiki/Energy_density

That means before planes will be using batteries they have to increase the amount of energy stored in a battery 23-46 times without any increase in weight and increase the reliability at the same time, because batteries have the tendency to become unstable (self igniting) under certain conditions.

More than a hyperdrive needed to achieve that.

You should really research before showing your ignorance on this subject.

Already, flight schools are using electric powered planes for take off and landing training. A 2 seater has about a 1 hour endurance level and that is with bog standard Lithium ion batteries. The next generation of aluminium air batteries already have a 30% to 40% greater capacity weight for weight than Li-ion. Already 1st stage graphene based batteries are demonstrating a 500% increase in capacity weight for weight over Li-ion.

Change your aspect on travel and look at the safest plane in the sky, a Gyro copter. Three seater Gyros are capable of up to 500 miles on a single charge with an electric motor. They can take off and land on a sixpence (or a dime for our Amrican cousins) and again, this is with bog standard Li-ion batteries.

Start boning up on technology beacause Phnom Poon is correct, you have a Flintstone mentality. And of course, don't rely on Wikipedia for information. Also, Graphene based batteries are non flammable.

I can't see the problem, though I have not studied it extensively; in the old days the commonwealth was a very robust trading bloc.
brexit is going to happen and it will provide many new opportunities.
europe is not in very good shape financially.
the yanks will soon stop providing security.

forgive my naive comments, but i cannot see how the short term pain will not be a good trade for longer term independence.

get off your asses and produce more.
you have all the resources.
