You know, the more I think about this, the more I bristle at Dyson claiming this will solve Britain's food security problem.
Firstly, this kind of system seems limited to small cash crops rather than staple foods. (Good luck growing wheat on these.)
More importantly, Dyson has personally done far more to harm British food security than this gadget could offset. He was an ardent Brexiteer, which resulted in substantial barriers to importing food from our closest neighbors. (He also then immediately started relocating his business to Singapore in a stunning show of confidence in post-Brexit Britain)
These people don't want to save the world. They just want to look like heroes
The problem isn't the reward for becoming an MP, it's the cost of campaigning. Candidates are expected to put up £10-30k of their own money to contest a seat. Some spend considerably more.
Personally, I don't think paying MPs more will do much harm, but it won't fix any of the problems with the quality of the politicians we get.
