We get vast amounts electromagnetic radiation from a nearby nuclear fusion device about 150 million Km away, the frequency is much higher than 45MHz but it is easy to capture when the Earths rotation does not get in the way.
The amount that your "radio towers " could pump out would be utterly trivial in comparison.
I think estimate of a 10% payback on average from the cost of a ticket was pessimistic I have always understood that for every pound you spent on tickets on average you got back 25 pence but you would have to buy tickets for a long time to achieve this.
From a financial point of view the best bet is not to buy tickets !
I should not presume to tell the ESA team how to operate their comet lander but I am surprised that if it is receiving maybe 20% of the anticipated sunlight needed to maintain its batteries charged could not all scientific programs could be shut down leaving enough power to maintain communications until the comet gets closer to the sun.
I have noticed a change in the south east UK in recent years we used to have a cold November a mild December and any thing up to three cold months in the new year but recently the cold weather has not started until December but warming up by Xmas but little real cold weather in the new year.
The UK is a strange place for weather the late December and late June temperatures are often both about 12°C.
I have a rather antique printer 1995 (LaserJet 4 M Plus) vintage that normally serves me well but today I tried to print out a 29 page PDF document using Acrobat 10.0 and ended up having to print one page at a time with missed portions and many strange error messages.
So I hunted around and found a free and simple PDF reader Sumatra PDF that worked like a dream.
I only have windows 8.1 and Windows 10 systems maybe it would have been OK with an older system.
PS I Tried with Puppy Linux but could not get the usb printer to connect
I hate speculating about lottery numbers, it would be heart breaking if one wrote down a series of numbers for some reason or other, did not buy a ticket and then found you had written down the winning sequence although normally you would be better off by the price of a ticket.

It is frequently proposed that large optical telescopes should be built on the moon but now that terrestrial telescopes of 30 meters or larger with adaptive optics are being built which will far out perform Hubble there seems to be little incentive.
There may be a case for radio telescopes on the far side of the moon to receive low frequencies free of interference but the cost would be very high and would yield little science.
Gravity wave receivers should work well in space if technical problems can be overcome.
I would not dream of buying a lotto ticket or even filling in a number on an un entered one in case by some mischance it proved to be a winner.
Out of curiosity I listened to the spiel of a conman selling books for $99 telling you how to win and got curious as to how the numbers are computed.

They are certainly not a hoax they really work but the only snag is the capital cost rather like that other free lunch solar panels.

When you say that the gravitational field can not be shielded you must be implying that the graviton has zero mass as even the very low mass Neutrino can be shielded against in theory.
I think you will find the 5kW Russian device was actually a fission reactor not a thermo electric generator, as Alancalverd points out the only PU isotope that provides a useful amount of heat is U238 which is extremely expensive and difficult to produce to the extent that designers of satellite PSU,s are planning to use the more efficient Stirling engines rather than Peltier junctions

Such talk is going to depress the value of the shares in the company I intend to set up to sell heat pump-sterling engine systems.

I have always believed that the energy in radiation and that locked up in matter is counterbalanced by the negative gravitational energy so that the net sum is zero.

If it is thermal insulation that is required there are many light weight foam like materials that will provide a comparable degree of insulation to that provided by a vacuum.

A few submarines have been built to carry aircraft but generally it is not a very happy combination.
Many submarines can launch cruise missiles while submerged I guess they are aircraft of a sort.
