Mr Hawkes. There is research into these weapons. What, in my childhood days of of sci fi such as Fireball XL5, Thunderbird, etc were called "Ray Guns". The UK has recently developed one, DragonFire: https://en.wikipedia.org/wiki/DragonFire_(weapon)It's line of sight and I don’t think there's anything free or eternal about its enery!
There's also research by many others - Directed-energy weapon:https://en.wikipedia.org/wiki/Directed-energy_weaponThe are also plans using mirrors in space to boost solar power production on Earth:https://www.space.com/orbiting-mirror-boost-solar-power-productionI believe the go ahead has been given for a proof of concept of mirrors in space in spite of concerns from the astronomy community that reflecting sunlight into dark areas could blind astronomers. Of course, although there's no charge for sunlight, it's not free because of the cost of building, launching and maintaining the space infrastructure. It's not eternal as presumably, like all infrastructure, it will not last indefinitely, and at some time in the future the sun will run out of hydrogen to fuel its fusion process - although that's probably long after human extinction ...I think we can be fairly sure that the was no directed, free energy used in 9/11 - aside from the lack of advanced technology powerful enough to destroy something as large as the WTC, it would have needed space infrastructure that would have been spotted by thousands of astronomers around the globe beforethe event. So stick with the highjacking of airplanes ... and remember, it wasn't just the WTC, but the Pentagon and, if the plane hadn't crashed because of passenger resistance, probably the White House that were attacked. Many of us watched this in real time with verification from observers from NY confirming it was real ...Looks like just another conspiracy scam to sell books at £28 a pop :-)
