Star Trek’s Montgomery Scott famously said “ye cannot change the laws of physics”, but a real-life space engineer says he might have just done that.

David Burns of NASA’s Marshall Space Flight Center in Alabama has unveiled what he’s calling the ‘helical engine’, which could potentially power flights across space without using any fuel at all.

There’s just one small problem — it breaks the laws of physics as we know them.

New technology plans to tackle the future energy crisis by capturing sunlight and turning it to bioenergy.

TOKYO (Reuters) — Toyota Motor Corp (7203.T) unveiled a completely redesigned hydrogen-powered fuel cell sedan on Friday in its latest attempt to revive demand for the niche technology that it hopes will become mainstream.

Japan’s biggest automaker has been developing fuel-cell vehicles for more than two decades, but the technology has been eclipsed by the rapid rise of rival battery-powered electric vehicles promoted by the likes of Tesla Inc ( TSLA.O ).

Ahead of the Tokyo Motor Show starting on Oct. 24, Toyota unveiled a prototype of the new hydrogen sedan built on the same platform as its luxury Lexus brand’s LS coupe. The new Mirai model boasts longer driving range than its predecessor and completely redesigned fuel cell stack and hydrogen tanks, the company said.

A new treatment plant can make energy, clean water and chemicals.

“It would also need to be big – some 200 metres long and 12 metres in diameter – and powerful, requiring 165 megawatts of power to generate just 1 newton of thrust, which is about the same force you use to type on a keyboard. For that reason, the engine would only be able to reach meaningful speeds in the frictionless environment of space. “The engine itself would be able to get to 99 per cent the speed of light if you had enough time and power,” says Burns.”

A NASA engineer has published plans for an engine that could accelerate a rocket without using propellant. But there are questions over whether it could work.

Since the first aeroplane flight more than 100 years ago, aeroplanes have been propelled using moving surfaces such as propellers and turbines. Most have been powered by fossil-fuel combustion. Electroaerodynamics, in which electrical forces accelerate ions in a fluid^1,2, has been proposed as an alternative method of propelling aeroplanes—without moving parts, nearly silently and without combustion emissions^3,4,5,6. However, no aeroplane with such a solid-state propulsion system has yet flown. Here we demonstrate that a solid-state propulsion system can sustain powered flight, by designing and flying an electroaerodynamically propelled heavier-than-air aeroplane. We flew a fixed-wing aeroplane with a five-metre wingspan ten times and showed that it achieved steady-level flight. All batteries and power systems, including a specifically developed ultralight high-voltage (40-kilovolt) power converter, were carried on-board. We show that conventionally accepted limitations in thrust-to-power ratio and thrust density^4,6,7, which were previously thought to make electroaerodynamics unfeasible as a method of aeroplane propulsion, are surmountable. We provide a proof of concept for electroaerodynamic aeroplane propulsion, opening up possibilities for aircraft and aerodynamic devices that are quieter, mechanically simpler and do not emit combustion emissions.

There is strong evidence from publicly available sources that a Russian company called KB Arsenal is working on a new type of military satellite equipped with a nuclear power source. Called Ekipazh, its mission may well be to perform electronic warfare from space.

KB Arsenal, based in St. Petersburg, is no newcomer to the development of nuclear-powered satellites. In the Soviet days it built satellites known as US-A (standing for “active controllable satellite”), which carried nuclear reactors to power radars used for ocean reconnaissance (in the West they were known as “radar ocean reconnaissance satellites” or RORSAT for short.) The satellites had been conceived in the early 1960s at the OKB-52 design bureau of Vladimir Chelomei before work on them was transferred to KB Arsenal at the end of that decade. The satellites’ three-kilowatt thermoelectric reactors, known as BES-5 or Buk, were built by the Krasnaya Zvezda (“Red Star”) organization. The US-A satellites operated in low Earth orbits at an altitude of roughly 260 kilometers and, after finishing their mission, the reactors were boosted to storage orbits at an altitude of about 900 kilometers.
