How efficient is this Army generator? MEP-831A
How much energy can we make per gallon of diesel fuel? I'll be testing an Army generator's fuel economy while re-charging my off grid solar battery bank.
The military generator is model MEP-831A. It's a single cylinder, Yanmar L-70 diesel engine
Electrified cloth extracts uranium from seawater
A team of scientists from China's Northeast Normal University has developed an electrochemical method for extracting uranium from ordinary seawater that has the potential to supply humanity with an effectively unlimited energy source.
Hydrogen Fuel Is Gaining Traction With Truckers
"Outside of Nikola, you're just not seeing large commercial development in North America." Nikola is the front-runner so far in the hydrogen-truck field, but traditional manufacturers including Kenworth, Hyundai Motor and Volvo Trucks are also
Laser Nuclear Fusion
The NT Times had a recent article discussing laser nuclear fusion. Nextbigfuture has spoken with all of the nuclear fusion companies listed in the NY Times article as they all attended the 2023 International Conference on Inertial Fusion Sciences and
Supercritical CO2 pilot aims to make steam turbines obsolete
Steam turbines still produce most of the world's power, but supercritical carbon dioxide promises to be much cheaper, and 10% more efficient as a medium than water, using 10X smaller turbines. A US$155-million pilot plant is now complete in San Anton
3 Ways to Build a Faraday Cage
This video shows three ways that you can build cheap but effective Faraday cages. These could help you protect important electronics from an EMP (electromagnetic pulse).
The SABS BUILDING SYSTEM (Saebi Alternative Building System)
SABS™ is a multi-patented, composite building system that utilizes Expanded Polystyrene Foam (EPS) as the core material for all structural members; walls, roof, and floor. These pieces are assembled with adhesive, without any additional structure s
5 Megawatt solar plant destroyed by hail
Hail destroyed most of the three year old Scottsbluff community solar project in Nebraska this week. Solar energy might be free but collecting it requires vast acreages of fragile and expensive infrastructure.
Hydrogen Will Not Save Us. Here's Why.
Replacing fossil fuel with hydrogen seems like an ideal solution to make transportation environmentally friendly and to provide a backup for intermittent energy sources like solar and wind. But how environmentally friendly is hydrogen really? And how
CATL launches ultra-high density 500-Wh/kg "condensed battery"
In huge news for zero-emissions aviation, Chinese company CATL is set to go to mass production on a "condensed battery" it says can squeeze in more than twice as much energy as a Tesla Model Y battery, by weight – while being safe enough to fly wit
